Determination of blood clotting at home. Traditional methods of healing blood. What is blood clotting and how to determine it

Health 01/11/2018

Dear readers, the ability of blood to clot under certain conditions plays an important role in maintaining the constancy of the internal environment and overall human health. When visiting a doctor, many do not know which specific test is related to determining blood clotting. But if you wish, you can understand this rather complex issue.

What is blood clotting, why is it needed, and how to determine it using diagnostics - a doctor of the highest category, Evgenia Nabrodova, will tell you about this in an accessible language.

Blood clotting ensures the constancy of hemostasis - the system that is responsible for maintaining the liquid state of the blood, stopping bleeding and dissolving waste clots. The basis of this complex process is the formation of a platelet-fibrin clot. During even minor damage to the vessel, an increase in platelet activity occurs. Platelets stick to each other and to damaged tissue, stopping bleeding. This produces enzymes that activate other blood clotting factors.

The test for blood clotting is called a “coagulogram”. This diagnostic method allows you to comprehensively evaluate the hemostatic system, make an accurate diagnosis, decide on further medical tactics and solve many other medical problems.

Even minor bleeding disorders can have dangerous health consequences. Increased blood clotting leads to the risk of blood clots and an increased likelihood of strokes, heart attacks and other complications. Poor blood clotting indicates the likelihood of bleeding. If there is a tendency to hemostasis disorders, it is recommended to periodically carry out a coagulogram and correct the detected disorders.

Indications for testing

A coagulogram allows you to identify blood clotting disorders, establish bleeding time and other important indicators.

The study has the following indications:

preparation for any surgical interventions;
vascular diseases, including varicose veins and thrombophlebitis;
liver pathologies;
autoimmune disorders;
heart disease, high risk of heart attack, coronary artery disease;
use of anticoagulants;
selection of dosage of drugs that thin the blood and prevent blood clots;
use of hormonal contraception;
the use of hirudotherapy, determining the risk of bleeding;
pregnancy, preparation for childbirth.

It is recommended to determine blood clotting not only for direct indications, but also for preventive purposes. With age, the risk of blood clots and the development of cardiovascular diseases increases, many of which are fatal. Today, every person can take a blood clotting test upon the direction of a local physician, cardiologist or other specialized specialist.

This video has a lot of useful information about blood clotting and the importance of this protective mechanism.

The research is carried out using different methods. Main indicators of coagulogram:

blood clotting time;
bleeding time;
prothrombin time;
prothrombin index;
international normalized ratio;
fibrinogen;
activated partial thromboplastin time;
lupus anticoagulant;
antithrombin III;
D-dimer;
APTT coagulogram indicator.

I would like to talk about each indicator separately. The rate of blood clotting in women and men may differ, but experts make the main division into adults and children. The interpretation of the blood test for coagulation and determination of the normal indicators is carried out by a qualified specialist. Results may differ markedly for different conditions.

Clotting time

By determining the blood clotting time, the doctor receives data on how many minutes it takes for a clot to form. This indicator allows you to exclude or confirm hemophilia, disseminated intravascular coagulation syndrome and other disorders. After receiving the results, the doctor will determine the causes of poor blood clotting and select appropriate treatment.

The normal clotting time for adults and children ranges between 5-12 minutes.

Bleeding time

In accordance with international standards, the duration of bleeding (primary hemostasis) should not exceed 8 minutes. The average is 2-3 minutes. It plays an important role in the process of preparing the patient for surgical interventions. Bleeding time increases with hemophilia, thrombocytopenia, alcohol intoxication, overdose of certain medications, hemorrhagic fever and other disorders.

Prothrombin time

Prothrombin time is one of the main indicators of a coagulogram, which reflects the duration of the transition of prothrombin to thrombin, therefore it is used to assess the general condition of the hemostatic system and determine the effectiveness of medications that prevent blood clotting. The normal prothrombin time for women and men is 11-15 seconds, for children - 13-19 seconds.

If the prothrombin time is higher or lower than normal, this may indicate a lack of vitamin K in the body and some blood clotting factors, the development of disseminated intravascular coagulation syndrome, liver failure and other liver diseases. When using anticoagulants, an increase in prothrombin time is also possible.

Prothrombin index (PTI)

The prothrombin index reflects the ratio of the ideal prothrombin time to the existing prothrombin time in a particular patient. The PTI norm for adults is 73-122%. The exception is pregnant women, in whom blood clotting is usually increased.

International normalized ratio (INR)

The international normalized ratio is the ratio of the prothrombin time obtained as a result of the analysis to its average value or to the norm. A decrease in this indicator indicates a high probability of thrombosis, an increase indicates a risk of bleeding. The general INR norm is 0.82-1.18. Today, experts pay less attention to the result of determining PTI, which is considered less informative than INR data.

Fibrinogen

Fibrinogen is a precursor to fibrin, which is the basis of a blood clot. Its norm in adults is 2.7-4.013 g/l, in a child in the first days of life - 1.25-3 g/l. The amount of fibrinogen increases during necrotic processes, inflammation, and an increased risk of developing cardiovascular diseases due to thrombosis. A decrease in this indicator may indicate the progression of DIC syndrome, liver pathologies, and congenital hemorrhages.

Activated partial thromboplastin time (aPTT)

Determination of APTT is considered a screening method for assessing blood coagulation. It is especially important for people who receive heparin or suffer from disseminated intravascular coagulation syndrome and other bleeding disorders. Using this coagulogram indicator, specialists determine the rate of formation of a blood clot when using certain reagents. A decrease in APTT indicates a risk of thrombosis, while a prolonged APTT indicates a decrease in blood clotting and the likelihood of bleeding.

Lupus anticoagulant

Normally, lupus anticoagulant is not detected. If it is detected, specialists may suspect the development of autoimmune disorders and gestosis of pregnancy. If the results of a coagulogram reveal specific antibodies, this indicates the development of thrombosis. For pregnant women, determination of the lupus coagulant can result in spontaneous abortion, loss of pregnancy and placental infarction.

Antithrombin III

Determination of antithrombin III is carried out to assess the functioning of the anticoagulant system and identify the likelihood of thrombosis. The indicator is also determined as part of the monitoring of heparin treatment. Antithrombin III increases with the development of obstructive jaundice, acute hepatitis, and inflammatory processes. In women, antithrombin III may increase during menstruation. A decrease in the indicator allows one to suspect abnormalities in the liver and the progression of DIC syndrome. The norm of antithrombin III is 75.8-125.6%

D-dimer

D-dimer is a fibrin filament that is cleaved. For specialists, only an increase in this component is important, which indicates a high likelihood of developing liver diseases, thrombosis, arthritis, cardiovascular diseases and disseminated intravascular coagulation syndrome.

Constancy of hemostasis is especially important for pregnant women. Blood clotting disorders often lead to hypoxia, gestosis, placental abruption, and infectious complications. Blood clotting during pregnancy is usually slightly increased. Experts know about this feature. But in any case, diagnostics are carried out in each trimester and always before childbirth.

The rate of blood clotting in pregnant women may differ from the coagulogram data of non-pregnant women. For example, the prothrombin index in the first trimester ranges from 85-90%, in the second trimester - 91-100%, in the third -105-110%. Fibrinogen at the beginning of pregnancy is lower than in the last trimester. In the first months it is 2.91-3.46 g/l, and before childbirth - 4.42-5.10 g/l. Platelets, on the contrary, are elevated in the first trimester (310-317) and decrease towards the end of pregnancy (240-260).

During pregnancy, both increased and decreased blood clotting is dangerous. If a specialist detects any abnormalities based on the results of a coagulogram, an expanded comprehensive diagnosis is prescribed and appropriate treatment is selected. Poor blood clotting during pregnancy can result in massive bleeding and complications during childbirth. The state of hemostasis directly affects the safety of the fetus.

Increased blood clotting during pregnancy is considered normal. But when the level of fibrinogen rises sharply, the blood thickens, which leads not only to the risk of blood clots, but also to the development of preeclampsia. The child begins to suffer from lack of oxygen and nutritional deficiencies. Specialists should be attentive to coagulogram parameters and especially to the amount of fibrinogen.

When is it necessary to check blood clotting?

Blood clotting must be checked before surgical interventions, during childbirth and before a planned caesarean section. Also, any person has the right to take the test at his own request or as prescribed by a doctor. To do this, you need to make an appointment with your local therapist or specialized specialist who is treating you and simply ask for a referral. Do not hesitate to do this: a doctor is obliged to deal not only with the treatment of diseases, but also with high-quality prevention.

A blood clotting test is a test that is recommended for all people to check for the risk of blood clots or bleeding. The likelihood of developing blood clots increases with age. Ideally, blood is donated for coagulation 1-2 times a year, even in the absence of complaints (after reaching 35-40 years old - the age of risk).

Increased blood clotting

The increase in blood clotting practically does not manifest itself in any way. A tendency to form blood clots can be noticed by health workers who give intravenous injections or conduct laboratory diagnostics: with age-related or normal increases in clotting, the blood becomes like porridge and literally coagulates on a needle.

Other symptoms may also occur (combined with age-related hypertension and atherosclerosis):

blood pressure surges;
headache;
noise in the head;
increased fatigue;
coordination problems.

Reduced blood clotting

With a decrease in blood clotting, the risk of bleeding increases: uterine, nasal, intraorgan. Internal blood loss is especially dangerous, which can result in the death of the patient. Such conditions are classified as acute. They are difficult to miss for both patients and doctors.

A decrease in blood clotting (in case of violation of various hemostasis factors) is accompanied by the formation of hemorrhages, hematomas and bruises. If a bruise appears after a small pinch on the skin, it is necessary to check the blood for clotting.

With frequent bleeding from the nose, gums, genitals, due to mild trauma to the skin, signs of anemia appear:

pallor of the skin and mucous membranes;
weakness;
drowsiness;
deterioration in performance;
decrease in blood pressure;
headache;
shortness of breath with slight exertion.

If you are prone to bleeding, you must immediately take a blood clotting test.

Before the blood clotting test, it is recommended to fast for 8-10 hours. The subject of the study is peripheral venous blood. Before the procedure, you are allowed to drink purified water, but you should not drink coffee or fruit juices. If the patient is using drugs that increase blood clotting, the doctor must be informed about this in advance. This information must be reflected in the referral for laboratory testing.

A blood clotting test is taken in the morning on an empty stomach. The results are interpreted by the attending physician.

Even if patients receive a test with coagulogram data, they must go to a specialist with it. When trying to independently interpret the results of a study, there is a high risk of errors and inaccuracies.

Treatment

Depending on the results of the blood clotting test, specialists prescribe appropriate treatment. Data from other diagnostic methods are also taken into account. Depending on the severity of the patient’s condition, medications may be prescribed to increase or decrease blood clotting and hemostatic replacement therapy with blood clotting factors.

Some hemostasis disorders require urgent hospitalization and anti-shock therapy. Such an emergency condition is DIC syndrome. Patients are injected with fresh frozen plasma, red blood cells, and saline. For bleeding, antifibrinolytic drugs are prescribed.

Today we will listen for the soul Irina Bogushevskaya. The keys are in your hands . The video uses footage from the movie “Fan-Fan Scent of Love.” Irina’s songs are always so amazing.

Blood clotting is a very important protective reaction of the human body. It prevents blood loss, while maintaining a constant volume of blood in the body.

The coagulation mechanism is triggered by a change in the physicochemical state of the blood, which is based on the fibrinogen protein dissolved in its plasma.

Fibrinogen is able to turn into insoluble fibrin, which falls out in the form of thin threads. These same threads can form a dense network with small cells, which traps the formed elements.

This is how a blood clot happens. Over time, the blood clot gradually thickens, tightens the edges of the wound and thereby promotes its speedy healing.

When compacted, the clot releases a yellowish clear liquid called serum.

Platelets also participate in blood clotting, which thicken the clot. This process is similar to making curd from milk, when casein (protein) is curdled and whey is also formed.

During the healing process, the wound promotes gradual resorption and dissolution of the fibrin clot.

Coagulation is a rather complex biological process. During this action, fibrin is formed - a special protein necessary for the formation of clots.

It is because of them that the blood becomes less liquid, its consistency begins to resemble cottage cheese. The blood clotting rate largely depends on this protein.

The regulation of coagulation depends on two body systems: nervous and endocrine. Due to fluidity, blood cells do not stick together and can easily move through the vessels. Several functions depend on the state of the liquid:

trophic;
transport;
thermoregulatory;
protective.

When the integrity of the vascular walls is violated, there is an urgent need for the clotting process: without the formation of a clot in the problem area, a person can be seriously injured.

Blood retains its liquid form due to a special anticoagulant system, and hemostasis is responsible for the formation of clots.

Types of blood clots

There are 3 types of blood clots or thrombi:

A white thrombus is formed from fibrin and platelets; it contains a relatively small amount of red blood cells. Usually appears in those places of vessel damage where the blood flow is high (in the arteries).
Disseminated deposits of fibrin form in capillaries (very small vessels). This is the second type of blood clots.
And the last ones are red blood clots. They appear in places of slow blood flow and with the obligatory absence of changes in the vessel wall.

Deviations from the norm and their causes

If blood clotting occurs either too slowly or too quickly, then the indicators are not within normal limits.

All these reasons can cause accelerated clot formation with lesions of the skin and blood vessels. However, often increased blood clotting becomes a consequence of some disease, which can only be determined by a doctor by examining the symptoms and conducting laboratory tests.

Pathological deviations are often caused by diseases of various types.

The main causes of increased blood clotting:

viral infections;
hormonal disorder;
liver disease, spleen;
bearing a child;
disruption of the blood system due to a sedentary lifestyle;
heredity;
dehydration;
exposure to radiation therapy;
changes in metabolic processes;
autoimmune disorders.

Increased blood clotting causes changes in the composition and density of blood plasma. This changes the content of red blood cells and platelets, which promotes thrombus formation in the blood vessels and heart.

Therefore, high blood density requires timely treatment.

Diagnostics: preparation and procedure

Like any other, a blood clotting test requires some preparation. Regardless of the purpose of the procedure, it is important to adhere to the following rules:

Do not eat for at least 8 hours before the test.
Do not drink alcoholic beverages – 24 hours.
No smoking – 3 hours.
For a couple of hours before the test, avoid any physical activity and remain completely at rest until blood is drawn.
It is necessary to undergo the procedure only in the morning.

The process of taking blood, that is, conducting an analysis, depends on its purpose. Basically the procedure is carried out as follows:

The patient's skin is pierced on the “pad” of one of the fingers with a special sharp instrument (needle, scarifier). If venous blood is needed, it is collected from a peripheral vein with a syringe.
Then blood is drawn, at least 20 ml.

After the above operations, within 2 hours, the analysis material is delivered to the laboratory, where blood clotting indicators are checked.

Norms of analysis indicators and reasons for their deviation

The analysis process involves identifying several factors at once. Depending on age, pregnancy or other phenomena inherent in the human body, blood clotting rates may differ.

In such situations, it is necessary to take into account the characteristics of each individual patient. Fortunately, there are averages for everyone, which are presented below:

Bleeding. No less important than laboratory indicators is the empirically determined bleeding time from the moment the epithelium on the finger is punctured. The norm is that the bleeding stops after 2-3 minutes. If the period is extended, then problems such as vitamin C deficiency, thrombocytopenia (reduced number of platelets), negative effects of medications taken by the patient are quite possible.
Aggregation. This phenomenon characterizes the connectivity of platelets in human blood. The aggregation norm is considered to be 0-20%. A decrease in this indicator to 0-5% is not a good sign and occurs due to some rare diseases. An increase in the level of aggregation is not a rare phenomenon, and indicates the appearance of such ailments as: myocardial infarction, thrombosis, diabetes mellitus and atherosclerosis.
Adhesion. Adhesiveness is an indicator that determines the level of platelet adhesion to defective (damaged) vessel walls. The norm for this indicator is in the range of 20-50%. An increased level of adhesion is a very rare phenomenon and does not entail anything super-serious. But a decrease indicates the progression of acute leukemia or renal failure.
Blood clotting outside the body. It is determined by the period of time from the beginning of taking blood from a vein or finger until the first manifestations of coagulation, but already on a glass slide or in a flask. For capillary blood, the norm is 3-5 minutes, for venous blood - 5-10 minutes. A decrease in clotting time can be affected by taking certain medications, while an increase can be caused by hemophilia, liver problems, or taking an anticoagulant.
PTI (prothrombin index). This point is determined by calculating the ratio between the clotting time blood plasma in a patient and a similar indicator in a completely healthy person. The norm for the PTI indicator is 90-107%. The prothrombin index primarily determines the condition of the human liver, since the determined particles are synthesized in this organ. An increase in PTI indicates the development of thrombosis, and also occurs with long-term use of oral contraceptives and in the period 2-4 months before childbirth. A decrease in the index is characterized by a decrease in vitamins of group K in the blood, which is inherent in diseases such as dysbacteriosis and enterocolitis.
The amount of fibrinogen in the blood. Fibrinogen is a protein that is produced in the liver and, under the influence of certain factors, turns into fibrin, which is responsible for blood clotting. The normal indicator is 2-4 g/l. Its determination is especially important during pre- and postoperative periods, pregnancy and inflammatory processes in the human body. A decrease indicates the possible presence of liver disease ( cirrhosis ), hepatitis and low levels of vitamin B12, less often C. Fibrinogen in the blood increases during inflammation of various types, myocardial infarction, pneumonia, and also in the postpartum period.
Thrombin time. A complex indicator that determines the time during which fibrinogen is converted into fibrin. The normal thrombin time is 14-18 seconds. An increase indicates kidney problems or some defects of the immune system, a decrease indicates an excess of fibrinogen in the blood.
Activated partial thromboplastin time (aPTT). APTT is a complex chemical process that directly affects the rate of blood clotting. The norm for this indicator can be considered 30-40 seconds. Its decrease indicates the development of hemophilia, its increase indicates a lack of vitamins K and liver problems.

Important! All indicators are required to be considered, since none of them can be considered separately, because only together they ensure normal blood clotting.

Treatment methods

Having taken a blood clotting test and discovered that you have deviations from the norm, you must act strictly depending on the situation.

It is worth understanding that, for example, in women some indicators may deviate from the norm during periods of menstruation, taking hormonal drugs, pregnancy, lactation, or in men and children during periods of taking fish oil.

The results of the analysis are also significantly affected by excessive dehydration of the body or inflammatory and infectious processes occurring in the human body.

Therefore, only by taking into account such factors and carefully listening to the doctor’s advice can you understand. whether treatment measures need to be taken or not.

Treatment is prescribed by the doctor depending on the test results.

There are a huge number of ways to normalize blood clotting indicators, but the main ones are the following:

treatment of diseases kidney or liver
systematic intake of deficient vitamins
taking special medications
lifestyle change

Important! Normalization of blood clotting indicators is a strictly individual process, therefore, in this case, neglecting the help of a doctor is strictly prohibited.

You can learn more about the blood coagulation system from the video:

In conclusion, it is worth noting that blood clotting standards are a rather vague indicator and in most cases are determined individually for each patient.

In any case, having some idea of their average values, you can significantly clarify your understanding of a certain situation.

How is treatment carried out if blood clotting is increased?

You should regularly undergo tests that allow you to timely detect the presence of thrombophilia. When a diagnosis is made, medications are prescribed and fibrinolytic therapy is carried out.

A blood test allows you to identify the cause of the disease and choose the right treatment. It is necessary to donate blood for D-dimer, which allows you to detect kidney disorders and the amount of vitamin K.

These tests are especially important for pregnant women. In addition, this allows you to determine the condition of the heart and blood vessels.

In some cases, such information allows you to take timely measures and avoid death.

There are several methods for treating increased blood clotting:

In classical medicine, antithrombotic therapy is carried out.
The patient is prescribed drugs from the group of anticoagulants. These medications prevent platelet formation a lot.
Rapid relief of the condition is achieved by taking heparin and aspirin in small dosages.

If there is a diagnosis of atherosclerosis, then in order for the blood to clot more slowly, aspirin is prescribed in small dosages.

In addition, today there are cardio aspirins that contain magnesium. It is very useful for people over 40 to take them regularly.

It is especially important to monitor your condition for people who have vascular diseases.

Hereditary thrombophlebitis, including in childhood, is also treated with small doses of aspirin. In a critical situation, the administration of anticoagulants C and S, antithrombin III, and drugs that are analogues of hirudin is used.

If drug treatment does not bring results, then surgery is performed.

It should be recalled that you should not take blood thinning medications on your own, as this can lead to serious and even dangerous consequences.

Therapy technique for normalization

blood clotting

Treatment depends on the nature of the disease; antispasmodics and anti-inflammatory drugs are prescribed individually. In severe cases, transfusion therapy or surgery is performed to remove blood clots.

All treatment is carried out under the supervision of the attending physician with regular blood tests. Thinning medications can cause internal bleeding. Therefore, it is forbidden to self-medicate at home.

In addition to drug therapy, it is necessary to follow a special diet. The diet should be balanced, give preference to fresh vegetables, fruits, eat fish, seaweed.

It is important to drink at least two liters of water per day and give up coffee, carbonated and alcoholic drinks.

For hereditary pathologies, doctors prescribe aspirin in small dosages over a long period. While pregnant, aspirin is contraindicated. All medications are prescribed by the gynecologist-obstetrician on an individual basis.

Drug effects

If the right foods and drinking regimen do not produce visible results, the doctor may prescribe special medications. Anticoagulants, or drugs that increase the ability of blood to thin, are taken in a course, the duration of which is determined by a specialist based on the collected medical history and laboratory tests.

You can reduce blood density with the help of plants and decoctions for a short period of time, but to normalize all its functions you will need long-term use of medications.

Reducing clotting if it deviates from the norm means solving a number of problems and getting rid of the risk of intoxication and blood clots.

Treatment in this case is vital. The longer the blood remains inadequately thick, the higher the risk of pathologies and even death.

It is important to remember that you cannot get by with folk remedies alone: any health problem must be addressed by a qualified specialist.

Treatment of increased blood clotting requires constant monitoring of results through tests. An ordinary person cannot carry out such control on their own, so you should trust the professionals.

How to treat high blood clotting with folk remedies

If blood clotting is increased, then traditional medicine can also be used. It must be remembered that they must be taken in strict dosage and under the supervision of a doctor.

First of all, you should review your diet. It is necessary to maintain a sufficient amount of fluid in the body.

Cucumbers and red grapes contain a lot of liquid, so they should be present in the diet constantly. You need to drink 0.5 cups of red grape juice a day and brew cranberry tea.

You need to introduce foods containing iodine into your diet. Especially useful are seaweed, sea fish, seafood, walnuts, and almonds.

Garlic is very useful in this regard. Eat melons, grapefruits, red bell peppers and tomatoes every day.

Sepsis or blood poisoning - causes and symptoms

The ability of blood to clot is protective. Without this ability, human life would be under constant threat. But there are often cases when various malfunctions occur in the body that negatively affect this feature. And then, you need blood clotting and other laboratory tests to help identify the cause of what happened.

How to determine the normal level of blood clotting.

First, you should familiarize yourself with how blood turns into a dense clot. Any damage to the walls of blood vessels releases certain proteins called fibrins, which are responsible for the protective function. The platelets that are closest to the site of injury begin to change their shape. They become like balls with special processes that allow the cells to stick together. Thus, the tissue rupture site is blocked, which prevents blood from leaving the vessels. The blood itself acquires a cheesy consistency and ceases to be viscous. This mechanism also prevents harmful substances from entering the wound. We can conclude that the task of blood clotting is to prevent the loss of the main fluid in the body. In medicine, this process is usually called hemostasis. But poor blood clotting does not provide maximum protection to the body, which is very dangerous. Increased blood clotting also poses a risk to human health, since...

In what cases is analysis necessary?

It is advisable to check for a malfunction of the hemostasis mechanism if:

Disturbances in the functioning of the hematopoietic organs (bone marrow pathology, liver problems);
Varicose veins, tendency to thrombosis;
Diseases of the cardiovascular system;
Vitamin deficiency;
Failure in the immune system.

It is also recommended to carry out tests during therapy with certain medications (antibiotics, aspirin, cytostatics), as well as when planning pregnancy, before various operations. Some people are interested in what the inability of blood to clot is called when it is inherited. We are talking about hemophilia. This genetic disease is transmitted only to the male sex, and women can only act as carriers of this gene. If a clotting problem is identified in a timely manner, you can protect yourself from irreparable consequences, so it is very important to carry out special laboratory tests in a timely manner.

Normal indicators

To figure out whether there are problems, you need to know what the normal blood clotting level is:

Bleeding time is studied from the moment the finger is punctured. It is considered that the blood clotting time is normal if the bleeding stops after 2-3 minutes from the start of the procedure;
Aggregation - the connectivity of platelets is examined, an indicator of 0-20% is considered normal;
Adhesion - this indicator is responsible for the adhesion of platelets to the walls of blood vessels that have been damaged. Its natural level is 20-50%;
Coagulation outside the body - the countdown of time begins from taking blood and ends after it hardens in a medical container or glass. For capillary and venous blood, 3-5 and 5-10 minutes are sufficient, respectively;
Prothrombin index is determined between the clotting time of a patient and a healthy person. The norm is 90-107%. In women at the end of pregnancy, the PTI rate may be slightly increased;
Fibrinogen – in men and women, if they are healthy, the level is 2-4 g/l;
Thrombin time - fibrinogen should turn into fibrin in 14-18 seconds;
APTT, which stands for activated partial thromboplastin time, is normal at 30-40 seconds.

Blood clotting can only be determined in laboratory conditions. Such studies are carried out by qualified medical professionals. There are many types of such analyses, among the common ones it is necessary to highlight:

According to Sukharev's method. Capillary plasma is used, it is taken from a finger in a volume of 30 mm. Afterwards, the specialist shakes the container and records the time when the sample begins to thicken;
According to Morawitz. Capillary blood is used, it is placed on a special glass, and a stopwatch is turned on to determine clotting. Every half minute, the sample is checked using a glass tube, and the time of appearance of the fibrin thread will be the result of the analysis;
According to the Duque method. The patient's skin is pierced on the earlobe. This is done with a special needle (Frank). The puncture site is soaked with special paper, which is done every 15 seconds. The result of the study will be the time when blood stains will no longer remain on the paper.

It is necessary to carefully prepare for the diagnosis. To do this, it is enough to adhere to the following established rules:

Do not eat food 8 hours before the test;
Day ;
Do not smoke 3 hours before the test;
A couple of hours before blood sampling, do not overload the body with physical activity;

Capillary blood analysis

When examining capillary blood, you can refer to the following tests:

Platelet level analysis;
Prothrombin index (PTI);
Clotting time according to Duka, Sukharev.

When donating venous blood, the patient can count on the following studies:

Lee-White clotting time;
Thrombin time;
Prothrombin index;
Fibrinogen.

Decoding the results

Decoding the test results is very important for taking further actions. You should consider the normal platelet level by age:

Two-week age - women 144-449 thousand/µl, men 218-419 thousand/µl;
Up to 4.3 weeks - 279-571 and 248-586 thousand/µl in women and men, respectively;
Up to 8.6 weeks – in women at the level of 331-597 thousand/µl, and in men 229-562 thousand/µl;
Up to 6 months - in women and men the indicator is normal at 247-580 and 244-529 thousand / μl, respectively;
Up to two years of age – in women 214-459 thousand/µl, in men 206-445 thousand/µl;
Up to 6 years – 189-394 and 202-403 thousand/µl in women and men, respectively;
For more than 6 years, a score of 150-400 has been considered the norm, regardless of gender.

Deviation of values in the analysis

If studies have shown that a patient has poor blood clotting, he should look into this issue in more detail. Namely, what could influence the deviations:

Prolonged bleeding after pricking a finger indicates vitamin C deficiency, the negative effects of various medications and thrombocytopenia;
If the aggregation rate is more than 0-20%, this indicates the presence of diabetes mellitus, thrombosis, myocardial infarction, atherosclerosis;
A reduced level of adhesiveness indicates the occurrence of such serious diseases in the body as renal failure;
If there is an increased rate of coagulation outside the body, liver disease is suspected, or the patient is using an anticoagulant;
A decrease in PTI is characterized by a lack of vitamins belonging to group K. This may also indicate dysbacteriosis, enterocolitis;
The protein fibrinogen also indicates health problems. So, if it is low, the patient may have cirrhosis, hepatitis, low levels of vitamin B12, and if it is high, various inflammations, pneumonia,;
An increase in thrombin time is a sign of kidney disease and immune failure;
A decrease in aPTT means hemophilia develops, and an increase means there is not enough vitamin K in the body, and there are kidney diseases.

Causes of poor blood clotting

The previously mentioned reasons for deviations in this protective function of the body must also include the last stage of DIC syndrome, which appears as a side effect of sepsis and soft tissue abscess. If you experience poor blood clotting during pregnancy, you can reduce the risks to the health of the baby and mother by taking special “gentle” medications.

Symptoms of poor clotting

Among the main symptoms indicating a failure of the defense mechanism are:

Frequent cases of hematomas under the skin, despite the fact that this occurs after minor physical impact;
Nosebleeds, red blood cells may be excreted in the urine;
Blood on the toothbrush;
Unreasonable appearance of microscopic cracks and wounds on the skin;
Anemia, manifested by weakness, hair loss, brittle nails, dizziness, constipation, diarrhea.

Having received the results of the study, you can begin to find a solution to increase blood clotting. Such recommendations are given only by the attending physician, and not by a neighbor or the first Internet user you meet. Only a medical professional can accurately confirm deviations from the norm. The fact is that there are some nuances. For example, during pregnancy, menstruation, taking hormonal medications, and lactation, some indicators may change and not be normal. The same is observed when consuming fish oil in children and men.

Dehydration, infection and inflammation also have a significant impact on test results. Therefore, only a doctor, referring to these points, will indicate whether treatment is necessary or not. Treatment of the disorder can be specific or non-specific. The latter includes the exclusion of causes that provoke poor clotting. Doctors tirelessly repeat the need for timely treatment of diseases and normalization of diet. For therapy, doctors prescribe special medications, which must be taken strictly under the supervision of a specialist. These medications include:

To increase fibrinogen protein, Contrical, aminocaproic and tranexamic acid are administered intravenously;
Vikasol, as well as other coagulants characterized by an indirect mechanism of action;
Fibrins, which patients receive through donor blood;
If poor clotting is observed after using Heparin or antiplatelet agents, Protamine sulfate is prescribed;
Vitamin K;
For Willenbrand disease and hemophilia, Cryoprecipitate, antihemophilic plasma is injected into a vein;
Problems with platelets are solved with the help of the drug Oprelvekin, as well as Hydroxyurea.

Treatment must be supplemented with a special diet that will help you achieve the desired result faster. So, the patient should add to his menu foods that contain large amounts of calcium, folic acid, amino acids and vikasol. It can be cottage cheese, cheese, kefir. An important role in the recovery stage is played by the consumption of meat, fish, broccoli, spinach, green onions, carrots, white cabbage, legumes and grains. It’s a good idea to add orange, rose hips, quince, barberry, watermelon, blackberries, currants, apples, strawberries, viburnum, cherries, etc. to your diet.

In folk medicine, to combat this problem, decoctions and infusions are prepared from the following plants and herbs:

Chokeberry, which in addition to increasing coagulability, strengthens blood vessels. In the presence of hypotension, it should be used with caution, as it affects the decrease in blood pressure;
Stinging nettle and knotweed, they affect sugar, reducing it, and also increase hemoglobin;
Millennial, which has a dilating effect on blood vessels, stopping bleeding and reducing inflammation.

Knowing how to increase or decrease blood clotting, you can avoid negative health consequences. It is important to do everything in a timely manner!

Blood clotting concept

Coagulation is the process of turning blood into an elastic clot when it flows from a damaged vessel. This occurs as a result of the fact that any injury to the bloodstream provokes the transition of fibrinogen (a protein found in the blood plasma) into the insoluble protein fibrin, which, forming a clot, clogs the vessel at the site of its damage.

Blood clotting is a protective reaction that protects the body from large blood loss when the integrity of blood vessels is violated. Clotting time is determined by how quickly a blood clot forms. Blood clotting studies are carried out using specially developed methods.

Indications for the purpose of analysis

Doctors of different specialties can prescribe a test to determine blood clotting time. It is extremely necessary to undergo an examination in the following cases: pregnancy, various liver diseases, varicose veins and other pathologies of the vascular system, increased risk of thrombosis, autoimmune diseases. Determination of blood clotting time is also prescribed before planning various surgical interventions and during the recovery period after them.

How to properly prepare for research?

The material for the study is blood taken from a vein or finger. You must donate blood in the morning on an empty stomach. If there is a need to carry out the analysis at another time of the day, then at least three hours before the test you should not eat. You can't drink tea or coffee either. You can only drink plain water.

The time it takes for blood to clot is calculated from the moment it is taken for analysis until the start of clotting. Today, two main methods of performing this analysis are used - determining the blood clotting time according to Sukharev and according to Lee-White. It should be remembered that none of them determines the reason for the slowdown or acceleration of coagulation. This requires more in-depth studies of the patient’s hemostasis system.

Blood clotting according to Sukharev

To carry out this test, blood is taken from a finger, filling it with a special container-tube - the Panchenkov capillary. When collecting material, the first drop is removed with a swab, after which the capillary is filled with blood so that the height of the blood column is 25–30 mm. Next, the laboratory assistant turns on the stopwatch and tilts the horizontally located capillary in one direction and the other every 30 seconds. At the very beginning, blood moves freely inside the “tube,” but when the coagulation process begins, its movement slows down. When clotting is complete, the blood stops moving completely. The norm in this case will be the following time indicators: the beginning of the process - from 30 to 120 seconds, complete completion - from 3 to 5 minutes.

Lee-White method

During this examination, blood is taken from a vein. The technique for carrying it out is much more complex than that described above and consists in the fact that the blood clotting time is determined under strict temperature conditions (37 ° C) in two test tubes (regular and treated with silicone). In the first test tube, if all conditions are met, the blood normally clots in 5-7 minutes, in the second - in 15-25 minutes. The ratio of the second time to the first is called the contact index, the normal values of which should be in the range from 1.7 to 3.0 conventional units.

Decoding the results

If, as a result of the analysis, the blood clotting time turned out to be longer than normal (reduced clotting), this may indicate pregnancy, anemia due to acute blood loss, aplastic or hypoplastic anemia, liver pathology, impaired platelet function or a decrease in their number, poisoning with mustard gas or phosgene, leukemia, hemophilia , overdose of drugs containing acetylsalicylic acid (aspirin).

If the blood clotting time is much less than normal (thick blood), the reasons for this may be infectious diseases, hormonal imbalance, atherosclerosis, dehydration, metabolic disorders, slow blood flow due to lack of physical activity, radiation, autoimmune diseases.

Blood clotting- this is the body’s most important ability to stop bleeding when the walls of blood vessels are damaged, and to resolve blood clots when they are no longer needed. The concept of blood clotting is inextricably linked with the homeostasis system, the function of which is to preserve blood. Homeostasis has two mechanisms:

Primary – vascular-platelet. In this case, platelets stick together and form a so-called “white thrombus”, in which platelets predominate.
Secondary – coagulation (aka blood clotting). It creates a dense blockage of the damaged area with a fibrin clot, which is also called a “red thrombus.” It received this name due to the fact that the fibrin mesh mainly consists of erythrocytes.

Thus, the process of blood clotting is quite complex and its role in the body is very significant. Any pathologies associated with blood clotting can indicate diseases and lead to them. It should also be clarified that the final stage of homeostasis is fibrinolysis, in which the blood clot is destroyed when the vessel has been restored and the need for a fibrin clot has disappeared.

Indicators for performing a blood clotting test

The blood clotting test is also called coaguloramma. To take a blood test for clotting, you need to decide on the indication. In a number of diseases, blood clotting may be impaired, and their presence is the basis for testing clotting ability:

autoimmune diseases;
liver dysfunction;
cardiovascular pathologies;
phlebeurysm;

Also, a clotting test is necessary for certain conditions:

pregnancy;
postoperative or preoperative period;
control during treatment with anticoagulants;
If a prolonged blood stop is suspected, a clotting test is necessary.

Interpretation of a blood test for coagulation

Before talking about the norm of the blood clotting test, it should be clarified that in each laboratory these indicators may differ slightly, and therefore the final word belongs to the attending physician. You also need to understand that coagulogram norms differ during pregnancy depending on the trimester.

So, a general blood test for coagulation contains 8 standards by which blood clotting is assessed:

How is a blood clotting test performed?

Blood clotting testing is often carried out in vitro, but, for example, when assessing the coagulability of whole blood - thromboelastography, measurements close to in vivo conditions are possible.

To do a general blood test for coagulation, you should not eat food 8 hours before the test. Blood for analysis is taken from a vein to evaluate venous blood. To assess the clotting ability of capillary blood and platelets, it is enough to analyze blood from a finger.
