Coagulogram norm in the table
Normal coagulogram indicators in the table include optimal indicators. Thus, when conducting the analysis, a person receives several numbers as a result. These include APTT, Fibrinogen, Lupus coagulant, Platelets, Prothrombin, TV, D-Dimer and Antithrombin III.
If we are talking about an extended analysis, then the following indicators are added to these indicators: Prothrombin time, Protein S, Protein C and Von Willebrand Factor.
All these "elements" should have certain numbers. They indicate that everything is normal, or has a slight deviation. In normal form, the indicators should be as follows:
| Coagulogram indicator | Norm |
| APTT | 17-20 sec |
| Fibrinogen | up to 6.5 g/l |
| Lupus anticoagulant | should be absent |
| Platelets | 131-402 thousand/mkl |
| Prothrombin | 78-142% |
| Thrombin time | 18-25 sec |
| D-dimer | 33-726 ng/ml |
| Antithrombin III | 70-115% |
In case of any deviations, the coagulogram norm does not match the given data. Such a phenomenon requires finding out the cause and eliminating the problem itself.
The coagulogram indicators are normal if there are no negative processes in the human body. Moreover, if the patient does not take indirect coagulants, then changing the main "elements" is simply impossible.
If there are still deviations, it is imperative to find out the reason. The fact is that a decrease in some indicators can lead to thrombus formation, which is especially dangerous for a person. If we are talking about a pregnant girl, then any deviations can provoke not only the formation of blood clots, but also premature detachment of the placenta. Therefore, the coagulogram norm should always be monitored, this will help to avoid serious complications.
Coagulogram norm INR
The coagulogram norm depends on many indicators. Thus, this "element" is the calculated data, thanks to which it is possible to find out the ratio of the patient's prothrombin time to the average prothrombin time. This indicator is necessary for therapy with indirect coagulants.
The fact is that these medications can worsen blood clotting and lead to serious problems. Patients who are on such therapy should monitor the INR indicator.
Normally, this "element" is less than 1.25. If the figure is too low or too high, it is necessary to look for the cause of this phenomenon. Basically, a sharp decrease in INR indicates an insufficient effect of anticoagulants, which requires certain intervention. This process can lead to a significant risk of thrombosis. The norm of the coagulogram of the INR indicator should not fluctuate, because otherwise it is harmful to the body and most likely the negative process has already begun.
Fibrinogen norm
The norm of the coagulogram fibrinogen, if violated, can lead to increased bleeding. This indicator hides a specific protein. It refers to the main component of the thrombus, which can form during blood clotting. Fibrinogen, due to its qualities, is responsible for many functions regarding the clotting process.
This indicator fluctuates most strongly during pregnancy, and there is nothing to worry about. But still, a woman should be under the supervision of a doctor. After all, in some cases, this may indicate the presence of an inflammatory process or the risk of developing cardiovascular complications. All this can occur against the background of increased blood clotting, which is not normal. In general, this indicator should not exceed 6.5 g / l.
If it decreases significantly, severe bleeding may develop, which may be congenital. It is worth monitoring the "element" during pregnancy, and paying special attention to this moment. After all, the coagulogram norm of this indicator must be observed.
PTI coagulogram norm
The norm of the bird's coagulogram is the ratio of the coagulation time of normal plasma to the coagulation time of the patient's plasma. This number should be expressed as a percentage and not exceed 78-142%.
This indicator can increase, but only if there is a risk of developing blood clots. The given number decreases if there is a tendency to bleeding. That is why it is necessary to pay special attention to it.
It is necessary to note the fact that in pregnant women this indicator can vary slightly and this is the norm. However, this may be due to premature detachment of the placenta.
An increase in the index indicates increased blood clotting. This is not entirely good, because it can lead to the development of cardiovascular diseases. In some cases, the indicator varies due to long-term use of oral contraceptives. In any case, the true cause of this phenomenon must be determined. The norm of the coagulogram of the prothrombin index must be observed.
Normal coagulogram RFMK
The norm of the coagulogram rfmk depends on many things. Basically, this indicator is necessary to determine the amount of soluble complexes in the blood.
These "elements" are markers of thrombinemia during intravascular blood coagulation. This indicator can only be determined manually. Naturally, the procedure is not complicated and is carried out quite quickly. Ideally, there should be no complexes in a person's blood at all.
RFMC is not at all mandatory. Rather, it is done before serious surgical intervention. This indicator is taken from the blood that was submitted for analysis. The higher the concentration of complexes in it, the higher the risk of intravascular thrombosis. Therefore, RFMC plays a significant role.
Its decrease indicates treatment with heparin. This is quite effective when it is necessary to prescribe heparin prophylaxis or heparin therapy. RFMC coagulogram norm should not go beyond 0-0.4.
Coagulogram norm D-dimer
The norm of the coagulogram D-dimer plays a significant role. Thus, this indicator is a product of fibrin breakdown. It shows violations of the blood coagulation process. This element is especially important in the diagnosis of thrombosis, pregnancy and oncological diseases.
Dimer has always been considered a specific degradation product that is part of the thrombus. Based on these data, it is possible to monitor the intensity of the processes of formation and destruction of fibrin clots.
This indicator can be affected by many factors. Determining the Dimer level is considered specific. Its level depends on the presence of pathological conditions that can be accompanied by increased fibrinolysis. These include various types of infections, wound healing, hemorrhagic complications and similar processes. Normally, Dimer does not exceed 33-726 ng/ml. If there are any violations, they must be neutralized without fail. Because the coagulogram norm of this indicator must be fully observed.
Norm of coagulogram PV
The norm of the coagulogram PV is another important indicator. Prothrombin time is an "element" that reflects the speed of blood clotting. It is used to diagnose diseases of the blood coagulation system. In addition, it allows you to evaluate the effect of drugs that are aimed at worsening the ability to coagulate.
Normally, this indicator should not exceed 10-13 seconds. Any deviations indicate the presence of pathological processes in the body. An indicator above the norm indicates that there is a low concentration of coagulation factors, a lack of vitamin K, as well as liver disease or dysfunction.
It is quite possible that we are talking about the presence of disseminated intravascular coagulation syndrome. This condition can be life-threatening, because it does not allow blood to clot quickly, which can lead to complete non-stop bleeding. An increase in prothrombin time is not a good process. If surgical intervention is necessary, the coagulogram norm for this indicator must be observed.
Coagulogram norm during pregnancy
The coagulogram norm during pregnancy must be observed without fail. The fact is that any deviations may indicate serious problems in the body, including early placental abruption, which is extremely unacceptable.
In some cases, it is not so easy to decipher the obtained data. It is advisable to leave this to the doctors. Despite the fact that the indicators can fluctuate significantly during pregnancy, they should not go beyond the permissible limits. Thus, they are as follows: APTT - 17-20 sec; Fibrinogen - up to 6.5 g / l; Lupus anticoagulant - should be absent; Platelets - 131-402 thousand / μl; Prothrombin - 78-142%; Thrombin time - 18-25 sec; D-dimer - 33-726 ng / ml; Antithrombin III - 70-115%.
If the data obtained differs from these figures, it is necessary to take appropriate measures. After all, all this can negatively affect the development of the fetus. Childbirth involves the loss of a small amount of blood. With poor coagulation, this is simply unacceptable. Therefore, the coagulogram norm must be observed.
Coagulogram norm in children
The norm of the coagulogram in children is practically no different from the adult indicators. Thanks to this analysis, it becomes possible to determine the ability of the blood to quickly coagulate. The procedure is not carried out in children very often, mainly only before surgery.
In some cases, the analysis is done even with minor procedures. This will help to avoid all sorts of complications and make sure that the properties of platelets work to the fullest extent. Any deviations can lead to vascular occlusion. Often, a coagulogram is performed if there is a suspicion of blood pathologies.
Normally, the indicators should not go beyond the following limits: APTT - 17-20 sec; Fibrinogen - up to 6.5 g / l; Lupus anticoagulant - should be absent; Platelets - 131-402 thousand / μl; Prothrombin - 78-142%; Thrombin time - 18-25 sec; D-dimer - 33-726 ng / ml; Antithrombin III - 70-115%. Such data are considered standard. The coagulogram norm should fully correspond to the declared indicators.
