Hemostasis system is a biological system of the body, the main function of which is to preserve the liquid state of the blood, the formation of blood clots and their subsequent dissolution. The study of the components of the hemostasiogram allows us to evaluate the interaction of the coagulation and anticoagulation functions of the blood. Evaluation of Hemostasis are in demand in cardiology, phlebology, surgery, obstetrics and neonatology. They are carried out in combination with a general blood test. The results of the hemostasiogram are used to diagnose and monitor the effectiveness of therapy for hemophilia, thrombosis, DIC syndrome, pregnancy complications, as well as other diseases accompanied by bleeding or increased blood clots. The material for analysis is venous blood serum. The studies are performed by coagulometric methods, the preparation of the results takes from 1 to 7 days.
Antithrombin III -protein that inactivates blood clotting factors, including thrombin, and prevents excessive formation of blood clots. Quantitative and qualitative studies of antithrombin III in the blood are performed within the framework of a coagulogram, the interpretation of the indicator is often made taking into account the results of tests for protein C, protein S…
D-Dimer is a protein fragment formed during the dissolution of a blood clot, the level of which in the blood plasma reflects the activity of the processes of thrombosis and fibrinolysis. D-dimer test is used as an auxiliary test, and the diagnosis is determined taking into account the clinical signs and the results of a comprehensive…
PTT (activated partial thromboplastin time) is the rate of formation of a blood clot in a plasma sample after adding calcium chloride and other reagents to it. This indicator is determined as part of the study of the hemostasis system and reflects the characteristics of the internal pathway and the general cascade of the coagulation…
Coagulation tests – method of complex investigation of the hemostasis system. Coagulation tests may include a set of various indicators, the main of which are prothrombin time, thrombin time, clotting time, fibrinogen, antithrombin III, lupus anticoagulant, APTT, D-dimer, prothrombin index, etc. Coagulation tests in cardiology has diagnostic value in myocardial infarction, assessment of the risk of bleeding,…
