Coagulation profile is a laboratory test that detects coagulation system indicators. Coagulation profile includes the following indicators:

• APTT - This is the period of time for which a blood clot is formed.
• Fibrinogen - This is a protein produced in the liver that is converted into fibrin, which is the basis of the clot during blood clotting. Subsequently, fibrin forms a clot, which eventually completes the blood clotting process.
• Thrombin time - shows the time of formation of fibrin from its precursor fibrinogen.
• Prothrombin time with determination of PTI and INR. - time for which a blood clot is formed by specific clotting factors, which are formed after damage to the tissues of the body. PTI is the index of the clotting time of control ("normal") plasma to the clotting time of the patient's plasma. This index reflects the processes of activation of the external pathway of coagulation. INR.

The practical application of this test is to control the amount of blood thinning medications taken. Thus, it is necessary to select the right dose of the medication.
