Explanation coagulation assays

Coagulation or hemostasiogram, to evaluate the process of blood clotting in the body.

For decoding of coagulation test results using indicators:

  • blood coagulation: the norm - 5-10 minutes from a vein from the capillary - the beginning of 0.5-2 minutes, the end of 3-5 minutes;
  • bleeding time (VC): the rate - 2-3 minutes (the finger);
  • Adhesion - the platelets adhere to the vessel wall is damaged: the rate - 20-50%;
  • prothrombin time - during the final stage of blood coagulation: the norm - 11-16 seconds;
  • prothrombin ratio - the ratio of the clotting time of the patient's plasma and control plasma: the norm - 78-140%;
  • prothrombin - a protein that provides coagulation: the norm - 78-142%;
  • fibrinogen - a liver protein that can be transformed into fibrin required for thrombus formation: the rate - 2-4 g / l;
  • aggregation - platelet compounds: the norm - 0-20%;
  • activated partial thromboplastin time (APTT) - period of time when a blood clot forms: the norm - 24-35 seconds;
  • lupus anticoagulant - immune antibodies that resist phospholipids forming clots: rate - 0.6-1.2 US dollars;
  • calcium clotting plasma: the norm - 60-120 seconds;
  • retraction of a blood clot - the allocation of serum from clot: the rate - 44-65%.

This shows coagulation:

  • pregnant - once a term;
  • patients before and after surgery;
  • patients with autoimmune diseases;
  • with venous varices;
  • liver disease;
  • with pathologies systems: endocrine, circulatory, cardiovascular, urinary;
  • for miscarriage, infertility;
  • with frequent bleeding from the gums, nose.

Terms of delivery of blood coagulation analysis:

  • blood is taken from a vein;
  • on an empty stomach in the morning, only to drink water;
  • should tell the technician about taking medication.

Assign an analysis surgery, gynecology, infectious disease specialist, internist, ENT, endocrinologist.
