    • - Screens for deficiencies & inhibitors of all clotting factors except VII & XIII.
    • -Used to monitor Heparin Thearapy and Coagulation disorders.
  6. PT (Prothrombin Time) - MALE
    • 9.6 - 11.8 seconds
    • -Measures the amount of time it takes for clot formation.
    • -Used to monitor warfarin sodium (Coumadin) Therapy, screen for disfunction of the extrinsic system that results from liver disease, Vitamin K deficiency, or Disseminated Intravascular Coagulation (DIC).
