VI. Coagulation:

  • Prothrombin Time (PT): 10 – 14 seconds
  • Activated Partial Thromboplastin Time (APTT): 24 – 37 second
  • Fibrinogen: 1.50 – 4.50 g/L
  • D-Dimer: < 500 ng/Ml:
    • Fibrin degradation product (FDP), protein fragment present in the blood after blood clot is degraded by fibrinolysis
    • used to Exclude thromboembolism, and
    • Diagnose DIC
    • 4 fold increase is an indicator of mortality in COVID-19

An INR range of 2.0 to 3.0 is generally an effective therapeutic range for people taking warfarin for disorders such as atrial fibrillation or a blood clot

The normal range for your PT results is: 11 to 13.5 seconds. INR of 0.8 to 1.1. PTT: 30 to 45 seconds.
