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.
