Abnormal Values
0 parameters
PT Status1 (1=Normal, 2=Elevated)
INR Status2 (1=Low, 2=Normal, 3=Therapeutic, 4=High)
PTT Status1 (1=Normal, 2=Elevated)
How to Use This Calculator
- Enter PT (prothrombin time in seconds) and the laboratory's normal mean PT to calculate INR.
- Input aPTT (activated partial thromboplastin time in seconds) and the laboratory reference range.
- Enter fibrinogen level (mg/dL) if available.
- Review INR, aPTT ratio, and fibrinogen interpretation for bleeding or clotting risk.
- Monitor trends over serial draws for patients on anticoagulation therapy.
