Abnormal PT values may indicate liver disease, vitamin K deficiency, or the presence of anticoagulants. Partial Thromboplastin Time
Prothrombin Time Test (PT) and INR What does the test result mean? The normal PT range is 11 to 14 seconds. The normal range may vary slightly from lab to lab. Normal ranges are usually shown next to your results in the lab report. A PT value [higher than normal] means your blood is taking longer than usual to form a clot. This prolonged PT may
