Quick View
A prothrombin time (PT) is a test used to detect and diagnose a bleeding disorder or excessive clotting disorder. The international normalized ratio (INR) is calculated from a PT result and is used to monitor how well an anticoagulant is working to prevent blood clots.
When there is prolonged bleeding or inappropriate clotting disorder, when there is intake of warfarin.
1. Other than warfarin, what causes prolonged prthrombin time?
Vitamin K deficiency, Liver disease, Hematocrit >55%, Disseminated intravascular coagulopathy, Dysfibrinogenemia, deficiency of extrinsic clotting factor deficiencies (factors II, V, VII, X, fibrinogen), thrombin and factor X inhibitors, gross lipemia of sample, elevated bilirubin, lupus anticoagulants etc, will prolong the prothrombin time.
2. Is the Prothrombin time-INR useful for patients with liver disease?
In persons with a stable chronic liver disease, the Prothrombin time-INR is generally increased (as the clotting factors production is decreased). But if the disease is unstable, the Prothrombin time-INR will not be reliable.
