Prothrombin Time Test in Station Road, Bandikui

A Prothrombin Time (PT) Test is a blood test that measures how long your blood takes to clot. It helps doctors evaluate bleeding disorders, liver function, vitamin K deficiency, and monitor blood-thinning medicines like warfarin

Doctors usually recommend a PT/INR test to monitor anticoagulant therapy, investigate unusual bleeding or bruising, check clotting disorders, or before surgeries and medical procedures.

Fasting is generally not mandatory for a PT test, although overnight fasting may sometimes be preferred. Patients should also inform the doctor about any blood-thinning medicines or supplements they are taking.

The normal Prothrombin Time range is usually around 10–13 seconds, while a normal INR for people not on anticoagulants is typically 0.8–1.2. The target INR may be higher for patients taking blood thinners.

A high PT/INR may indicate liver disease, vitamin K deficiency, clotting disorders, or the effect of anticoagulant medications. It means the blood is taking longer than normal to clot.

The PT test requires a small blood sample, usually collected from a vein in the arm. The sample is then tested in the laboratory to measure clotting time and calculate INR values.

PT test reports are generally available within a few hours, depending on the laboratory and sample processing time. At Dr. B. Lal Lab, results are typically available within 5 hours.
