The Prothrombin Time (PT) test is a blood test that measures the time it takes for blood to clot. It helps evaluate the blood clotting ability and is used to assess liver function, bleeding disorders, and the effects of blood-thinning medications.
Indications for PT Test:
● Blood clotting problems: If you have unexplained bleeding or bruising, this test helps evaluate clotting function.
● Liver diseases: The test can be used to assess liver function in conditions like cirrhosis or hepatitis.
● Monitoring anticoagulant therapy: For patients on blood thinners like warfarin, PT is used to monitor the therapeutic effect and ensure safety.
How PT Test Works:
● A blood sample is taken and the time it takes for the blood to clot is measured. The results are usually given in seconds and are compared to normal values.
Normal Range:
● PT normal range: Usually between 10–13 seconds, but this can vary depending on the laboratory.
Abnormal Test Significance:
● Prolonged PT: Can indicate liver disease, vitamin K deficiency, or bleeding disorders like hemophilia.
● Shortened PT: Could suggest a hypercoagulable state where the blood clots too quickly, increasing the risk of thrombosis.
Management Based on Results:
● For prolonged PT: Vitamin K injections, anticoagulants, or blood transfusions may be required depending on the underlying cause.
● For abnormal clotting: Adjustments in anticoagulant therapy or further investigation into clotting disorders may be needed.
Price in India:
Approx. ₹200 – ₹700 for PT testing.
