What is the BT CT PT INR Test?

The BT CT PT INR test is a group of coagulation tests (blood clotting tests) that evaluate how well your blood clots. These tests are essential for pre-surgical evaluation, diagnosing bleeding disorders, and monitoring patients on anticoagulant therapy (blood thinners like warfarin).

BT — Bleeding Time

Measures how long it takes for bleeding to stop after a small puncture. Tests platelet function and vascular integrity. Normal: 1-6 minutes.

CT — Clotting Time

Measures how long it takes for blood to form a clot in a test tube. Evaluates the intrinsic coagulation pathway. Normal: 4-10 minutes.

PT — Prothrombin Time

Measures time for blood to clot via the extrinsic pathway. Used to assess liver function and monitor warfarin therapy. Normal: 11-13.5 seconds.

INR — International Normalized Ratio

Standardized ratio of PT results for consistent comparison across labs. Normal: 0.8-1.2 (healthy), 2.0-3.0 (on warfarin). Critical for dose adjustment.

Frequently Asked Questions — BT CT PT INR Test

BT CT PT INR is a group of coagulation tests that measure how quickly your blood clots. BT (Bleeding Time) measures how long it takes for bleeding to stop. CT (Clotting Time) measures how long it takes blood to clot. PT (Prothrombin Time) measures the time for blood to clot via the extrinsic pathway. INR (International Normalized Ratio) standardizes PT results for comparison. These tests are essential before any surgery, to diagnose bleeding disorders, and to monitor anticoagulant therapy.
The BT CT PT INR test is done for: pre-surgical evaluation (mandatory before any surgery), monitoring warfarin/blood thinner dosage, diagnosing bleeding disorders like hemophilia, evaluating liver function (as the liver produces clotting factors), investigating unexplained bleeding or bruising, and assessing risk of excessive bleeding or clotting.
The BT CT PT INR test is available at affordable prices at Anubhav Life Care Barasat. We offer transparent pricing with no hidden charges. Contact us at +91-9230755875 for current rates. Free home collection is available within 10 km.

Normal ranges: Bleeding Time (BT): 1-6 minutes. Clotting Time (CT): 4-10 minutes. Prothrombin Time (PT): 11-13.5 seconds. INR: 0.8-1.2 for healthy individuals, 2.0-3.0 for patients on warfarin therapy. Values outside these ranges may indicate bleeding or clotting disorders.
At Anubhav Life Care, BT CT PT INR test results are typically available within 6 hours. Our NABL-accredited lab uses fully automated coagulation analyzers for accurate and fast results. Reports are delivered via WhatsApp for convenience.

An INR above 1.2 in a non-medicated person may indicate liver disease, vitamin K deficiency, or a clotting factor deficiency. An INR below 2.0 in a warfarin patient means insufficient anticoagulation (risk of clots). An INR above 3.0 means over-anticoagulation (risk of bleeding). Your doctor will adjust medication based on INR values.
