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.
