This test measures how long it takes for blood to clot. It includes the Prothrombin Time (PT), International Normalized Ratio (INR), and Partial Thromboplastin Time (PTT). These components help assess the clotting ability and detect potential bleeding disorders.

What it measures

Prothrombin Time (PT) — reflects how quickly blood clots
International Normalized Ratio (INR) — standardizes PT results
Partial Thromboplastin Time (PTT) — evaluates intrinsic clotting pathway

What the test involves

The test involves a standard blood draw from a vein in your arm. The blood sample is then analyzed in a laboratory.

Why it is often ordered

Clinicians typically order this test to evaluate bleeding disorders or monitor blood-thinning medications. It helps in assessing the risk of abnormal bleeding or clotting.

Preparation

Preparation instructions may vary, so it's important to follow the lab's specific guidelines. Some medications may need to be paused before the test.

How results are reported
