What is Activated Partial Thromboplastin Time (aPTT)?
Activated Partial Thromboplastin Time (aPTT) is a blood test that measures the time it takes for blood to clot. It is often used to assess the intrinsic and common pathways of coagulation. This test is crucial in monitoring patients who are on anticoagulant therapy such as heparin, and in diagnosing bleeding disorders.
