An Activated Partial Thromboplastin Time (APTT or aPTT) test measures the time it takes for your blood to form a clot. While the PT/INR test (which you asked about earlier) looks at the “Extrinsic” pathway, the APTT focuses on the Intrinsic and Common pathways of coagulation.
This is the primary test used to monitor patients on Heparin therapy and to screen for hemophilia or other bleeding disorders.
