What is Activated Partial Thromboplastin Time (aPTT)?
The Activated Partial Thromboplastin Time (aPTT) is a blood test used to measure the time it takes for blood to clot. It is a crucial diagnostic tool in assessing the functionality of the intrinsic pathway and the common pathway of the coagulation cascade. The aPTT test is frequently used to monitor patients on heparin therapy and to identify potential bleeding disorders.
