A coagulation profile, also known as a coagulation panel, is a series of blood tests that evaluate the blood's ability to clot. The profile typically includes tests such as Prothrombin Time (PT), Activated Partial Thromboplastin Time (aPTT), Fibrinogen Level, and Platelet Count. These tests are essential in diagnosing bleeding disorders, monitoring anticoagulant therapy, and assessing the risk of hemorrhage during surgeries.
