Coagulation Screen - Basic (PT, INR, aPTT)

Coagulation Screen - Basic (PT, INR, aPTT) is a group of blood tests that provides essential information about the clotting ability of your blood. The Prothrombin Time (PT), International Normalized Ratio (INR), and Activated Partial Thromboplastin Time (aPTT) are part of the basic coagulation panel. These tests are often used to diagnose bleeding disorders, to monitor the effectiveness of certain medication treatments, or to prepare for surgical procedures.
