Why This Biomarker Matters

These tests detect bleeding or clotting disorders and monitor anticoagulant medications. Abnormal results can indicate serious conditions requiring treatment to prevent dangerous bleeding or clots.

Overview

The PT (prothrombin time) and aPTT (activated partial thromboplastin time) panel measures how quickly your blood clots. PT evaluates one clotting pathway, while aPTT evaluates another; together they assess your blood's overall ability to form clots. These tests are essential before surgery, for monitoring blood-thinning medications like warfarin or heparin, and for diagnosing bleeding or clotting disorders. Abnormal results may indicate liver disease, vitamin K deficiency, or inherited clotting disorders.
