# Prothrombin Time (PT) (Serial Monitor)

> This test measures the number of seconds it takes for your blood plasma to form a clot. It is commonly used to monitor the effectiveness of blood-thinning medications or to investigate symptoms like unexplained bleeding and bruising. By checking how quickly your blood clots, this test helps doctors rule out bleeding disorders or liver problems. However, it cannot identify the specific underlying cause of a clotting issue by itself and is often reviewed alongside other blood tests.
