Partial Thromboplastin Time (PTT), Activated AND Prothrombin Time (PT)
The prothrombin time (PT) test measures how long it takes for a clot to form in a sample of blood.
The PTT test is ordered when someone has unexplained bleeding or clotting. Along with the PT (which evaluates the extrinsic and common pathways of the coagulation cascade), the PTT is often used as a starting place when investigating the cause of a bleeding.
Preparation: No special preparation is needed. Fasting is not required for this blood test. In general, being well hydrated (drinking plenty of water before the blood draw) will help make your veins somewhat easier to locate and access for the blood draw.
