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.

This is a non-fasting blood test that results in 1-2 business days. Please be advised that our services are strictly self-pay and not eligible for submission as a claim to your health insurance provider, medical bill sharing company, Medicare/Medicaid or other third-party payor.  763,8847
