What is PT?
- Prothrombin time (PT) is a blood test that measures the time it takes for the liquid portion (plasma) of your blood to clot.
- Used in conjuction with INR measurement and comadin (Warfarin)

What is PTT?
- A partial thromboplastin time (PTT) test measures the time it takes for a blood clot to form in a blood sample.
- Used in conjuction with Heparin
What is a normal PTT?
25-30 seconds
