PT, PTT

Item Catalog Number: LC020321

Doctors like to check coagulation profiles which include PT and PTT. PT stands for Prothrombin time and PTT stands for Partial Thromboplastin Time. They are measurements of how quickly a blood clot forms. These tests may be ordered when people present with unexplained bleeding or bruising or with chronic conditions such as liver disease or lupus.

This test also contains an INR (International Normalized Ratio) for those people taking Coumadin. Doctors use an INR to assess the effect of the drug.

Fasting is not required. Take all medications as prescribed. Do not take supplements the day of the test.
