Definition

This is a blood test to measure the activity of factor XII -- one of the substances involved in coagulation (blood clotting).

Why is the Test Performed?

To determine the cause of abnormal results on a blood-clotting test (PTT).

Coagulation (blood clotting) results from a sequence of reactions involving proteins known collectively as the coagulation factors. The liver produces coagulation factors and secretes them into the blood.
