Partial thromboplastin time

The partial thromboplastin time (PTT), also known as the activated partial thromboplastin time (aPTT or APTT), is a blood test that characterizes coagulation of the blood. A historical name for this measure is the Kaolin-cephalin clotting time (KCCT), reflecting kaolin and cephalin as materials historically used in the test.
