PTT Blood Test - More Information

The PTT test, also known as a partial thromboplastin time test, PTT blood test, and PTT lab test, measures the PTT blood level.

PTT (partial thromboplastin time) is a lab test that helps evaluate blood clotting in a part of the clotting pathway known as the intrinsic, or contact activation, pathway. Sometimes known as activated partial thromboplastin time (aPTT), the PTT evaluates factors I, II, V, VIII, IX, X, XI and XII in the coagulation cascade. Elevated aPTT numbers may be seen in the setting of severe infections, hemophilia, heparin use, or the presence of abnormal antibodies generated by the immune system. The PTT test, along with the PT test, is a component of the INR test
