Both the APTT and PT rely on the final common pathway which follows on from either the intrinsic pathway (in APTT) or extrinsic (in PT). Indeed at therapeutic concentrations PT is within normal range due to a minimal increase. Liver function test normal ranges for blood protein. Liver blood tests are used to check normal, elevated (high), and low blood levels of liver enzymes (AST and ALT or aminotransferases). vitamin K deficiency can also lead to prolonged PT. Reference ranges are the values expected for a healthy person.

The early identification of MI is vital for the institution of anti-thrombotic therapy to limit heart muscle damage and preserve cardiac function. The PTT is a measurement of the intrinsic coagulation pathway and the common coagulation pathway. Incubated mixing studies (in which a mixture of patient plasma and normal pooled plasma is incubated for 1-2 hours at 37°C before testing) are often necessary to detect factor VIII inhibitors, which can develop in patients with hemophilia A.
