WebMay 24, 2016 · Prolonged PT indicates deficiency of FVII, FX, FV, FII and Fibrinogen. As there is variability among individual laboratory reagents, PT test is reported commonly along with its INR (International Normalised Ratio). A normal coagulation profile is reported as an INR of 1.0. Prothrombin Time is prolonged in: 1. WebPhospholin ES is intended for use as an activated partial thromboplastin time (APTT) reagent. The APTT test is a qualitative assay used in routine coagulation screening of patient plasma to detect deficiencies in the intrinsic pathway. It is also used to monitor heparin therapy and in the detection of Lupus Anticoagulants.
