COAGULATION SCREENING TESTS 1. Prothrombin Time (PT) Measures the extrinsic pathway Prolonged PT FVII deficiency 2. Activated Partial Thromboplastin Time (APTT) Measures the intrinsic pathway Prolonged APTT FXII, XI, IX, VIII deficiency Prolonged PT, APTT FX, F, II, I deficiency 3. Thrombin Time (TT) Measures conversion of I to Ia (fibrin) 4. Reptilase Time (RT) Measures conversion of I to Ia Prolonged TT Abnormal fibrinogen, presence of heparin Prolonged RT Abnormal fibrinogen . 5. Closure Time (with EPI, ADP) Measures platelet number/function Prolonged CEPI, CADP Decreased or dysfunctional platelets
