<prompt> Bleeding time is done to assess:Platelet functionIntrinsic pathwayExtrinsic pathwayCoagulation cascade  <response>: Ans: a Platelet function Ref: O.P. Ghai 6th ed,p. 322-23Bleeding time is prolonged in all conditions associated with thrombocytopenia and platelet function defects.Here it will be better if you go through the diagnostic approach to bleeding disorders given in O.P. Ghai.Clotting time increasedCoagulation defect.Prothrombin timeIndicator of extrinsic pathway of coagulation factor VIIActivated partial thromboplastin time indicator of intrinsic pathway of coagulation VIII, IX, XI, XIIClot stability with 5 M urea-factor XIII deficiency. All other tests are normalBoth PT and APTT increasedCommon pathway defect, liver dysfunction, DIC, vit.K deficiency. V, X, fibrinogen deficiencyIn DIC, thrombin time also prolonged.
