Three tests are recommended for use in initial screening for possible bleeding disorders: activated partial thromboplastin time (aPTT),prothrombin time (PT),and platelet count.The Ivy bleeding time (BT)has been used to screen for disorders of platelet function and thrombocytopenia.It has been found to be unreliable and is no longer used as a screening test.The platelet function analyzer (PFA-100)is more sensitive and specific for platelet disorders and von Willebrand disease (vWD)than the bleeding time; however,it is not sensitive enough to rule out underlying mild bleeding disorders.Also,it has not been evaluated prospectively to determine its utility in predicting bleeding risk,although studies are under way.Therefore,the BT and PFA-100 are not recommended as screening tests to be used by the dentist.
