If PT, aPTT, and platelet count are normal in a patient with a history of mucocutaneous bleeding, then primary hemostasis should be investigated (eg, with the platelet function analyzer PFA-100 [Dade Behring, Inc, Deerfield, Ill], which can also screen for vWD). However it cannot monitor therapy with newer "low molecular weight heparin" (LMWH). A similar but more subtle problem might arise if the patient's hematocrit is unusually high, typically ≥55%.
