The preoperative screening, however, is limited, in a majority of institutions, to the collection of a personal history and to the performance of a clotting time and a bleeding time by the Duke method. The dangers of this approach have been emphasized from several sources.1,2

Cases, however, in which a bleeding tendency may exist unknown are, as a rule, borderline situations reflecting platelet defects or moderate deficiency of factors involved in the first phase of the blood clotting process. These patients may not exhibit significant spontaneous bleeding (although they may bleed freely in the event of surgery), and their history may be vague and equivocal.
