title: Absence of platelet activating factor (PAF) mediated platelet aggregation: a new platelet defect.
abstract: The failure of normal human platelets to aggregate in response to platelet activating factor (PAF) has not been previously observed. We report here the first case of a patient whose platelets did not aggregate to PAF on multiple occasions.
