we have studied three afibrinogenemic patients , who had only trace amounts of plasma and platelet fibrinogen as measured by radioimmunoassay , and demonstrate here that the residual aggregation observed in their platelet-rich plasma is dependent upon von willebrand factor ( vwf ) binding to the platelet membrane glycoprotein ( gp ) iib/iiia complex .
