The participation of platelets in the intrinsic pathway of blood coagulation is known as “platelet factor - 3” (PF-3), but - as has been emphasized by Marcus (12) - this is not a true “factor” rather an activity of the plasma membrane of the platelet. The membranes of “activated” platelets probably supply a catalytic lipoprotein surface for the interaction of plasma coagulation factors (8).
