PURPOSE: To obtain a method for measuring completely automated accurate function of von Willebrand factor by the platelet sedimenting velocity measurement in the presence of ristocetin capable of being applied to a centrifuge analyzer. CONSTITUTION: The method for measuring von Willebrand factor comprises the steps of incubating biological material such as, for example, specimen of plasma together with reagent containing platelet and ristocetin, and measuring aggregation degree by the turbidity change. The formed aggregate is sedimented as regulated by the suitable radial acceleration during the centrifuge. |
