WebFeb 15, 1990 · The binding of vWf to collagen has been well described (12 - 16). Brown and Bosak described a procedure for quantitating vWf binding to collagen (8). Their results indicated this test to be a reasonable alternative to the RCof assay. Both assays appear to measure the high molecular weight portion of the vWf multimer complex (8). Web(2) The ristocetin cofactor (RCoF) assay measures VWF functional activity in plasma. Ristocetin promotes the binding of large VWF multimers from plasma onto formalin-fixed …

WebJun 1, 2009 · The RCof assay using a standardized formalin-fixed platelet reagent serves this purpose better. The PFA-100 also can test overall GPIbα/vWF-mediated platelet function using a far more convenient procedure. Where the RIPA is most useful is in the evaluation of agglutination in the presence of low doses of ristocetin (≤ 0.5 mg/mL versus 1.0 ... WebThe RIPA assay tests the capacity of VWF to agglutinate platelets with varying concentrations of ristocetin. In contrast to the VWF : RCo (which evaluates the interaction between the patient's VWF and formalin-fixed platelets), the low dose RIPA assay evaluates the sensitivity of the patient's platelets to low-dose ristocetin. can 16 year old go to gym

WebThree separate laboratory assays for VWF were performed; (i) a standard ‘antigen’ (antisera-ELISA-based) assay (VWF:Ag), (ii) a standard ristocetin-dependent-platelet-agglutination procedure (VWF:RCof) and (iii) a more recently described ELISA-based functional collagen-VWF binding assay (VWF:CBA). WebRcoF is the most sensitive and specific test for von Willebrand’s disease, and is decreased in virtually all types of the disease.
