Ristocetin cofactor (RCoF) assay is used to evaluate VWF activity, but it does not assess collagen\u2010binding activity. Normal values of RCoF and VWF antigen vary with ABO blood group type. The collagen\u2010binding assay (CBA) measures VWF activity; however, its relationship with ABO blood group has not been completely explored. We performed CBA on plasma samples from 131 healthy volunteers to determine if CBA values correlated with blood type. Individuals with blood group O had a mean CBA value of 94 \u00b1 28%, which was significantly different from the mean of 117 \u00b1 33% in persons with non\u2010O blood groups (<jats:italic>P<\/jats:italic> = 0.0001). Thus, CBA values appear to correlate with ABO blood type in a manner similar to RCoF. Am. J.
