VWF:Ag values are expressed as mean ± SD.

For both phenotypes, VWF:Ag increased according to ABO blood group in the order O < A < B < AB. Mean VWF:Ag was significantly lower in group O and group A heterozygotes than in the respective homozygotes, and the overall mean for heterozygotes was significantly lower than for homozygotes.
