Quantitative data published by Booth et al13 for the depression of D, C, and e antigens on SAO erythrocytes. The score numbers are arbitrary values used to quantify the agglutination reaction of normal erythrocytes and ovalocytes, incubated with polyclonal antibodies directed against the respective antigens.
