title: Determination of ABH secretor status by an electronic quantitation method.
abstract: Blood Group A and B substances in secretor (Se) and nonsecretor (se) salivas were tested by means of an electronic data processing-hemagglutinin-inhibition test (EDP-HAIT) with immunoglobulin M (IgM) isohemagglutinins. Besides a difference in quantity, the blood group substances in Se saliva showed high binding efficiencies compared with those in se saliva. EDP-HAIT with IgG isohemagglutinins proved no difference in the binding efficiencies of Se and se salivas. The determination of secretor status by EDP-HAIT with IgM isohemagglutinin was accurate because the conclusion was obtained based on two different quantitative results. Secretor status of some salivas in gargled water could be determined by comparing the binding efficiencies.
