The technique of the hemagglutination inhibition test as used in the Robert Koch-Institute for the demonstration of rubella antibody is described. This technique enables the examination of a great number of sera within a short time while having a minor expenditure of material. The method was used to examine for rubella antibody 756 sera from test persons of both sexes and various age groups. In neonates and infants up to the 30th day of life, diaplacentally transmitted antibody could be demonstrated in 94 of cases. In the course of the first year of life, the rate of positive sera will fall to 11 and rise again, gradually, for the age groups that follow. For age 20 and over, rubella antibodies are demonstrable in 92-97 of the sera examined.
