ABSTRACT:
In the rubella virus hemagglutination-inhibition test, the hemagglutination-inhibition antibody titers of the test sera can be determined with accuracy and high sensitivity by employing a novel diluent, which contains N-2-hydroxyethylpiperazine-N'-2'-ethanesulfonic acid in a low concentration and which is free from calcium ion, for the dilution of the rubella virus hemagglutinating antigen and of the test sera.
