title: A rubella haemagglutination inhibition test not requiring removal of non-specific inhibitors. 1. Elaboration of the test.
abstract: The rubella haemagglutination inhibition (HI) test can be simplified and the probelm of non-specific inhibitors circumvented by allowing the haemagglutinin to react with erythrocytes before addition of the serum specimen. The elaboration of the test procedure is described, and preliminary studies indicate that the new method may prove useful both in the diagnosis of rubella infection and for determination of immunity status.
