Sensitive hemagglutination inhibition test for mumps antibody

Abstract

Incorporation of heterologous immunoglobulin against human immunoglobulin G into the mumps HI tests provided a highly sensitive and specific way of measuring mumps antibody in human sera. The sensitivity of this enhanced mumps HI test compared favorably with that of an anti-immunoglobulin-enhanced virus plaque neutralization test, but the HI test required considerably less time and effort to perform.
