rubella HI test


Definition: a hemagglutination inhibition (HI) test for rubella, often performed routinely as part of a prenatal workup of the pregnant woman; the presence of a detectable HI titer in the absence of disease indicates previous infection and immunity to reinfection; if HI antibody is undetected, the patient is considered potentially susceptible and is observed accordingly during follow-up.
