Clinical Significance: Rubella (German Measles) is a common and usually benign viral infection of children. IgM antibody is detectable 11-25 days after the onset of exanthem, in most individuals 15-25 days after vaccination, and in 90-97% of infants with congenital rubella between 2 weeks and 3 months after birth. Acute and convalescent IgG titers may be interpreted to identify a >30% rise in the antibody index. A positive IgG antibody indicates successful immunization or past exposure.

Limitations: False-positives may be found in newborns from mothers. IgM may persist after infection is treated.
