Rubella Antibodies (IgG, IgM) Diagnostic
Also known as: German Measles
Use
Rubella (German Measles) is a common and often benign viral infection, particularly in children. Detection of rubella-specific IgM antibodies typically indicates recent or acute infection, while IgG antibodies suggest past infection or successful immunization. In congenital cases, IgM is detectable between 2 weeks and 3 months of age; measuring acute and convalescent IgG titers can help identify rising antibody levels indicative of recent exposure or vaccination ([jdos.nicholsinstitute.com](https://jdos.nicholsinstitute.com/dos/nmmcpathology/test/572140?utm_source=openai)).

Limitations
False-positive IgM results may occur in newborns due to maternal antibodies; additionally, IgM may remain detectable even after successful treatment, potentially complicating interpretation ([jdos.nicholsinstitute.com](https://jdos.nicholsinstitute.com/dos/nmmcpathology/test/572140?utm_source=openai)).
