Measles (Rubeola) Antibodies, IgM, Serum
Use
This test is useful for determining acute-phase infection with the measles virus through the detection of IgM antibodies. It aids in identifying individuals who are not immune to the virus. The presence of IgM antibodies indicates recent infection, but results should be interpreted in conjunction with clinical findings as IgM results alone should not be used to diagnose measles infection.
Special Instructions
Not provided.
Limitations
Specimens must not be hemolyzed, hyperlipemic, or icteric, as these conditions can yield unreliable results. Serum specimens should not be heat-inactivated prior to testing. Results may be negative in the early phase of infection when antibody titers are low. Heterotypic responses with rubella and varicella viruses can occur.
