Reference Range
Measles IgG (AU/mL):
<13.50 Not consistent with immunity
13.50 – 16.49 Equivocal
>16.49 Consistent with immunity
The presence of measles IgG suggests immunization or past or current infection with measles virus.
<13.50 Not consistent with immunity
13.50 – 16.49 Equivocal
>16.49 Consistent with immunity
The presence of measles IgG suggests immunization or past or current infection with measles virus.
Clinical Significance
Measles, also known as rubeola, causes fever, irritability, respiratory illness, and the characteristic skin rash. Immunization has greatly diminished the incidence of measles. The presence of IgG is consistent with immunity or prior exposure. IgM is consistent with current or recent infection. IgM tests can generate false positive results and low levels of IgM can persist for longer than 12 months.
