Clinical Significance

The IgG antibody test for mumps may be ordered to determine immune status due to infection, vaccination, or an outbreak. IgM or PCR testing should be considered for suspected infection. The first type of antibody to appear after exposure or vaccination is IgM antibodies. Levels of IgM antibodies increase for several days to a maximum level and then begin to taper off over the next few weeks. IgG antibodies take a bit longer to develop, but once they do, they stay positive for life, providing protection against re-infection.

Testing of two samples obtained weeks apart can be used to differentiate between an active (acute) and prior (convalescent) infection.

Signs and symptoms of mumps typically develop after a 2 to 3 week incubation period and often resemble symptoms of the flu followed by characteristic swelling of the salivary glands below one or both ears (parotitis).
