Comments		A positive result indicates the presence of detectable mumps virus IgG antibodies. A positive result generally indicates past exposure to mumps virus or previous vaccination. Measles and Mumps IgG antibody testing may be used to provide laboratory evidence of immunity in individuals without documented MMR vaccination or prior infection. An equivocal result should be followed by collection of a second sample no less than one to two weeks later. A negative result indicates the absence of detectable mumps virus IgG antibodies. A negative result generally indicates that the patient has not been infected and is susceptible to mumps. This interpretation depends on the history of mumps or mumps vaccination. If the subject has no history of mumps, has not been previously vaccinated and exposure to mumps virus is suspected despite a negative finding, a second sample should be collected and tested no less than one to two weeks later.
