The presence of detectable IgG-class antibodies indicates prior exposure to the mumps virus through infection or immunization. Individuals testing positive are considered immune to the mumps virus. Equivocal:

The presence of mumps IgG antibody suggests immunization or past or current infection with mumps virus. The presence of IgM antibody to mumps typically indicates recent or current mumps infection; however, false positive results may occur due to antibody cross reactivity to parainfluenza virus. Mumps Evaluation.

Jun 5, 2024 · The presence of mumps-specific IgG indicates a recent or a prior exposure to mumps virus or mumps vaccine. Serologic tests cannot differentiate between an exposure to vaccine and an exposure to wild-type mumps virus.

What is Mumps Virus Antibody IgG Test? Mumps-virus-antibody-IgG test is used to determine whether a person has antibody that protects glands, measles and mumps antibodies. Measles and mumps antibodies are virus-specific proteins produced by the immune system in response to an infection by the measles or mumps virus, or in response to vaccination.

Jun 11, 2024 · The availability of assays to detect IgM (to aid in the diagnosis of acute mumps infection) and to measure IgG antibodies (to document previous exposure to mumps) varies among laboratories. Your state health department can provide guidance regarding available laboratory services in your state.

Widespread immunization of infants with attenuated mumps virus has significantly reduced reported cases in the United States, but outbreaks still occur, suggesting the virus persists in the population. Laboratory diagnosis typically involves detecting IgM- and IgG-class antibodies to …

11.0 AU/mL or greater: Positive - IgG antibody to mumps virus detected, which may indicate a current or past exposure/immunization to mumps virus. Interpretive Data May include disease information, patient result explanation, recommendations, or details of testing.

Laboratory diagnosis of mumps is typically accomplished by detection of IgM- and IgG-class antibodies to the mumps virus. However, due to the widespread mumps vaccination program, in clinically suspected cases of acute mumps infection, serologic testing should be supplemented with virus isolation in culture or detection of viral nucleic acid by ...

Support the diagnosis of Mumps infection. The presence of IgG antibody generally indicates past exposure and immunity. The presence of IgM antibody or a fourfold or greater rise in IgG antibodies in paired sera indicates recent infection.

A negative IgG result coupled with a negative IgM result indicates the absence of prior exposure to mumps virus and nonimmunity. However, a negative result does not rule-out mumps infection or response to vaccination.
