Test Overview
Multiplex Flow Immunoassay
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. Single IgG levels are not useful for supporting the diagnosis of acute infection. Elevated responses in neonates should be followed up with studies to rule out the presence of maternal antibodies, either by obtaining a convalescent specimen or by the demonstration of the absence of an IgM response.
NEGATIVE: No Mumps IgG Antibody detected; POSITIVE: Mumps IgG Antibody detected, indicating previous exposure and immunity to Mumps virus.
* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
Antibody result values from different test methods and/or from different test runs cannot be compared quantitatively. The use of CSF has not been validated by the manufacturer of the current testing system. Timing of specimen collection for paired sera is critical. In some patients, antibody may rise to significant levels and fall again to lower or undetectable levels within a month. Other patients may not develop significant antibody levels.

Specimen Requirements
Collect specimen in SST tube. Centrifuge, aliquot serum into a plastic vial and refrigerate up to 7 days. Post-vaccination samples should be collected 4-6 weeks from the date of vaccination.
Plasma, EDTA or heparinized is acceptable.
Additional Information
Titers will not be reported. Numerical EIA results for single serum specimens do not reflect the magnitude of the measured result above the cut off and are not indicative of the total amount of antibody present. The magnitude of the reported IgG level cannot be correlated to an endpoint titer.
