    Reference Range
    Ref. Range Notes

    Reference Values:

    Negative: Index value 0.00-0.79

    Reference value applies to all ages.

    Interpretation:

    Positive: Presence of IgM-class antibodies to mumps virus may support a clinical diagnosis of recent or acute phase infection with this virus.
    Negative: Absence of IgM-class antibodies to mumps virus suggests lack of acute phase infection with mumps virus. However, serology may be negative in early disease, and results should be interpreted in the context of clinical findings.
    Interferences and Limitations

    Cautions:

    Results must always be interpreted together with other clinical and laboratory findings.

    Serum specimens drawn during the acute phase of infection may be negative by serological tests.

    All positive results must be interpreted with care, as some false-positive results or heterotypical responses of the IgM have been seen in the serum of pregnant women or in patients with an acute infection caused by cytomegalovirus, herpes simplex virus, measles, rubella, and parvovirus.
