Reference Range
0.79 IV or less: Negative - No significant level of
detectable IgM antibody to Mumps virus
0.80 - 1.20 IV: Equivocal - Borderline levels of IgM
antibody to Mumps virus. Repeat testing in
10 - 14 days may be helpful.
1.21 IV or greater: Positive - Presence of IgM antibody
to Mumps virus detected, which may indicate a
current or recent infection.
However, low levels of IgM antibody may occasionally
persist for more than 12 months post-infection
or immunization.
