8.9 AU/mL or less: Negative - No significant level of detectable IgG mumps virus antibody.
9.0-10.9 AU/mL: Equivocal - Repeat testing in 10-14 days may be helpful.
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
The best evidence for current infection is a significant change on two appropriately timed specimens, where both tests are done in the same laboratory at the same time.
