Specimen Required

Patient Preparation

Serum Separator Tube (SST).

Allow specimen to clot completely at room temperature. Separate from cells ASAP or within 2 hours of collection. Transfer 1 mL serum to an ARUP Standard Transport Tube. (Min: 0.5 mL) Parallel testing is preferred and convalescent specimens must be received within 30 days from receipt of acute specimens.

Storage/Transport Temperature

Contaminated, heat-inactivated, grossly hemolyzed, lipemic, or severely icteric specimens.


Label specimens plainly as acute or convalescent.

Semi-Quantitative Chemiluminescent Immunoassay




Within 24 hours

Reference Interval

Effective August 20, 2012

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.
