Reference Range:
Reference range and methodology changed effective 12/11/2012.

0.8 AI or less: Negative - No significant level of detectable mumps IgG antibody.

0.9-1.0 AI: Equivocal - Repeat testing in 10-14 days may be helpful.

1.1 AI or greater: Positive - IgG antibody to mumps detected, which may indicate a current or past exposure/immunization to mumps.
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.

Mumps IgG antibody can be formed following mumps infection or after mumps vaccination. A reactive result is consistent with immune status to mumps virus. Non-reactive and equivocal results flag as abnormal in Epic which indicates non-immune or equivocal immune status to mumps. A non-reactive result does NOT imply mumps infection. If ordered in workup of possible mumps infection, the IgG antibody results should be interpreted in conjunction with other laboratory tests, clinical history, and physical examination.
Comments:
Indicate whether specimen is "ACUTE", "CONVALESCENT" or "RANDOM." RANDOM would be appropriate selection if the test is ordered to determine patient immunity status for mumps (e.g., for student or employee health).

For workup related to possible mumps infection, acute and convalescent specimens must be labeled as such; parallel testing is preferred and convalescent specimens must be received within 30 days from receipt of the acute specimens. Please mark specimen plainly as "ACUTE" or "CONVALESCENT."
