Mumps, IgG Antibody Detection
| Order Code: | MUMP |
| Order Form: | Laboratory Requisition |
Specimen:
Serum
Collection Medium:
![]() |
| Red top tube |
Minimum:
Preferred Minimum: 1 mL serum
Absolute Minimum: 0.1 mL serum
Absolute Minimum: 0.1 mL serum
Rejection Criteria:
Severely icteric, hemolyzed, heat-inactivated, or contaminated
specimens.
Analytic Time:
24 hours upon receipt at reference laboratory
Reference Range:
0.89 IV or less: Negative - No significant level of detectable IgG
mumps virus antibody.
0.90-1.09 IV: Equivocal - Repeat testing in 10-14 days may be helpful.
1.10 IV or greater: Positive - IgG antibody to mumps virus detected, which may indicate a current or past exposure/immunization to mumps virus. Positive IgG antibody levels in the absence of current clinical symptoms may indicate immunity.
0.90-1.09 IV: Equivocal - Repeat testing in 10-14 days may be helpful.
1.10 IV or greater: Positive - IgG antibody to mumps virus detected, which may indicate a current or past exposure/immunization to mumps virus. Positive IgG antibody levels in the absence of current clinical symptoms may indicate immunity.
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.
Comments:
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 acute specimens. Please mark specimens plainly
as "acute" or "convalescent."
