Reference Range:
7 IU/mL or less: Negative - No significant level of detectable rubella IgG antibody. 8-9 IU/mL: Equivocal - Repeat testing in 10-14 days may be helpful. 10 IU/mL or greater: Positive - IgG antibody to rubella detected, which may indicate a current or previous exposure/immunization to rubella. Rubella IgG antibody can be formed following rubella infection or after rubella vaccination. A reactive result is consistent with immune status to rubella virus. Non-reactive and equivocal results flag as abnormal in Epic which indicates non-immune or equivocal immune status to rubella. A non-reactive result does NOT imply rubella infection. If ordered in workup of possible rubella infection, the IgG antibody results should be interpreted in conjunction with other laboratory tests, clinical history, and physical examination.
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.
Methodology:
Multiplex Flow Immunoassay
Sample
