Reference Range:
<10.0 IU/mL Rubella IgG Quantitative Antibody Result Interpretation, Chemiluminescence Method:
<10.0 IU/mL
Negative: Non-immune, no significant level of detectable Rubella IgG antibody.
10.0-14.9 IU/mL
Equivocal: Repeat testing in 10-14 days may be helpful.

Positive: Immune, IgG antibody to Rubella detected, which may indicate a current or previous
exposure/immunization to Rubella.
IU/mL = International Units/mL

Seroconversion between acute and convalescent sera is considered strong evidence of current or recent infection. The best evidence for infection is a significant change on two appropriately timed specimens, where both tests are done in the same laboratory at the same time.
