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.
What do you do if rubella IgM is positive?
