24.9 AU/mL or less: Negative - No significant level of detectable measles (rubeola) IgG antibody.
25.0-29.9 AU/mL: Equivocal - Repeat testing in 10-14 days may be helpful.
30.0 AU/mL or greater: Positive - IgG antibody to measles (rubeola) detected, which may indicate a current or past exposure/immunization to measles (rubeola).
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.
