Reference Interval:
0.89 IV or less: Negative - No significant level of IgG antibody to measles (rubeola) virus detected. 0.90-1.09 IV: Equivocal - Repeat testing in 10-14 days may be helpful. 1.10 IV or greater: Positive - IgG antibody to measles (rubeola) detected. Suggestive of current or past infection.
