Not a recommended test. False-positive results will occur due to low incidence of measles in the U.S.

|13.4 AU/mL or less||Negative - No significant level of IgG antibody to measles (rubeola) virus detected.|
|13.5-16.4 AU/mL||Equivocal - Repeat testing in 10-14 days may be helpful.|
|16.5 AU/mL or greater||Positive - IgG antibody to measles (rubeola) detected, which may indicate a current or past measles (rubeola) infection.|
The detection of antibodies to rubeola in CSF may indicate central nervous system infection. However, consideration must be given to possible contamination by blood or transfer of serum antibodies across the blood-brain barrier.
