Results

Interpretation

 < 13.5 AU/mL

Negative

Absence of detectable measles virus IgG antibodies.  A negative result generally indicates that the patient has not been infected and is susceptible to measles.  If the subject has no history of measles, has not been previously vaccinated and exposure to measles is suspected despite a negative finding, a second sample should be collected and tested no less than one to two weeks later.

≥ 13.5 AU/mL

and

< 16.5 AU/mL

Equivocal

Equivocal samples should be retested.  If the result remains equivocal after repeat testing, a second sample should be collected no less than one to two weeks later.

≥ 16.5 AU/mL
