For suspected measles cases, it is STRONGLY recommended to consult CADE regarding laboratory testing, which can consult on appropriate testing and facilitate specimen transport to SHL.

A Negative result indicates no significant level of detectable IgM antibody to Measles. A Positive result indicates a significant level of detectable IgM antibody to Measles and current or recent infection. An Equivocal result should be followed by a second sample in 14-21 days.
