Questions about this test
Can I get the MMR vaccine if I am trying to conceive?
Yes, before pregnancy. Doctors usually advise waiting about a month after the vaccine before trying to conceive, and it is not given during pregnancy.
How soon after a rash does measles IgM turn positive?
IgM is usually detectable within a few days of the rash starting. If tested very early, the result may be negative and need repeating.
Why is measles reported to health authorities?
Measles spreads very easily, so confirmed cases help health teams protect contacts, especially babies and pregnant women.
