Measles IgG


This test measures IgG antibodies to the measles virus which will tell you whether or not you are immune to measles. A result above a certain level will be reported as positive which means that you are immune to measles. Your result can also be reported as equivocal (which means that antibodies have been detected but they are not at a level where immunity is certain) or negative, which means that you are not immune to measles.

Measles is a contagious disease which is spread through coughing and sneezing. Measles causes symptoms such as a runny nose, cough and fever, red, light-sensitive eyes and small whitish spots on the inside of the cheeks. After a few days, a rash will develop. Measles often passes without incident, but in some cases serious complications such as pneumonia and encephalitis (swelling of the brain) can develop.

Immunity to measles is acquired through being vaccinated or as a result of having recovered from a previous infection. Once you are immune you are unlikely to catch measles again or pass measles onto another person. Health care workers may be required to prove immunity to measles by their employer.
