Measles and Mumps Tests – Positive, Negative

  • If the test result shows that IgM is positive, IgG is negative, then the possible interpretation is early infection;
  • If the result is opposite, then the possible interpretation is immunity from prior infection or vaccination;
  • If both IgM and IgG is negative, then the possible interpretation is no or low immune response due to compromised immune system.

A reference range is a set of values which helps the healthcare professional to interpret a medical test. It may vary with age, gender, and other factors.

Reference ranges may also vary between labs, in value & units depending on instruments used and method of establishment of reference ranges.
