- 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.
