A member asked:

I did a rubella virus test and my igg 17 iu/ml, and igm 0.120. i would like to know that i have rubella virus and what does the "retesting zone" mean?

A doctor has provided 1 answer

Rubella virus: Virus exposures can elevate IgM antibodies (showing recent exposure to the rubella virus) or with previous exposure, provide IgG antibody positives. The critical element with rubella is whether exposure occurred during an early pregnancy. "Re-testing" is done to see if the IgM antibodies are rising, indicating if pregnant whether the chance for fetal infection is present.
