What happens if rubella IgG is detected in a blood test?
Q: My blood test report, Rubella IgG was detected. Please let me know about this. I am 23 weeks pregnant. What does this mean?
A:IF IgM for rubella is negative - no need to worry - this IgG positive indicates past infection or could be the result of the rubella (usually MMR) vaccine you had received in childhood.
