Positive cytomegalovirus IgG antibody means that the body has already produced antibodies against cytomegalovirus after a previous infection and has the ability to resist it, so it is safe to get pregnant and there is no need to worry too much. For those who are positive for cytomegalovirus IgM antibody, it means that they may have been infected with cytomegalovirus in the recent past, and if necessary, they will need to be retested or even need medication, which is not suitable for pregnancy for the time being. Screening for cytomegalovirus is one of the pre-pregnancy screening tests and is related to excessive close contact with pets. Therefore, there is no need to be overly concerned about IgG antibody positivity, but those with lgM antibody positivity need to be further screened.
