Pregnant woman with positive cytomegalovirus IgM, when to do prenatal diagnosis

Patient's question:

On December 25th, a large cell IgM test result was positive with a value of 0.7. On January 15th, a follow-up IgM test result was 1.4. Currently, I am 3 months pregnant.

Doctor's answer:

The treatment of cytomegalovirus (CMV) infection can utilize various antiviral agents such as GCV (ganciclovir), CMV-specific immunoglobulin preparations, interferon, and transfer factor, among others. However, these medications do not address the root cause of the problem, and the virus often reappears after discontinuation of treatment. Given that this virus may be one of the causes of AIDS, scholars worldwide are dedicated to researching its infection control. Recently, American researchers have developed two live vaccines, which have shown promising results in initial trials. One is developed from the AD169 strain, while the other is produced from the Town strain. After non-oral administration, they have demonstrated significant efficacy against CMV, leading to an increase in CMV antibodies and enhanced immune function.
