Hello,
Thank you for your consult at DoctorSpring.com. I can understand your concern.

First and foremost, a positive Ig G indicates that your body has developed immunity against CMV.

Only a positive IgM test indicates an active / recent infection.

Merely a positive Ig G needs NO TREATMENT. It is of no concern at all.

Varying values of Ig G maybe observed at different readings, as there is no specific cut off.

I have gone through your reports, and I assure you that there is no cause for concern here, as your Ig M values are normal.
Have detailed ultrasound though, as that is an integral part of pregnancy screening, otherwise do not worry about these lab values.

All the best.
Hope this helps, Please feel free to ask for further clarifications.
