Hi my wife has recently been tested as positive for CMV (cytomegalovirus). She tested for CMV during her routine 20 week scan and the results was obtained today saying \"IgG positive - results 205\" and IgM non-reactive - results 0.09\".What can this tell us about change of primary infection vs non-primary infection?
Hi & Welcome. I appreciate your concern for your beloved wives result. Positive CMV Egg result indicates past or recent CMV infection. She may transmit CMV to the growing fetus through blood and tissue products. A non-reactive cytomegalovirus (CMV) IGM results suggest that the patient is not experiencing a recent infection. However, a negative result does not rule out primary CMV infection. The CMV IGM and Egg results should not be used alone to diagnose CMV infection. Results should be considered in conjunction with her clinical presentation & history and other laboratory findings.  In cases of suspected disease, the testing should be repeated in 10 to 14 days. Hope to have answered your query.
