CMV antibody tests
People who have never been infected with CMV have no detectable antibodies to CMV.
Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.
The presence of antibodies to CMV indicates a current or past infection with CMV. If the number of antibodies rises over a few weeks, it may mean that you have an acute infection.
Chronic CMV infection (in which the antibody count stays about the same over time) can reactivate in a person with a suppressed immune system.
