Anti-cytomegalovirus IgG positivity usually does not require specific treatment, but if combined with IgM positivity or nucleic acid testing, antiviral treatment for the cause is required.
Positive IgG on anti-cytomegalovirus antibody assay indicates a previous cytomegalovirus infection. IgG is an effector molecule involved in humoral immunity. When stimulated by cytomegalovirus, the body mounts an immune response and produces IgG upon re-stimulation, which usually does not require treatment.
This condition usually does not require treatment. An IgM test can be used to help diagnose the presence of a current infection. A negative IgM test indicates that there is no recent cytomegalovirus infection. A positive IgM test indicates that there is an active infection in the body, which may be the body’s first infection, i.e. a primary infection. It may be a primary infection, or a recurrent infection, in which the latent virus is activated when the body’s immunity is low, requiring antiviral treatment.
A cytomegalovirus nucleic acid test may also be performed, and if the result is positive, the diagnosis of cytomegalovirus infection is confirmed.
Ganciclovir needs to be used as prescribed by the doctor, and the treatment period is around 2-4 weeks, which needs to be decided according to the patient’s specific condition. Anti-cytomegalovirus IgG positivity is recommended to go to the hospital for a full examination to determine the status of the viral infection before treatment.
