If only cytomegalovirus IgG antibodies are high, treatment is usually not necessary. If both cytomegalovirus IgG and IgM antibodies are elevated, cytomegalovirus infection is present, and medication is needed. 1. If the patient has increased cytomegalovirus IgG antibodies but not cytomegalovirus IgM antibodies, it means that the patient has been infected with cytomegalovirus, and usually no treatment is needed. 2. If the patient not only has increased cytomegalovirus IgG antibodies, but also has increased cytomegalovirus IgM antibodies, it is due to cytomegalovirus infection. 3. Patients need to be treated with antiviral drugs such as ganciclovir and valganciclovir under the guidance of a doctor. It is recommended that patients with high cytomegalovirus IgG antibody need to consult a doctor in time to check whether there is an increase in cytomegalovirus IgM antibody, and follow the doctor’s instructions to choose the appropriate measures for treatment.
