Introduction
Under normal circumstances, "CMV IgG" refers to cytomegalovirus (CMV) IgG antibody. A positive CMV IgG antibody result indicates that the patient has previously been infected with cytomegalovirus. CMV IgG antibodies are immunoglobulin G antibodies produced by the body following CMV infection. IgG antibodies are a type of immunoglobulin that can persist in the body for a long period of time.
In general, "CMV IgG" refers to cytomegalovirus (CMV) IgG antibody. A positive CMV IgG antibody result indicates that the patient has previously been infected with cytomegalovirus. The detailed explanation is as follows:
CMV IgG antibodies are immunoglobulin G (IgG) antibodies produced by the body following cytomegalovirus infection. IgG antibodies are a type of immunoglobulin that can persist in the body for a long time. This indicator helps determine whether a patient has had prior exposure to CMV. Therefore, a positive CMV IgG antibody test usually suggests previous CMV infection. It should be noted that since CMV IgG antibodies can remain in the body for an extended period, a single positive IgG result alone is not sufficient for definitive diagnosis. The result should be interpreted together with the CMV IgM antibody test for accurate assessment.
If CMV IgG antibodies are positive, it is important to seek medical attention promptly. Under the guidance of a physician, the underlying cause should be investigated and appropriate treatment initiated to avoid delays in managing the condition.
