Cytomegalovirus (CMV) is a virus from the herpesvirus family that can cause a variety of clinical manifestations, from ARVI to internal organ and nervous system damage. It is considered to be an opportunistic infection that can be dangerous for immunocompromised patients (e.g., those with HIV infection or during pregnancy).

IgM antibodies to CMV appear 1-2 weeks after infection and can remain in the body for up to 10 months during primary infection. During reactivation of the infection, the antibody titer may vary depending on the activity of the virus and the state of the immune system.

The IgM titer is an important indicator of the activity of the infectious process, and its determination allows to assess the presence of primary infection or reactivation of latent infection.
