Cytomegalovirus IgM

About

Immunoglobulins or antibodies, play an important role in the immune system and help fight against harmful bacteria and viruses in the body. IgM antibodies are involved in the very early stages of an immune response and first to be made by the body when fighting a new infection, providing short-term protection.

What might a high result mean?

The presence of IgM antibodies indicates a recent CMV infection which could be due to a new infection, a reactivation or reinfection. The result of an IgM test alone cannot diagnose a CMV infection.
