Negative CMV IgM results suggest that an individual is not experiencing a recent infection. However, a
negative result does not rule out primary CMV infection. It has been reported that CMV-specific IgM
antibody was not detectable in 10% to 30% of cord blood sera from infants demonstrating infection in the
first week of life. In addition, up to 23% of pregnant women with primary CMV infection did not
demonstrate detectable CMV IgM responses within 8 weeks postinfection. In cases of primary infection
where the time of seroconversion is not well defined, as high as 28% of pregnant women did not
demonstrate CMV IgM antibody. Positive CMV IgM results indicate a recent infection (primary,
reactivation, or reinfection). IgM antibody responses in secondary (reactivation) CMV infections have
been demonstrated in some CMV mononucleosis patients, in a few pregnant women, and in renal and
cardiac transplant patients with secondary rather than primary infections. Herpes Simplex Virus: Presence
of IgM class antibodies indicates recent infection.
