Herpesvirus 7 IgG and IgM Antibody Panel, IFA

Test Summary

Human Herpesvirus 7 (HHV-7), a close relative of HHV-6, is found in >85% of the population, with transmission occurring in early childhood. Like HHV-6, HHV-7 is a cause of exanthum subitum (roseola infantum). Due to the ubiquitous nature of HHV-7 infection, >80% of individuals in the general population exhibit HHV-7 IgG titers ≥1:20; however, only 5% of these individuals exhibit titers >1:320. Thus, HHV-7 IgG titers >1:320 are suggestive of recent HHV-7 infection. Detection of HHV-7 specific IgM is also indicative of recent infection.
