    Abstract:
    HHV-7 (Human Herpes virus type 7) is a relatively recently discovered, ubiquitous beta herpes virus. In Russia, the diagnosis of HHV-7 infection is carried out by PCR, which determines the DNA in serum or plasma, if there are clinical indications. Laboratory serological tests for HHV-7 are not performed. Currently, in the scientific literature, information on clinical studies of HHV-7 infection, its epidemiology, and its role in the etiopathogenesis of various diseases is insufficient. This article presents the results of the development of a test kit "ELISA-HHV-7-IgG", designed to detect specific IgG to HHV-7 by enzyme-linked immunosorbent assay (ELISA). Studies of the sensitivity and specificity of the developed test kit, including potential cross-reactive samples positive for other herpesvirus infections, were carried out. In the context of serological diagnostics, we studied samples of the sera of children (n = 167) and old people (n = 238) for the presence of IgG to HHV-7 with confirmation of the results in the indirect immunofluorescence reaction and the immune blotting reaction. The research results are evidence of the possibility of using the developed test kit for serological diagnosis of HHV-7 infection.
