FIELD: medicine and virology.
SUBSTANCE: invention relates to medicine and virology. The created test system for enzyme immunoassay of human blood serum, based on the use of a strain of metapneumovirus "NM-1", registered in HCV No. 2476 as a specific antigen accumulated in Hela cell culture and concentrated by differential centrifugation, is suitable for detecting IgM and IgG antibodies and determining their titer to metapneumovirus.
EFFECT: present invention enables to detect a significant increase in IgM and IgG titers and the level of non-immune individuals during serodiagnosis of metapneumovirus in patients. The invention can be successfully used by practitioners, laboratory assistants of medical institutions, especially in conditions of impossibility of PCR diagnostics and to confirm the infection with metapneumovirus.
