[The serodiagnosis of viral hepatitis C and B in different population groups].

Data on the frequency of detection of serological markers of hepatitis C and B viruses using enzyme immunoassay for examinations of blood donors in different regions of the country, of patients with hepatitis of obscure etiology and patients with hemophilia regularly receiving hemostatic therapy are presented. The rate of detection of antibody to hepatitis C (anti-HCV) in reserve donors varied from 2% (Baltic states) to 9.2% (Moldavia), that of the carrier state of HBsAg from 0.3% to 10.3%, respectively. Among patients with hepatitis of obscure etiology, anti-HCV was found in 9-18%. A higher rate of anti-HCV was found in donors with high levels of aminotransferases (18.75%) and in patients with hemophilia (77.6%). Epidemiological serological surveys of group incidence of hepatitis revealed a high portion of incidence of virus hepatitis C (from 50 to 90%).
