title: [Detecting the markers of HIV infection with the new enzyme immunoassay diagnostic kit "DS-EIA-HIV-AB-AG-SPECTRUM" at the laboratories of AIDS prevention and control centers in the Volga Federal District].
abstract: A possibility of simultaneously detecting specific antibodies to HIV-1 and HIV-2 by enzyme immunoassay (EIA) at lower concentrations than those by immunoblotting (IB), and well as an additional possibility of earlier diagnosis of HIV infection, by identifying the HIV-1 antigen p24 lay the foundation of the "DS-EIA-HIV-AB-AG-SPECTRUM" test system made by OOO "Research-and-Production Association "Diagnosticheskiye Sistemy" (Diagnostic Systems). These peculiarities were compared with those of IB at a number of laboratories of AIDS prevention and control centers in the Volga Federal District, by using native serum/plasma samples and a specially designed control panel. The analysis of the conducted studies to identify HIV-1 and HIV-2 antibodies and HIV-1 antigen p24 in 65 plasma/serum samples in the "DS-EIA-HIV-AB-AG-SPECTRUM" and "LIA-HIV-1/2" (OOO "Niarmedik plus") test systems while confirming the positive result indicated agreement in 57 (87.7%) cases. The diagnostic possibilities of the "DS-EIA-HIV-AB-AG-SPECTRUM" test system versus the "New Lav-Blot I" one to make a laboratory diagnosis of HIV infection were studied. Irrefragable answers as to the availability of HIV-1 markers in the study serum samples on the enciphered panel were provided by IB in 73.3% of cases and EIA in 92%.
