[The theory and practice of using in-house control in screening and verification studies for the diagnosis of HIV infection].
Three batches of two diagnostic test kits for the in-house control (IHC) HIV infection were made up of the 8 pools of sera, containing antibodies to all antigens of HIV-1 (4) and HIV-negative sera (4) obtained from healthy donors. All sera used for this purpose did not contain antibodies to viruses of hepatitis A, B, C. In the process of the preparation of the batches of diagnostic test kits for IHC 500 individual donor sera and more than 100 of individual sera of HIV-infected persons were studied. The sera under study were also tested for the presence (absence) of specific antibodies to HIV-1,2 and viruses of hepatitis A, B, C. The evaluation of IHC in 300,000 tests under the conditions of a screening laboratory and 550 verification tests was done. The study revealed that the use of IHC makes it possible to improve the conditions of work with commercial diagnostic test kits, to introduce the semiquantitative determination of the level of specific antibodies on verification tests and, on the whole, to standardize the tests.
