[The diagnostic value of different test systems for the screening determination of antibodies to the human immunodeficiency virus].

Evaluation of the quality of enzyme immunoassay (EIA) systems by their sensitivity and specificity is inadequate, mainly due to the impossibility of detecting early or latent HIV infection in humans as it manifests by seroconversion only to a few HIV proteins. The additional evaluation criterion (confirmation rate) has been introduced, and an original method for the integral evaluation of the quality of assay systems intended for the diagnosis of HIV infection by EIA techniques has been proposed.
