[Use of solid-phase radioimmunological analysis for the serological diagnosis of influenza].

Serum samples from 91 patients with acute respiratory infections were studied in different seasons of 1981-1983. The possibility of using the solid-phase radioimmunoassay for the serological diagnosis of influenza A was shown. The use of this technique made it possible to confirm the diagnosis of influenza A (H3N2) in 43.

[Immunoenzyme analysis. Quantitative determination of antibodies to the influenza virus].

Solid-phase immunoenzymatic procedure for quantitative estimation of antibodies to virus of influenza A was developed. A relationship was found between the rate of influenza virus adsorption on polystyrene and concentration of the cells, duration of the adsorption, temperature and the nature of buffer systems. Optimal conditions were developed for binding of the virus with polystyrene, immune sera and the conjugate IgG-peroxidase.
