[Effective stabilizer for preparing antibody erythrocyte diagnostic agents for influenza A and B viruses]

A method for preparation of erythrocyte antibody diagnosticums capable of differentiating in PHA test the type and subtype appurtenance of influenza virus strains was developed on the basis of amidol sensitization of erythrocytes with immunoglobulin preparations and the use as a stabilizing agent of nonionic detergent triton X-100. The method is simple, highly sensitive, reproducible, and may be used at virological laboratories of practical health institutions.
