| Abstract: | Study of different methods of hemosensitization helped detect the optimum technology for the preparation of parainfluenza (type 3) antigenic erythrocyte diagnosticum. This technology ensures the highest sensitivity, specificity, economy (with respect to viral antigen consumption) and stability of the reagent. Titration of antibodies by means of the new diagnosticum and the detection of parainfluenza cases among children with acute respiratory virus infections, acute and chronic glomerulonephritis have been highly effective, considerably more effective than similar determinations by the hemagglutination inhibition test. |
