[Use of erythrocyte diagnostic agents in the universal system of serological reactions].

A method of parallel serologic studies of the material for the detection of specific antigen or antibodies is proposed. This method is not inferior to the known systems of serologic tests (passive hemagglutination-antigen neutralization tests, passive hemagglutination--antibody neutralization tests, etc) in sensitivity and economy, but exceeds all of them in informative value. The method has been tested both experimentally and in the epizootic study of plague infection used as a model. A serologic tests with the use of erythrocyte diagnosticums are based on a universal principle, this method may be used for other infections.
