[A comparison of the efficacy of the passive hemagglutination reaction and the reverse passive hemagglutination reaction for detecting the rotavirus antigen in feces].

These two tests have been used for the detection of a rotaviral antigen in feces of patients suffering from gastrointestinal disorders. Antibody erythrocytic rotaviral diagnostic agent has been employed in both the tests. A comparative analysis has demonstrated the specificity of both the tests for the indication of a rotavirus and a higher sensitivity of passive hemagglutination.
