title: Laboratory diagnosis of rotavirus infection in diarrhoeal patients by immunoenzymatic and latex-agglutination assays.
abstract: One hundred stool samples from children with acute diarrhoea were examined by six commercial latex and immunoenzymatic assays for the diagnosis of rotavirus infection in four different laboratories. Samples were also analyzed by solid-phase immune electron microscopy using a rabbit anti-group A rotavirus antiserum. With electron microscopy as a basis for comparison, sensitivity and specificity for the latex and ELISA assays varied from 91.1 to 92.9% and from 94.2 to 99.4%, respectively. Statistically significant differences were revealed in the confirmation rate of electron microscopy-negative samples between different commercial assays. Significant variability was also found between results obtained by the laboratories taking part in the study.
