One hundred and forty five stool samples from children below 2 years of age, hospitalized with diarrhea were tested for rotavirus antigen by enzyme linked immunosorbent assay (ELISA), latex agglutination test using commercially available kit Rotastat (Ranbaxy Diagnostic, India) and by polyacrylamide gel electrophoresis. Twenty eight samples were positive for the virus antigen by all the three assay systems. The sensitivity of latex agglutination (LA) and polyacrylamide gel electrophoresis (PAGE) was 91.4% (32/35) and 80% (28/35), respectively; the corresponding specificity was 98.18% (108/110) and 100% (110/110), respectively. Latex agglutination was the least complex, required the least amount of apparatus and provided a result within a short time. It showed a high specificity and a reasonable amount of sensitivity and the results correlated well with ELISA and PAGE.

D004797 Enzyme-Linked Immunosorbent Assay An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.
