Evaluation of a new enzyme immunoassay (TESTPACK rotavirus) for the detection of rotavirus in fecal specimens.

One hundred and forty fecal specimens were tested for rotavirus using two immunoassays, TESTPACK Rotavirus and Pathfinder Rotavirus. Five discordant specimens were evaluated by a blocking assay. The sensitivity, specificity, positive predictive value, and negative predictive value were 98, 100, 100, and 99% for TESTPACK and 92, 100, 100, and 96% for Pathfinder, respectively.
