Laboratory Studies

Rotavirus may be identified by several means (ie, enzyme immunoassay being the most common, latex agglutination, electron microscopy, culture). [1] However, in most cases, identification of the virus is important for public health or infection control purposes. [1] In general, use of such testing is less useful in the ED and can take significant time (days to weeks) for results to return.

Electrolyte levels should be measured with severe dehydration, alterations in mental status, associated seizures, or oral replenishment with excessive water or salt.
