Collection Instructions

Rotavirus is seasonal and is the most frequent cause of gastroenteritis in children inbetween 6 months and 3 years.

Collect specimens during the acute phase of gastroenteritis at which time viral particles and antigens are excreted in large numbers. Peak viral counts usually occur 3-5 days after the onset of symptoms. Samples collected more than 7 days after the onset of symptoms may not contain enough rotavirus antigen to produce a postive reaction.

Patient should pass the stool into a clean, dry pan or special container mounted on the toilet for this purpose. Transfer a "walnut" sized stool specimen into a clean leak proof container.

Do not collect specimens in containers having media, animal serum, detergents, or preservatives, as these substances may interfere with the assay.
