Collection Requirements

Collect fresh stool in a plastic, leak-proof container. Adult and older children patients can collect the specimen by passing feces into plastic wrap stretched loosely over the toilet bowl. Then transfer 10 g of the stool specimen into the plastic container. With young children and infants wearing diapers, the diaper should be lined with clean plastic wrap to prevent absorption. A pediatric urine bag can be attached to the child to ensure that the stool specimen is not contaminated with urine. Then transfer 10 g of the stool specimen from the plastic lined diaper to the plastic container. Do not submit the diaper itself. Freeze and transport frozen.
