How to prepare

- Collection. Collect stool from a clean surface or a diaper, not from the toilet water. Do not mix in urine.
- Delivery. Bring the container to the lab the same day. Ask the lab how to store it until then.

Common questions
Can I collect stool from a diaper?
Yes, if it has not soaked in. Scoop it from the surface of the diaper with the spoon.
Are antibiotics needed for rotavirus?
Usually not. It is a virus. Drinking fluids is the main thing. Your doctor will prescribe treatment.
