Stool Collection - Pathogenic Organisms - Culture

Please collect stool specimens using the following guidelines. This will enhance recovery of pathogenic organisms and may eliminate the need for further or repeat testing.

Helpful Hints for Collection:

Standard Toilet: Use collection basin provided by the Lab. Avoid urinating in the basin.

Potty-Chair: Clean and thoroughly rinse reservoir. Allow to air dry before collection.

Diaper: Line diaper with plastic wrap or turn plastic-lined diaper inside out. Secure on child. Many disposable diapers have chemicals that will interfere with testing.

It is important that the stool specimen is NOT contaminated with urine or water. After bowel movement, transfer stool specimen to container provided by the laboratory.
