How to collect stool for testing

• Stool is another name for poop.
• It may be helpful to have a lab look at poop to know how to take care of a person.
• The lab calls what is collected for the test a stool specimen or sample.
• You are being asked to bring a stool sample from home for a test.

Important: Print your child’s name, birthday, and date and time stool was collected on the container or on the card.

If your baby or child wears a diaper or pull-up:

1. Line the diaper or pullup with plastic wrap, like Saran Wrap®. The plastic will be next to your baby or child’s skin. When your baby or child poops it will be on the plastic.
2. Use the stick and scoop the stool into the container or smear it on the card for the test your baby or child needs. The liquid part of the stool is needed for testing, so scoop that into the container or smear it on the card if you can.
3. Do not bring the diaper or pull-up to the lab. Only bring the stool sample in the container or on the card.

If your child uses a toilet:

1. Put the plastic “hat bowl” in the toilet. Your child can go to the bathroom into the hat.
2. Use the stick and scoop the stool into the container or smear it on the card for the test your child needs. Do not include urine, or pee, in the container.

When you are ready to bring the sample to the lab

• Allow extra time at the lab to register.
• Each stool sample must be put in its own container. Do not put more than 1 stool sample in the same container, unless the directions tell you to.
• The type of tests your child needs are circled. Get only one stool sample per day for all the tests except fat tests.
