What you can expect

By Mayo Clinic Staff

During a stool DNA test you collect a stool sample and submit it to your doctor's office or mail it to a designated laboratory.

You'll receive a stool DNA test kit for collecting and submitting the stool sample. The kit includes a container that attaches to the toilet and a preservative solution that is added to the stool sample before sealing the container. The stool DNA test requires only one stool sample.

After the stool sample is collected, it can be returned to the doctor's office or sent by mail to the laboratory.
