Physician Office Specimen Requirements

Collect a minimum of 20 mL of very liquid stool. Send specimen refrigerated in a stool container.

Note:  1. Do not send formed stool. In the event a formed stool is submitted, the test will not be performed; and the report will indicate “A formed stool specimen was submitted for analysis. This test was not performed because it only has clinical value if performed on a watery stool specimen.”

2. Timed collections (24 hour) will also be accepted.

Note: Liquid stool is only acceptable specimen for this test.
