Do I apply stool or water to the test card?

The FIT test uses the water from your toilet to test for hidden blood, not the stool itself. The test card might get a little colored, but that's okay.

If a clump of stool gets on the card, please discard the sample and reach out to support@poweredbyash.com to get a replacement kit. The lab cannot process the sample if it has too much stool on it.
