This is a test performed at home with disposable pads. The test detects the presence of hidden (occult) blood in the stool. The pads are available at drugstores without a prescription.

Brand names include EZ-Detect™ and ColoCARE.

There is no direct handling of stool with this test. You simply note any changes on a card and then mail the results card to your physician.

Urinate if you need to, then flush the toilet before you defecate. After the bowel movement, place the chemically treated tissue pad in the toilet. Watch for a change of color on the test area of the pad (results usually appear within two minutes). Note the results on the card provided, then flush the pad away. Repeat for the next two consecutive bowel movements.

The different tests have different methods to check for water quality. Check the package for instructions.

Some drugs may interfere with this test.

Check with your health care provider regarding medication changes that may be necessary. Never discontinue or decrease any medication without consulting your health care provider.

Check package instructions for food restrictions.

This test involves only normal bowel functions, and there is no discomfort.
