Flushable reagent stool blood test
Alternative namesThis is a test performed at home with disposable pads that 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.
How the test is performed
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). Repeat for two more consecutive bowel movements. Note the results on the card provided. Then flush the pad away.
The different tests have different methods to check for water quality. Check the package for instructions.
