Flushable reagent stool blood test is an at-home test to detect hidden blood in the stool.
This test is performed at home with disposable pads. You can buy the pads at the drug store without a prescription. Brand names include EZ-Detect, HomeChek Reveal, and ColoCARE.
You do not handle stool directly with this test. You simply note any changes you see on a card and then mail the results card to your health care provider.
To do the test:
The different tests have different methods to check for water quality. Check the package for instructions.
Some medicines may interfere with this test.
Check with your health care provider about changes in your medicines you may need to make. Never stop taking a medicine or change how you take it without first talking to your doctor.
Check test package to see if there are any foods you need to stop eating before doing the test.
This test involves only normal bowel functions, and there is no discomfort.
This test is mainly performed for colorectal cancer screening. It may also be done in the case of low levels of red blood cells (anemia).

The test can have false-positive (the test indicates a problem when there actually is none) or false-negative (the test indicates there is NOT a problem, but there is) results. This is similar to other stool smear tests which can also give false results.
