ColoCARE by Helena Laboratories is the leading throw-in-the-bowl fecal occult blood test for detecting pre-symptomatic bleeding caused by gastrointestinal diseases. Simply place a ColoCARE test pad in the toilet after a bowel movement, watch for a color change, then flush the pad away.
It's clean and disposable, easy for elderly patients to see and interpret, and extremely sensitive, with no increase in the false positive rate. It is more cost-effective than guaiac slide tests because it requires no stool handling, no chemical developers, no laboratory processing, and no mailing of biohazards. Elimination of stool handling overcomes the number one patient objection to occult blood testing, resulting in wider use of the test and leading to greater success in early detection of pathological conditions.
The test pad consists of biodegradable paper chemically treated with a chromogen. The pad is floated on the water surface in the toilet bowl. If detectable blood is present, the hemoglobin reacts with the chromogen, and a blue and/or green color reaction occurs. The test pad has three reaction sites: a large test square and two smaller control squares to verify the system functions properly.
