Fecal blood

More formally known as "hemoccult" or "guaiac", this is a quick test for bleeding from your gut. It could be anywhere from your throat to your anus. Even if you don't see anything that looks like blood when you move your bowels, this test is sensitive enough to detect it. Depending on your age, condition or family history, we may suggest periodic screening for colorectal cancer. It can also help in diagnosing ulcers, diverticulosis, hemorrhoids, etc.
