The stool guaiac test involves fasting from iron supplements, red meat (the blood it contains can turn the test positive), certain vegetables (which contain a chemical with peroxidase properties that can turn the test positive), and vitamin C and citrus fruits (which can turn the test falsely negative) for a period of time before the test.
The American College of Gastroenterology has recommended the abandoning of gFOBT testing as a colorectal cancer screening tool, in favor of the fecal immunochemical test (FIT). [3] The newer and recommended tests look for globin, DNA, or other blood factors including transferrin, while conventional stool guaiac tests look for heme.
Fecal occult blood testing (FOBT), as its name implies, aims to detect subtle blood loss in the gastrointestinal tract, anywhere from the mouth to the colon.Positive tests ("positive stool") may result from either upper gastrointestinal bleeding or lower gastrointestinal bleeding and warrant further investigation for peptic ulcers or a malignancy (such as colorectal cancer or gastric cancer).

A container of PEG (polyethylene glycol or macrogol) with electrolyte used to clean out the intestines before certain bowel exam procedures such as a colonoscopy. The colon must be free of solid matter for the test to be performed properly. [53] For one to three days, the patient is required to follow a low fiber or clear-liquid-only diet.
[1] [2] The test is performed by inserting a catheter, that contains a probe embedded with pressure sensors, through the anus and into the rectum. [3] Patients may be asked to perform certain maneuvers, such as coughing or attempting to defecate, to assess for pressure changes. [3] Anorectal manometry is a safe [4] and low risk [3] procedure.
