What is the Faecal Occult Blood Test?

The Faecal Occult Blood Test (FOBT) is a non-invasive screening test used to detect hidden (occult) blood in the stool, which may be an early indicator of colorectal cancer or other gastrointestinal issues, such as ulcers, polyps, or inflammation.‍"Occult" means that the blood is not visible to the naked eye, so this test can detect small amounts that would otherwise go unnoticed.

What does it assess?

The FOBT measures the presence of microscopic blood in the stool. The test specifically identifies blood that could be coming from anywhere in the gastrointestinal tract, especially the colon or rectum.‍Detecting blood through this test can be a sign of colorectal cancer or other conditions, which can then be further investigated with additional diagnostic procedures, such as a colonoscopy, to determine the source of bleeding.

How do I optimize my Faecal Occult Blood Test results?

A diet rich in fruits, vegetables, and whole grains can support colon health and reduce the risk of colorectal issues.‍Fiber aids in digestion and may lower the risk of colorectal cancer.‍ Excessive consumption of red or processed meats has been associated with an increased risk of colorectal cancer.‍Reducing these foods and opting for leaner protein sources or plant-based proteins can benefit GI health. Adequate hydration supports digestive health and may reduce constipation and strain on the GI tract, which can benefit overall colon health.

What do good and bad Faecal Occult Blood Test results look like?

A positive FOBT result indicates the presence of blood in the stool, which may suggest gastrointestinal bleeding.‍This finding can be linked to a variety of conditions, such as colorectal cancer, polyps, ulcers, or inflammatory bowel disease.‍A negative FOBT result means no hidden blood was detected in the stool sample.
