The heme occult test, also known as the fecal occult blood test (FOBT), is a medical screening test used to detect hidden blood in the stool. The presence of blood in the stool may be a sign of gastrointestinal bleeding, which could be caused by various conditions such as colorectal cancer, ulcers, polyps, or hemorrhoids. The heme occult test works by detecting minute amounts of blood that cannot be seen with the naked eye. The test typically involves collecting a small sample of stool and applying a special chemical reagent, such as guaiac or immunohistochemical, to the sample. If blood is present, a chemical reaction occurs and produces a color change. The presence of blood can then be confirmed by visual inspection or using a specialized device.
The presence of blood can then be confirmed by visual inspection or using a specialized device. Heme occult tests can be performed at home using commercially available test kits, or they can be done in a clinical setting. The test is non-invasive, relatively inexpensive, and easy to administer.
Fecal Occult Blood Test (FOBT)
You can have blood in your stool and not be able to see it. A fecal occult blood test is an at-home screening used to find the tiniest traces of blood in stool, which is a sign that something is wrong in your digestive tract. FOBT is often used for colorectal cancer screening, but a positive FOBT result on its own isn’t a cancer diagnosis.
It is recommended as a screening tool for individuals aged 50 and older to detect early signs of colorectal cancer. Additionally, the test may be used for patients with symptoms such as unexplained anemia, abdominal pain, or changes in bowel habits. A positive heme occult test does not necessarily mean that a person has colorectal cancer. Other conditions such as gastrointestinal bleeding from non-cancerous sources can also cause a positive result. Further diagnostic tests, such as colonoscopy or sigmoidoscopy, may be required to identify the cause of the bleeding. The heme occult test is an important tool in the early detection of colorectal cancer, as it can help identify individuals who may need further diagnostic evaluation. Regular screening can increase the chances of detecting colorectal cancer at an early stage when treatment is more effective and the prognosis is better. It is essential to follow up with a healthcare provider if a positive test result is obtained for appropriate diagnosis and management..
