Fecal Occult Blood Tests (FOBT) are generally effective for screening colorectal cancer and detecting gastrointestinal bleeding, but their accuracy can vary. They may produce false positives due to dietary factors or certain medications, and false negatives can occur if bleeding is intermittent. For improved accuracy, it’s often recommended to use more sensitive tests, such as fecal immunochemical tests (FIT). Regular follow-up and confirmation with colonoscopy are advisable for positive results.

The Assay Test for fecal blood, commonly known as a fecal occult blood test (FOBT), is a diagnostic tool used to detect hidden (occult) blood in stool samples, which can indicate gastrointestinal issues such as polyps, ulcers, or cancers. The test typically involves a chemical reaction that identifies blood proteins, and it is often used as a screening method for colorectal cancer. Patients may be instructed to avoid certain foods and medications before the test to minimize false positives. Positive results usually warrant further investigation through procedures like colonoscopy.
What is a hemoquant blood test used for?
Hemoquant, another fecal occult blood test, is used to detect as much as 500 mg/g of blood in the stool. Like the Hemoccult, the Hemoquant test is affected by red meat. It is not affected by chemicals in vegetables.
