Also Known As: FOBT, Stool Occult Blood Test, Occult blood test, Hemoccult test, Immunochemical FOBT, Guaiac Smear Test, and Stool Guaiac Test
Purpose of the Fecal Occult Blood Test
The fecal occult blood test is performed as part of a health and wellness screening or to confirm gastrointestinal bleeding as part of early detection for colorectal cancer, inflammatory bowel disease (IBD), and other related conditions.
What does the Fecal Occult Lab Test measure?
A fecal occult blood immunoassay detects blood in the stool that cannot be seen with the naked eye, known as occult blood. Using a fecal sample, blood is confirmed by determining the presence of a chemical reaction upon the introduction of specific substances, particularly guaiac and hydrogen peroxide.
Who Should Take a Screening Test for Fecal Occult?
Individuals at risk of colorectal cancer should take a fecal occult blood test as part of their annual screening or cancer work-up. These include people over 45 years old and those with a family history of cancer.
In addition, people planning to undergo weight loss should also consider adding the fecal occult lab test in their blood workup. Depending on the symptoms, physicians may also recommend the test to confirm other gastrointestinal disorders like Celiac disease, polyposis, and IBD.
Fecal Occult Blood Immunoassay Test Preparation
No special preparation, specifically drug or dietary restrictions, are generally required prior to the test. Results of this test are not affected by dietary peroxidases, animal blood, or vitamin C. If you have other questions or concerns, consult with your healthcare provider first.
