Fecal Occult Blood Testing (FOBT)
For Colorectal Cancer Screening
Guidelines from the American Cancer Society, the US Preventive Services Taskforce, and others recommend high-sensitivity fecal occult blood tests (FOBT) as on option for colorectal cancer screening.
- Colorectal cancer screening with FOBT has been shown to decrease both incidence and mortality in randomized controlled trials.
- High-sensitivity FOBT detects colorectal cancer at relatively high rates.
- Modeling studies suggest that the years of life saved through a high-quality FOBT screening program are essentially the same as with a high-quality colonoscopy-based screening program.
- Access to colonoscopy and other invasive tests may be limited or non-existent for many patients. In addition, some adults prefer less invasive test.
All of these elements make FOBT a reasonable choice for patients.
Recent advances in stool blood screening include the emergence of new tests and improved understanding of the impact of quality factors on testing outcomes.
