What is Fecal Occult Blood?
Fecal occult blood refers to minute quantities of blood present in stool that are invisible to the naked eye. Although undetectable without specific testing, its presence can indicate a variety of gastrointestinal conditions.
- Diseases Associated with Fecal Occult Blood
Fecal occult blood can signify a range of gastrointestinal issues:- Gastric and Duodenal Ulcers: Bleeding may occur from lesions in the stomach or duodenum.
- Colorectal Polyps: These abnormal growths in the colon or rectum often bleed.
- Colorectal Cancer: This life-threatening disease progresses silently in its early stages. According to the World Health Organization (WHO), colorectal cancer is the third most common cancer globally, with 1.9 million new cases and nearly 935,000 deaths in 2020. Early detection dramatically improves outcomes, with a five-year survival rate of up to 90% when identified early compared to only 14% in those advanced, metastatic cases.
Methods for Detecting Occult Blood in Stool
There are two principal detection methods:- Chemical Method: Uses the peroxidase-like activity of hemoglobin but is prone to false positives due to dietary factors (e.g., red meat) and certain medications.
- Immunological Method (FIT): Employs antibodies to detect human hemoglobin with high specificity, reducing false positives caused by external interferences. This method is the preferred choice globally for its accuracy and reliability.
Benefits of Fecal Occult Blood Testing
- Early Disease Warning: Enables the identification of digestive diseases before symptoms arise.
- Treatment Monitoring: Assesses the efficacy of therapy and detects recurrence of bleeding in patients with gastrointestinal disorders.
- Colorectal Cancer Screening: Plays a pivotal role in improving treatment success rates and long-term survival through early diagnosis.
Guidelines on Fecal Occult Blood Testing
Global health organizations emphasize the importance of fecal occult blood testing as part of colorectal cancer screening programs:1. WHO Recommendations: Regular FOBT is advised for average-risk individuals aged 50–74, with immunological methods (FIT) as the preferred choice due to their high sensitivity and specificity.
2. United States Preventive Services Task Force (USPSTF): Suggests annual FIT screening starting at age 45-49.
3. European Guidelines: Recommend biennial FIT-based screening for individuals aged 50–74.
