FIT offers several advantages in the context of epidemiology: - Non-Invasive: Unlike colonoscopy, FIT does not require bowel preparation or sedation. - Cost-Effective: Given its low cost, FIT is accessible and can be widely utilized in population-based screening programs. - Convenient: The at-home collection process increases participation rates. - High Sensitivity and Specificity: FIT is more accurate in detecting lower gastrointestinal bleeding compared to older methods like guaiac-based FOBT.
