Which screening test is typically performed annually?

• A. GFOBT
• B. Cologuard
• C. Colonoscopy
• D. FIT

Answer: (A)

Screening frequency depends on the test type, and some tests are designed to be repeated yearly while others are done less often. The guaiac-based fecal occult blood test is traditionally performed every year as a simple, inexpensive way to screen for colorectal cancer by detecting hidden blood in stool. Because its sensitivity for early cancer is limited, repeating it annually helps catch cancers that might bleed intermittently. If the test is positive, the next step is a diagnostic colonoscopy to locate and remove any lesions. Cologuard, a stool DNA test, is not yearly—it’s generally repeated every few years. Colonoscopy is not annual either; it’s usually spaced about every 10 years for average-risk individuals because it directly visualizes the colon and can remove polyps in a single procedure. The fecal immunochemical test is another stool-based screen that is typically done annually, but in this context the classic association before newer options was with the guaiac-based test. So the annual screening choice best aligns with the traditional use of the guaiac-based fecal occult blood test.
