Which test is used to detect hidden blood in stool as described?

• A. Complete blood count
• B. Urine analysis
• C. Occult blood test
• D. Liver function panel

Answer: (C)

Detecting hidden blood in stool is about screening for gastrointestinal bleeding and colorectal issues, and the test designed for this is the occult blood test. It analyzes stool samples to find trace blood that isn’t visible, using methods like the guaiac-based test or immunochemical tests (FIT). A positive result can prompt further investigation for potential bleeding sources, including polyps or cancer, while a negative result makes significant hidden bleeding less likely. Other tests mentioned don’t target stool blood: a complete blood count looks at blood cells and anemia, urine analysis checks urine components, and a liver function panel assesses liver health. The occult blood test is the one that directly detects hidden blood in stool.
