Hemoccult testing is indicated when occult blood is suspected in stool due to:

• A. On all stool samples
• B. Dark and tarry stool suggesting occult blood
• C. For evaluation of diarrhea
• D. To monitor hydration

Answer: (B)

Fecal occult blood testing is used when there’s suspicion of hidden blood in the stool, indicating possible GI bleeding. When stool is dark and tarry (melena), it suggests that bleeding may be present somewhere in the upper GI tract and the blood has been digested; performing the Hemoccult test helps confirm whether occult blood is in the stool and guides further evaluation. This isn’t a routine test for every stool sample, nor is it the main tool for evaluating diarrhea or monitoring hydration. It’s specifically about detecting hidden blood in the stool when bleeding is a concern.
