Occult blood panel
Detects microscopic blood in stomach fluid.
Why This Biomarker Matters
Positive results indicate gastrointestinal bleeding, even when not visible. Helps identify serious conditions like ulcers or tumors requiring urgent endoscopic evaluation.
Overview
This test detects hidden (occult) blood in gastric fluid or stomach contents, invisible to the naked eye. It's used to identify gastrointestinal bleeding that isn't obvious, such as from ulcers, gastritis, or malignancy. A positive result warrants further investigation with endoscopy or imaging. The test is sometimes ordered in patients with unexplained anemia, abdominal pain, or when gastrointestinal bleeding is suspected but not visually apparent.
