The occult blood fecal test checks for hidden blood in stool that you cannot see. It is ordered to screen for colorectal cancer or to investigate unexplained anemia or digestive symptoms.
What it measures
- Hemoglobin — A protein in red blood cells; its presence in stool suggests bleeding in the digestive tract.
- Heme — The iron-containing part of hemoglobin; detected by some stool tests.
- Human hemoglobin — Specifically identifies human blood, avoiding false positives from red meat.
- Fecal occult blood — General term for blood that is not visible to the eye.
Who it is for
This test is typically ordered by a primary care clinician or gastroenterologist for adults due for colorectal cancer screening or for patients with anemia or digestive symptoms.
Preparation

Results and what they mean
Results are reported as positive or negative for hidden blood. A positive result does not mean cancer; it means further testing is needed. Only a clinician can interpret your results. This is general information, not medical advice.
