How is a patient with a positive fecal occult blood test (FOBT) evaluated?
- The evaluation of a positive FOBT depends somewhat on the clinical situation.
- Asymptomatic persons with positive FOBT and iron-deficient anemia require colonoscopy. If colonoscopy is negative for a source of FOBT or anemia, then esophagogastroduodenoscopy (EGD) should be performed.
