1. The Hemoccult test is recommended for professional use as a diagnostic aid during routine physical examinations, for hospital patients to monitor for gastrointestinal bleeding in patients with iron deficiency anemia or recuperating from surgery, peptic ulcer, ulcerative colitis and other conditions, and in screening programs for colorectal cancer when the patient instructions are closely followed. Serial fecal specimen analysis is recommended when screening asymptomatic patients.
