They should follow a logical sequence when more than one test is required for accurate diagnosis; that is, fecal occult blood tests to detect gastrointestinal bleeding; barium studies to visualize gastrointestinal structures and reveal any inflammation, ulcers, tumors, strictures, or other lesions; and endoscopic examinations to visualize an abnormality, locate a source of bleeding, and if necessary, provide biopsy tissue samples.
