Guaiac tests are the most widely used tests to detect colorectal cancer (CRC). However, their sensitivity is relatively low and results may be affected by various factors. Immunofecal occult blood test (IFOBT) is specific for human hemoglobin and does not require dietary restrictions. ⋯ Regular IFOBT can detect precancerous lesions and CRC in early stages and can thus reduce mortality from CRC.
