Additional Information

The Occult Blood Feces, Immunochemical method (Hemoccult ICT)may detect occult blood when it is the result of lower gastrointestinal tract bleeding, but may fail to detect upper gastrointestinal tract bleeding, producing a negative result. Therefore the Occult Blood, Feces Guaiac Method (Hemoccult Sensa) is used for suspected upper GI bleeding and Hemoccult ICT is used for suspected lower GI bleeding.
