Additional information Foods with peroxidase activity (raw or undercooked meat, raw fruits and vegetables) may cause false positive reactions. Vitamin C or antacids may cause false negative results.

As with any occult blood test, the results of Gastroccult! test cannot be considered conclusive evidence of the presence of upper gastrointestinal bleeding or pathology.

Gastroccult! tests are designed as an aid to diagnosis, and are not intended to replace other diagnostic procedures such as X-ray studies or Endoscopy. Gastroccult! test results should only be used in conjunction with other information relevant to the clinical status of the patient. A positive test result may suggest the need for more careful monitoring of the patient.

Although a pH monitor is included on the gastroccult slide it cannot be used to determine the pH of the sample. This portion of the test is not Quality controlled nor validated at UCSF. If pH testing is required use pH paper according to the pH testing procedure.
