Results should be utilized in conjunction with other clinical and laboratory data to assist the clinician in making individual patient management decisions.

To avoid false negative results, no antibiotics, proton pump inhibitors, or a bismuth preparation should be administered to patient for 14 days prior to specimen collection.

Fecal specimens preserved in 10% formalin, Merthiolate formalin, sodium acetate formalin, or polyvinyl alcohol, or specimens that are in transport media such as Cary Blair or C&S cannot be used.

A negative test result does not preclude the possibility of the presence of H. pylori antigen in the specimen which may occur if the level of antigen is below the detection limit of the test.

This test has not been evaluated in a pediatric population.


When ordering tests for which Medicare or Medicaid reimbursement will be sought, physicians should only order tests that are medically necessary for the diagnosis or treatment of the patient. Components of the organ or disease panels may be ordered individually. The diagnostic information must substantiate all tests ordered and must be in the form of an ICD-10 code or its verbal equivalent.
