Heidelberg Testing

Appropriate production of stomach acid from the stomach lining is physiologically important for digestion, absorption, destruction of invading microbes, and inactivation of harmful foreign molecules. We perform a functional challenge test in the office of the stomach’s ability to produce acid with a sensor placed directly in the stomach while alkaline fluid challenges are swallowed and a transmitter monitors the patient’s ability to re-acidify the stomach contents. It is one of the gold standards for testing stomach acid.
