acid infusion test

Bernstein test

A test for gastroesophegeal/gastro-oesophageal reflux disease (GERD/GORD), which is especially useful if endoscopic examination and distal oesophageal biopsy results are negative, and the diagnosis of GERD/GORDis suspected. The test determines whether a patient’s symptoms are related to reflux by reproducing them with acidification of the oesophageal mucosa. It is performed in a doctor’s office or lab and requires the patient to swallow 3 small-bore tubes into the stomach; a mixture of HCl and saline are alternatively injected into the tubes, and the patient then reports any symptoms experienced.
