Bernstein test

[bern´stīn] an acid perfusion test useful in differentiating esophageal pain from angina pectoris. The test requires passage of a nasogastric tube and instillation of an acid solution into the esophageal area. A lack of discomfort from the presence of the acid rules out esophagitis.

Bern·stein test

(bern'stēn), a test to establish that substernal pain is due to reflux esophagitis; performed by tubular instillation of a weak hydrochloric acid solution directly into the lower esophagus; symptoms disappear when the acid solution is replaced by normal saline. Synonym(s): acid perfusion 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.
