Bernstein test

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.

The Bernstein test was positive in 35 of the 58 patients.
Another 19 of these patients had a positive Bernstein test within 5 minutes of the onset of acid infusion, but 14 of them did not have symptoms during spontaneous reflux episodes of greater than 5 minutes.
The Bernstein test (dripping a mild acid through a tube placed in the mid-esophagus) is often performed as part of a complete evaluation.
