Acid perfusion test

The Bernstein test is a method to reproduce symptoms of heartburn. It is usually done with other tests to measure esophageal function.

I Would Like to Learn About:

  • How the Test is Performed

    The test is done in a gastroenterology laboratory. A nasogastric (NG) tube is passed through one side of your nose and into your esophagus. Mild hydrochloric acid will be sent down the tube, followed by salt water (saline) solution. This process may be repeated several times.

    You will be asked to tell the health care team about any pain or discomfort you have during the test.

  • How to Prepare for the Test

    You should not eat or drink anything for 8 hours before the test.

  • How the Test will Feel

    You may have a gagging feeling and some discomfort when the tube is put into place. The acid may cause symptoms of heartburn. Your throat may be sore after the test.

  • Why the Test is Performed

    The test tries to reproduce symptoms of gastroesophageal reflux (stomach acids coming back up into the esophagus). It is done to see if you have the condition.

  • Normal Results

    The test results will be negative.

  • What Abnormal Results Mean

    A positive test shows that your symptoms are caused by esophageal reflux of acid from the stomach.

  • Risks

    There is a risk of gagging or vomiting.
