Bernstein test

Definition:

The Bernstein test attempts to reproduce symptoms of heartburn. It is usually done along with other tests dealing with esophageal functions.

Alternative Names:

Acid perfusion test

How the test is performed:

The test is done in a laboratory. A nasogastric (NG) tube will be inserted through your nostril and down into your esophagus. An infusion of mild hydrochloric acid is introduced through the tube, alternating with a saline solution, and you will be asked to report any discomfort you experience during the test.

How to prepare for the test:

You should not consume any food or fluid for 8 hours before the procedure.

Infants and children:

The preparation you can provide for this test depends on your child's age, previous experiences, and level of trust. For general information regarding how you can prepare your child, see the following topics:

Infant test/procedure preparation (birth to 1 year)
Toddler test/procedure preparation (1 to 3 years)
Preschooler test/procedure preparation (3 to 6 years)
Schoolage test/procedure preparation (6 to 12 years)
Adolescent test/procedure preparation (12 to 18 years)

How the test will feel:

You may experience some discomfort as the NG tube is placed. You may feel symptoms of heartburn while the hydrochloric acid solution is being administered.

You may have a mild sore throat after the test.

Why the test is performed:

The test attempts to reproduce symptoms of gastroesophageal reflux (stomach acids coming back up into the esophagus).
