Bernstein test

Alternative names:

acid perfusion test

How the test is performed:

The test is done in a laboratory. You are asked to swallow 2 or 3 very tiny tubes for the tests. In the Bernstein test, a hydrochloric acid solution (mixed especially for this test - an overdose of hydrochloric acid will not occur) and a saline solution are alternately injected into your esophagus. You need to say if there is any discomfort while the fluids are being run.

How to prepare for the test:

You must fast (no food or fluids) for 8 hours before the test.

Infants and children:
The physical and psychological preparation you can provide for this or any test or procedure depends on your child's age, interests, previous experience, and level of trust. For specific information regarding how you can prepare your child, see the following topics as they correspond to your child's age:

• infant test or procedure preparation (birth to 1 year)
• toddler test or procedure preparation (1 to 3 years)
• preschooler test or procedure preparation (3 to 6 years)
• schoolage test or procedure preparation (6 to 12 years)
• adolescent test or procedure preparation (12 to 18 years)

How the test will feel:

There is little discomfort with swallowing the tubes, but there may be a temporary gagging sensation. 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).
