Diagnostic Tests

Heartburn that occurs repeatedly should be evaluated by a doctor to determine what's causing the problem. There are specific diagnostic tests the doctor will use to determine if your heartburn is something more serious, such as gastroesophageal reflux disease (GERD).

Only a small percentage of patients will need the tests described below. The majority of doctors will prescribe a trial of acid-suppressive therapy, and make a diagnosis based on the patient's response to this.

If a doctor decides to order a diagnostic test, it may be one of the procedures below.

• Barium X-rays
• Upper Endoscopy
• PH Test
