Acid Reflux Tests & Diagnosis

Tests & Diagnosis

Several tests assist in diagnosing acid reflux. Detailed medical and health history records are important documents that can help illustrate the progression of a problem. Health records can help illustrate whether symptoms have become worse over time and whether more extensive tests are necessary.

Monitoring Tests

In order to diagnose gastroesophageal reflux disease (GERD), a pH monitoring test is necessary to monitor acid in the esophagus. This test can help assess whether acid reflux disease is present and what treatments are best able to help. It is possible to monitor pH in the esophagus and changes in pH levels for a period of up to twelve hours. Esophageal pH monitoring tests can be performed as an outpatient procedure.

X-Rays

A barium swallow x-ray is a test that is used to identify problems including stomach pain, weight loss, and blood in the vomit. Barium is a metallic element that an x-ray can detect. A person undergoing a barium test will swallow a liquid, and the x-ray will track this liquid as it passes through the digestive tract. A barium test will reveal damage to the esophagus, ulcers, and the presence of a hiatal hernia, a problem that occurs when the stomach moves above the diaphragm.

Endoscopy

Some people, especially patients who have already been diagnosed with GERD or acid reflux, will need to undergo a specialized endoscopy called an esophagogastroduodenoscopy (EGD). This test requires the use of a scope to visually inspect the mouth, throat, esophagus, and stomach. In general, the patient is asleep during this process. An EGD can help explain the extent of damage to the digestive tract.

A biopsy is required to detect certain kinds of inflammation, cell disorders, and pre-cancers. Barrett's esophagus, a tissue disorder that occurs when tissue that lines the intestine replaces the tissue that lines the esophagus, can be diagnosed using a biopsy.

An esophageal manometry is used to identify whether the sphincters are functioning properly. This test measures sphincter pressure to determine whether the connection between the esophagus and stomach is opening and closing properly.

Routine Tests

Routine tests are sometimes necessary for patients who have received a diagnosis. Regular tests can help explain whether a person has endured any temporary or permanent damage. Tests are necessary to assess what treatments are necessary and most effective. Only a doctor can determine when tests are necessary.
