There are a number of methods a physician may use to evaluate your symptoms and determine whether or not they are caused by GERD.


Tests that may help your doctor make a diagnosis include an endoscopy with biopsy. You may need a referral from your primary care physician to see a gastroenterologist.

The gastroenterologist will examine your esophagus and take a tissue sample for testing. This procedure can help identify complications that may support a diagnosis of GERD or Barrett’s esophagus, a precancerous disease.

However, signs of GERD may not always be visible during the endoscopy. Therefore, your physician may recommend further diagnostic testing to assess your symptoms.


Additional diagnostic testing may be necessary to help your doctor better understand the root cause of your symptoms. Reflux testing measures pH levels in your esophagus to identify abnormal acid levels. A swallowing test evaluates the muscles in the esophagus to determine if your reflux is related to a motility disorder.


This advanced technology uses a small capsule to measure pH levels (acid content) in your esophagus for up to 96 hours.

  • Minimally invasive procedure
  • Allows you to continue regular daily activities and diet
  • Helps your physician make a confident diagnosis

This solution collects data through the length of your esophagus and identifies different types of reflux events.

  • Measures acid content in your esophagus
  • Monitors how long reflux events last
  • Helps your physician determine the root cause of your symptoms

This innovative system helps physicians better diagnose conditions related to esophageal motor function.

  • Procedure takes roughly 10 minutes
  • You will be asked to take deep breaths or swallow a number of times
  • The pressure resulting from these actions is detected and recorded for your doctor to review
