DIAGNOSING GERD REFLUX TESTING AND TREATMENT

Testing by a gastroenterologist (GI) can determine whether your symptoms are caused by GERD.

HOW IS GERD DIAGNOSED?

An initial diagnosis of gastroesophageal reflux disease (GERD) may be made based on the frequency and severity of symptoms, along with a patient’s response to protein pump inhibitors (PPIs). However, neither symptoms nor a patient’s response to medication are enough to confirm a GERD diagnosis and identify an appropriate treatment. Objective testing by a gastroenterologist (GI) can determine whether your symptoms are caused by GERD.1,2

ENDOSCOPY WITH BIOPSY

An endoscopy with biopsy is one of the most common tests physicians use to confirm a diagnosis of GERD. To have the procedure, you may first 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.

However, signs of GERD may not always be visible during the endoscopy. Therefore, your physician may recommend further diagnostic testing to assess your symptoms.5


ADDITIONAL DIAGNOSTIC TESTING AND TOOLS

Additional diagnostic testing may be necessary to help your doctor better understand whether the root cause of your symptoms is related to motility (swallowing disorder) or reflux. Your physician may use any of the following Medtronic products to perform additional diagnostic tests.

Bravo Reflux Testing System

The Bravo™ reflux testing system’s advanced technology uses a small capsule to measure pH levels (acid content) in your esophagus for up to 96 hours.1 This test also allows your gastroenterologist to measure the effect of PPI medication on pH levels and reflux symptoms.

The Bravo reflux testing system:

  • Is a minimally invasive procedure
  • Allows you to continue regular daily activities and diet
  • Helps your physician make a confident diagnosis
  • Is preferred by 96% of patients over catheter-based tests4

DIGITRAPPER PH-Z TESTING SYSTEM

The Digitrapper™ reflux testing system collects data through the length of your esophagus and identifies different types of reflux events. Insights gained from reflux testing help your physician choose the right treatment option.

The Digitrapper reflux testing system:

  • Measures acid and non-acid content in your esophagus
  • Monitors how long reflux events last
  • Helps your physician determine the root cause of your symptoms5
  • Confirms effectiveness of PPI medication3

ManoScan High Resolution Manometry System

The ManoScan™ high resolution manometry system helps physicians better diagnose conditions related to dysphagia through a swallowing test.

During this diagnostic procedure, you will be asked to take deep breaths or swallow a number of times. The ManoScan high resolution manometry system detects and records the pressure resulting from these actions, which your doctor will review. The whole procedure takes roughly 10 minutes.
