Diagnosing Eosinophilic Esophagitis (EoE)
How Do We Diagnose Eosinophilic Esophagitis?
The most reliable way to diagnose EoE is to examine a tissue sample (biopsy) under a microscope. However, if you are experiencing symptoms of GERD, we may also test for this condition as it can make a difference in how we treat you.
The Esophagus Center offers advanced tests, such as 24-hour esophageal studies and esophageal manometry. These tests help us learn more about your condition so we can determine the best treatment.
You may receive one or more tests including:
- 24-hour esophageal pH study: Using a tube with an acid (pH) sensor at the tip, or the Bravo® pH Monitoring Capsule, this test measures acid levels in your esophagus over a 24-hour period.
- Barium esophagram: This imaging study uses a special dye (barium) to show narrowing (stricture) and other abnormalities in your esophagus.
- Esophageal manometry: Passing a small tube through your nose to your esophagus, this test allows us to measure pressure and muscle contractions.
- Impedance test: This test measures how liquid moves from your stomach to your esophagus.
- Proton pump inhibitor (PPI) trial therapy: By temporarily going on special medication to reduce stomach acid, we can learn more about your condition. If you feel better after being on PPI, it’s likely you have EoE.
- Upper endoscopy: We pass an endoscope (a thin flexible tube) through your mouth and esophagus and carefully examine the lining of your esophagus. We may also take a tissue sample and examine it under a microscope.
