EoE Diagnosis

How is EoE diagnosed?

A referral to an eosinophilic oesophagitis (EoE) expert gastroenterologist is needed as the only way to make the diagnosis is by an endoscopic examination called a Gastroscopy where you will have 6 biopsies taken. 

The normal oesophagus has very few or no eosinophils in biopsy samples but patients with ​EoE have a clearly defined abnormality when the density of eosinophils are ≥15/hpf (equal to or greater than 15 per high ​power microscope field). 

Neither blood tests nor x-rays are of value in the ​diagnosis.

Learn about having a Gastroscopy in the video below

With thanks our medical advisor Dr Sarmed Sami, Consultant Gastroenterologist at University College London Hospitals NHS Trust (UCLH) and Digestive Health UK  for sponsoring and collaborating on this video.

Diagnosis delay

Many in our community find that obtaining a diagnosis is a long and often frustrating journey. Our charity’s mission is to change that and ensure that every person with EoE receives a prompt accurate diagnosis, the right treatment for them, and support to live with their condition.
