Welcome to EnteroTrack
EnteroTrack offers the Esophageal String Test® (EST). The only non-endoscopic, and office-based method to manage EoE
The EnteroTracker®
The EnteroTracker is used to perform the Esophageal String Test and aims to:
Provide a minimally invasive procedure that allows your doctor to collect samples from your esophagus.
Provide frequent monitoring of esophageal inflammation in Eosinophilic Esophagitis (EoE), reducing the need for repetitive invasive procedures.
Provide precise insights into disease progression, treatment responses, and management of (EoE).
Our easy four step process:

For EoE Patients
The Esophageal String Test is particularly valuable for patients with Eosinophilic Esophagitis who may need multiple procedures to:
- Monitor disease activity
- Assess response to treatment
- Evaluate for food triggers
- Reduce the need for repeated endoscopies
For Clinicians
The Esophageal String Test has demonstrated efficacy in monitoring Eosinophilic Esophagitis (EoE) and assessing the microbiome.
- Acquire mucosal content samples that serve as a liquid biopsy, facilitating analysis for disease-related biomarkers at reference laboratories.
- In-Office Monitoring of Eosinophilic Esophagitis
- The EnteroTracker® is a device to be used for collection of fluid/mucus from the upper gastrointestinal tract of adult and pediatric patients.

“It was a huge relief for him. It ended this yearslong dietary restriction.”

As a young kid, Jonah did something no kid wants to do: skip pizza and ice cream. When he was 5 years old, he told his parents there was a “ball in his throat,” a sensation linked to eosinophilic esophagitis (EoE).
