EnteroTrack LLC

EnteroTrack is a medical device company specializing in minimally invasive diagnostic equipment for eosinophilic esophagitis (EoE) management. The company manufactures and distributes the EnteroTracker®, a device used to perform the Esophageal String Test® (EST), a non-endoscopic, office-based procedure for collecting mucosal samples from the upper gastrointestinal tract. The EST enables clinicians to monitor esophageal inflammation in EoE patients, assess treatment response, evaluate food triggers, and reduce the need for repeated endoscopic procedures. The procedure involves a capsule attached to a string that patients swallow; the string remains in the upper GI tract for a physician-designated period and is then retrieved to collect fluid and mucus samples for analysis at reference laboratories. The test provides a liquid biopsy for disease-related biomarker analysis and eosinophil quantification, with published clinical data demonstrating 93.9% efficacy in distinguishing active EoE from treatment-associated remission. Medicare coverage for the EST became available, expanding patient access. EnteroTrack partners with academic medical centers including UC Denver Bioengineering, Children's Hospital Colorado, and University of Colorado Denver, and maintains relationships with advocacy organizations including APFED and CURED Foundation. The device is indicated for use in adult and pediatric patients. The company operates a growing network of test locations across the United States.
