EsoGuard™ Esophageal DNA Test

EsoGuard™ is a Next-Generation Sequencing (NGS) assay optimized by ResearchDx scientists for the early detection of methylated DNA biomarkers associated with the presence of Barrett’s esophagus. In Barrett’s esophagus, the normal squamous cell lining changes to abnormal glandular cells as a result of chronic acid reflux. These cells have the potential to become cancerous unless they are detected and removed by endoscopy or radiofrequency ablation.

The EsoGuard test analyzes cells from the esophagus collected via a quick non-invasive office-based procedure using the EsoCheck device.
