What is the EsoGuard® esophageal DNA test?
With ~90% sensitivity and ~99% negative predictive value at detecting Barrett's esophagus1,2,3 and esophageal adenocarcinoma,1,2 the EsoGuard test allows detection of these conditions in a simple office-based procedure without endoscopy.
The assay uses targeted next generation sequencing (NGS) to examine individual DNA molecules for the presence or absence of cytosine methylation at 31 different genomic locations.
How it Works
Cell Collection
Distal esophageal cells are sampled in a simple office-based procedure and sent to our laboratory.
Test
The EsoGuard Esophageal DNA Test assesses signature epigenetic changes indicative of BE and EAC using advanced molecular diagnostic techniques.
Results
The clinician receives a report with a positive or negative result indicating whether or not epigenetic changes consistent with BE/EAC were detected.
Who is at risk?
The risk of esophageal precancer is highest in patients with gastroesophageal reflux disease (GERD), age over 50, male, white race, obesity, smoking, and a family history of esophageal precancer (Barrett's esophagus) or cancer (esophageal adenocarcinoma).5,6
At least thirty million at-risk individuals with gastroesophageal disease (GERD), also known as chronic heartburn, are recommended for esophageal precancer testing by professional society clinical practice guidelines to prevent highly lethal esophageal cancer. Precancer detection is essential because esophageal cancer survival rates are poor, even when detected at Stage I.
