Is your heartburn a sign of a more serious condition?

Chronic heartburn can lead to esophageal precancer

EsoGuard is a DNA test that has been shown to accurately detect esophageal precancer.


Gastroesophageal reflux disease (GERD)

happens when digestive liquid from the stomach moves into the esophagus, causing irritation of the lining of the esophagus.


Symptoms of GERD

  • Heartburn

  • Regurgitation

  • Chest Pain

  • Nausea after eating

  • Sour tase in mouth

  • Coughing, choking or wheezing

  • Difficulty swallowing

  • Hiccups

  • Belching or burping excessively

  • Hoarseness or change in voice

  • Sore throat

  • Feeling that food is stuck behind the breastbone

  • Loss of enamel and tooth decay

Barrett’s Esophagus (BE) 

is a precancerous condition caused by damage to the lining of the esophagus from digestive liquids. People with GERD are more likely to have BE and it occurs more often in men than women and in people over age 50.

BE itself doesn’t cause symptoms, so many people are unaware that they have the disease and therefore unaware of their risk of developing cancer.


It is estimated that more than 18,000 people in the United States will be diagnosed with esophageal cancer and more than 16,000 people will die from the disease in 2020.


Early detection and diagnosis of BE and pre-cancerous cells is critical, allowing for surveillance and treatment before lethal esophageal cancer can develop.

Did you know that chronic heartburn can be a symptom of a more serious condition called Barrett’s Esophagus?

People with Barrett's Esophagus (BE) are at increased risk of developing esophageal adenocarcinoma (EAC) a deadly form of cancer.

Testing for precancer


EsoGuard is a DNA test that detects abnormal esophageal cells, such as Barrett's Esophagus, precancerous cells with dysplasia and cancer.

How it works

No blood or needles. 

Your doctor will perform a procedure to collect cells from your lower esophagus and ship them to our lab. 


Cell Collection

Your doctor will perform a cell collection procedure to gather cells from your lower esophagus for analysis. 




The collected cells are shipped to the our laboratory where the DNA is tested using the EsoGuard advanced molecular diagnostic test

Your healthcare provider will contact you with the results of your test, normally within 3 weeks.


If irregular cells are discovered your doctor will discuss appropriate treatment pathways. Finding BE early is key to reducing the risk of developing esophageal cancer.

Your DNA for early detection. 

Esophageal cancer is the 7th most common cause of cancer death among men in the United States. When it comes to cancer we know that early detection is key.
