Helicobacter pylori (H. pylori) is a common bacterial infection in the stomach lining that affects more than half the world’s population and plays, if left untreated, a key role in the development of peptic ulcers, chronic gastritis, and gastric cancer.  

At United Digestive, we offer the H. pylori breath test, a simple, noninvasive way to detect an active Helicobacter pylori (H. pylori) infection. This bacterium can cause stomach ulcers, gastritis, and other digestive conditions. During the test, you provide breath samples before and after drinking a special solution. If H. pylori is present, it breaks down the solution and produces carbon dioxide, which can be detected in your breath. This accurate, noninvasive test helps diagnose active infection so you can receive effective treatment and long-term symptom relief.

Patients can review important patient instructions prior to their appointment to help ensure accurate testing results: English / Spanish / Vietnamese / Korean

FAQs

Yes. It can spread through saliva, contaminated food or water, or close contact with an infected person. That’s why accurate diagnosis and treatment are important.

You may benefit from H. pylori testing if you experience: 

  • Recurring or persistent abdominal pain 
  • Frequent bloating, nausea, or vomiting 
  • Loss of appetite or unintended weight loss 
  • Black, tarry stools or symptoms of anemia 
  • A history of ulcers or gastritis 
  • Family history of stomach cancer 

 

Testing is also recommended prior to starting long-term NSAID therapy (e.g., ibuprofen) in certain patients, or if you’ve previously been treated for H. pylori and need to confirm eradication. 

The urea breath test (UBT) involves the patient drinking a special liquid and providing a breath sample, which will show elevated carbon dioxide levels if H. pylori is present. 

 

The test is: 

  • Simple and outpatient 
  • 94–100% accurate 
  • Covered by most insurance plans 
  • Used both for diagnosis and confirmation of successful treatment
