Urea Breath Test (UBT) for H. Pylori
Enquiry Form
What is a Urea Breath Test?
The Urea Breath Test (UBT) is a quick, non-invasive test used to detect Helicobacter pylori (H. pylori) infection in the stomach. Unlike an endoscopy, it requires no scope, sedation, or needles — making it a comfortable first-line option for patients with symptoms of gastritis, acidity, or suspected ulcers.
What the UBT Is Used For
Detecting active H. pylori infection in patients with stomach discomfort, bloating, or acidity
Confirming whether H. pylori treatment has successfully cleared the infection
Screening as a preferred non-invasive alternative to endoscopy for initial H. pylori testing
How UBT Detects H. Pylori
H.pylori produces an enzyme called urease. When you swallow a small amount of urea-based solution, any H. pylori bacteria present break it down into carbon dioxide, which passes into your bloodstream and is exhaled in your breath. By comparing a breath sample taken before and after you drink the solution, the test can detect whether H. pylori is present.
Who May Need This Test
Anyone with persistent acidity, bloating, or stomach discomfort not explained by other causes
Patients being evaluated for gastritis or peptic ulcers
Patients who have completed H. pylori treatment and need confirmation it has cleared
Family members of someone recently diagnosed with H. pylori
How the Test Works
You’ll first provide a baseline breath sample. You’ll then drink a small amount of a urea-based solution. A second breath sample is collected roughly 15–30 minutes later, and the two samples are compared to determine whether H. pylori is present.
Preparing for Your UBT
- Avoid antibiotics and bismuth-containing medications for at least 2 weeks before the test
- Avoid proton pump inhibitors (PPIs) and other acid-reducing medication for the period advised by your doctor before the test
- You may be asked to fast for a few hours prior to testing
- Our team will confirm exact preparation instructions based on your current medications when your test is scheduled
What to Expect on the Day
The entire test typically takes under an hour and involves no discomfort — there’s no sedation, recovery time, or downtime, so you can resume your day immediately afterward.
Understanding Your UBT Results
A positive result means H. pylori bacteria were detected and treatment is likely to be recommended. A negative result means no active infection was found at the time of testing. Our specialists will walk you through your specific result and the next steps, whether that’s starting treatment or simply reassurance that H. pylori isn’t the cause of your symptoms.

UBT vs Other H. Pylori Tests
| Test | Invasiveness | Best Used For |
|---|---|---|
|
Urea Breath Test (UBT) |
Non-invasive (breath sample) |
First-line testing & confirming treatment success |
|
Stool Antigen Test |
Non-invasive (stool sample) |
Alternative first-line option, similar accuracy to UBT |
|
Blood/Serology Test |
Minimally invasive (blood draw) |
Screening only — cannot confirm active infection or cure |
|
Endoscopy with Biopsy |
Invasive (scope procedure) |
When symptoms are severe, or direct visual exam is also needed |
Why Choose Mira Healthcare
Mira Healthcare offers UBT testing alongside consultation and treatment planning in a single visit, so if H. pylori is detected, treatment can begin without delay. Our gastroenterology team determines when a UBT is sufficient versus when a more detailed evaluation, such as endoscopy, is warranted.

Frequently Asked Questions (FAQs) – Acid Reflux and Heartburn
No. It involves only breathing into a collection device and drinking a urea solution — there's no needle, scope, or sedation involved.
The Urea Breath Test is considered one of the most reliable non-invasive methods for detecting active H. pylori infection, and is widely recommended as a first-line test.
Yes. Antibiotics, bismuth-containing medicines, and acid-reducing medications (PPIs) typically need to be paused for a period before testing, as they can affect accuracy. Our team will confirm exact timing for you.
If you have alarm symptoms such as bleeding, unexplained weight loss, or persistent severe symptoms, or if a direct visual examination and biopsy of the stomach lining is needed, your doctor may recommend an endoscopy instead of or alongside a UBT.
Results are typically available quickly, and our specialists will explain what they mean and any recommended next steps during the same visit or shortly after.
You'll usually be asked to fast for a few hours before the test. Our team will give you exact instructions when your appointment is scheduled.
