Overview

What is Urea Breath Test (H. pylori)?

Helicobacter pylori is a bacterium that lives in the stomach and is a common cause of gastritis, peptic ulcers and, over many years, a risk factor for stomach cancer. It is very common in India.

In the urea breath test you drink a solution containing labelled urea. If H. pylori is present, its enzyme (urease) breaks the urea down and the labelled carbon dioxide appears in your breath, which is measured in a breath sample. The test is accurate and is also used to confirm eradication after treatment.

Urea breath test for H. pylori: accuracy, preparation and next steps

Why test for H. pylori?

H. pylori infection is common and often causes no symptoms, but it can lead to gastritis, peptic ulcers and, over many years, increases the risk of stomach cancer. Testing is advised for people with ulcer disease, persistent indigestion, a family history of stomach cancer, and before long-term painkiller or aspirin use in some cases.

How accurate is the urea breath test?

The urea breath test is one of the most accurate non-invasive tests for active H. pylori infection, provided the preparation is followed. Blood antibody tests can stay positive after the infection has gone, so the breath test is preferred to check whether treatment has worked.

After a positive urea breath test

Treatment usually involves a combination of antibiotics and an acid-reducing medicine for 10-14 days. Taking every dose is important. A repeat urea breath test, at least four weeks after antibiotics and two weeks after stopping acid medicines, confirms whether the infection has cleared.

Urea breath test with Medigest

The test is advised after consultation with Dr. Shrihari Anikhindi at Medigest, West Punjabi Bagh, and the clinic arranges it. If you have alarm symptoms such as bleeding, weight loss or difficulty swallowing, an upper GI endoscopy may be advised instead.

Symptoms linked with H. pylori infection

Many people with H. pylori have no symptoms. Others notice upper abdominal burning or pain, bloating, early fullness, nausea or frequent burping. More serious problems include peptic ulcers, which can bleed, and, over many years, an increased risk of stomach cancer and a type of lymphoma. Testing and treating the infection reduces these risks.

Urea breath test versus other H. pylori tests

H. pylori can also be detected by a stool antigen test or by biopsy during endoscopy. Blood antibody tests are not recommended to check for current infection because they can remain positive for a long time after the bacteria have gone. The urea breath test is simple and accurate for both diagnosis and confirming cure.

Preventing reinfection

Reinfection after successful treatment is uncommon in adults. Clean drinking water, handwashing before meals and good food hygiene help reduce the risk for the whole family.

FAQ

Common questions about Urea Breath Test (H. pylori)

Why do I need to stop medicines before the test?

Acid-reducing medicines and antibiotics can suppress H. pylori and give a false negative result.

Is the urea breath test safe in pregnancy and for children?

The non-radioactive carbon-13 test is generally considered safe for children and in pregnancy. The doctor will advise which test is suitable for you.

What if my test is positive again after treatment?

If H. pylori persists, a different combination of antibiotics is used. Sometimes an endoscopy with biopsy culture is advised to choose the most effective treatment.
