H. Pylori Test in Sharjah
Medically reviewed by Dar Al Kamal Team
What is an H. pylori test?
An H. pylori test looks for Helicobacter pylori, a spiral-shaped bacterium that survives in the acid of the stomach by burrowing into the protective mucus layer. The infection is usually picked up in childhood, often within families, and can stay for decades. It is a leading cause of stomach and duodenal ulcers and a long-term risk factor for stomach cancer, which is why doctors test for it and treat it when it is found.
Three tests are used outside an endoscopy, and each works in a different way:
| Test | Sample | What it detects | Best used for |
|---|---|---|---|
| Stool antigen test | A small stool sample | Proteins from the bacteria in the gut | Diagnosis and checking the infection has cleared |
| Urea breath test | Breath, before and after a drink | Carbon dioxide released when the bacteria break down urea | Diagnosis and checking the infection has cleared |
| Blood antibody test | A blood draw | Antibodies made by your immune system | A first check before any treatment |
The breath test relies on a clever feature of the bacterium. H. pylori makes an enzyme called urease, which splits urea into ammonia and carbon dioxide. You drink a solution of specially labelled urea, and if the bacteria are present, labelled carbon dioxide appears in your breath shortly afterwards.
At Dar Al Kamal Hospital, Sharjah, H. pylori tests are processed through the laboratory. When a gastroscopy is performed for other reasons, a small tissue sample taken during it can also be tested for the bacterium.
Who needs it
A doctor usually suggests H. pylori testing for:
- ongoing indigestion, upper abdominal discomfort, bloating or early fullness after meals
- a current or past stomach or duodenal ulcer
- a close family history of stomach cancer
- long-term use of anti-inflammatory painkillers or aspirin, where ulcer risk matters
- unexplained iron deficiency anaemia, in some cases
- confirmation that the infection has cleared after H. pylori treatment
Symptoms that overlap with acid reflux are common, and testing helps separate an infection that can be treated from reflux that needs a different plan. H. pylori is common in the UAE and across the region, so a doctor in Sharjah is likely to consider it early.
What happens
For a stool antigen test, you receive a clean container and a small scoop. You collect a sample at home, fill the container to the marked level, close it tightly and return it to the laboratory promptly, keeping it cool in the Sharjah heat on the way.
For a urea breath test, you arrive having fasted for the period you are given, usually from the night before. You breathe into a collection bag or tube to give a baseline sample, drink the urea solution, wait quietly, and then give a second breath sample. The whole visit is short and painless.
For a blood antibody test, blood is drawn from a vein in the arm in the usual way.
Stool and blood results are commonly ready within a day or two, and breath test timing depends on how the samples are analysed. Your doctor explains the result and, if the infection is present, plans treatment.
Preparing for it
Preparation matters most for the stool and breath tests, because some medicines suppress the bacteria and can hide an infection that is still there. Your doctor may ask you to pause:
- acid-reducing tablets of the proton pump inhibitor type, usually for a couple of weeks before the test
- antibiotics and bismuth-containing medicines, for a longer period beforehand
Simple antacids can usually be used for symptom relief in the meantime. Do not stop any prescribed medicine without checking with your doctor first, since some people need to keep taking them for safety reasons. The doctor gives you exact dates for your situation.
For the breath test, fast beforehand as instructed; a morning appointment is easiest. During Ramadan, a breath test fits naturally before Iftar, and your doctor can plan the timing with you. For a blood test, no fasting or medicine changes are needed.
Bring your Emirates ID, insurance card and request form. Walk-ins are accepted at Dar Al Kamal Hospital, Sharjah for most routine tests; for a breath test, confirm the fasting instructions first.
Afterwards
You can eat, drink and restart any paused medicines once the test is complete, unless your doctor tells you otherwise.
If the test is positive, your doctor prescribes a combination of medicines to clear the bacteria and explains how to take the full course. A follow-up stool or breath test some weeks after treatment confirms the infection has gone, with the same medicine pauses as before. Household members with symptoms may also be offered testing.
Go to the emergency department straight away if you vomit blood or material like coffee grounds, pass black, tarry stools, or have sudden severe abdominal pain. Contact the hospital if you have difficulty swallowing, weight loss you cannot explain or persistent vomiting.
Cost and insurance
Most UAE insurance plans cover H. pylori testing when a doctor requests it for symptoms, an ulcer or follow-up after treatment, and pre-approval is sometimes needed for the breath test. Some plans limit how soon a repeat test is covered. Dar Al Kamal Hospital, Sharjah can help you check your cover and any approval on 06 599 7777.

Frequently asked questions
What are the risks of an H. pylori test?
The risks of an H. pylori test are very small. A stool test carries no physical risk, the breath test involves only a harmless drink, and a blood test has the usual minor risks of a needle, such as a bruise. The main risk is a false negative if medicines were not paused beforehand.
Which H. pylori test is most accurate?
The stool antigen test and the urea breath test are both accurate for showing a current infection when medicines are paused correctly. The blood antibody test is less useful for this, because antibodies can remain after the infection has gone.
Can a blood test show whether H. pylori has been cured?
A blood test cannot show whether H. pylori has been cured, because antibodies often stay in the blood for a long time after successful treatment. A stool antigen test or breath test is used to confirm that the infection has cleared.
Why do I need to stop acid tablets before an H. pylori test?
Acid-reducing tablets and antibiotics can suppress the bacteria enough to make the stool or breath test look negative while the infection is still present. Pausing them for the period your doctor advises gives an accurate result.
Does a negative H. pylori test mean my symptoms are not serious?
A negative H. pylori test does not explain every stomach symptom. Reflux, ulcers from painkillers, gallbladder problems and other conditions cause similar symptoms, and warning signs such as weight loss or difficulty swallowing need further assessment, often a gastroscopy.
Is H. pylori contagious?
H. pylori can pass between people, most often within families and usually in childhood, through saliva or contaminated food and water. Good hand hygiene helps, and family members with symptoms can ask their doctor about testing.
Is the urea breath test safe in pregnancy and for children?
The urea breath test used for H. pylori is generally considered safe, and the stool antigen test is often preferred for young children because it is simple to collect. Your doctor chooses the most suitable test for pregnancy or childhood.
