Helicobacter pylori Testing Seoul
English-friendly H. pylori evaluation in Gangnam for upper-abdominal pain, gastritis, indigestion, nausea, peptic-ulcer concerns, previous infection or confirmation after eradication treatment.
H. pylori is a stomach infection that can remain silent for years.
Helicobacter pylori is a bacterium that can live in the stomach lining and the first part of the small intestine. Many infected people have no noticeable symptoms.
In some patients, H. pylori contributes to chronic gastritis, peptic ulcers and other stomach complications. Testing is used to identify active infection so that appropriate eradication treatment can be planned.
At Apgujeong Hana Clinic, the testing method is selected according to symptoms, previous treatment, current medicines and whether gastroscopy is otherwise clinically appropriate.
H. pylori testing may be appropriate in several clinical situations.
Testing is selected after reviewing your symptoms, medical history, previous endoscopy results and medicines that may affect accuracy.
The best test depends on the clinical situation.
Breath and stool tests can detect active infection without endoscopy. Biopsy-based testing may be selected when gastroscopy is needed for symptoms or warning signs.
Urea Breath Test
During the test, the patient consumes specially labelled urea. H. pylori produces an enzyme that changes the urea, allowing related carbon dioxide to be measured in the breath.
Stool Antigen Test
This test checks a stool sample for H. pylori antigens. It may be used to diagnose active infection or confirm eradication after treatment.
Gastroscopy With Biopsy
Small tissue samples can be obtained during gastroscopy and examined for H. pylori, inflammation and other stomach-lining abnormalities.
H. pylori antibodies may remain positive after an old infection has been treated. A positive antibody result may therefore be unable to distinguish current infection from previous exposure and cannot reliably confirm eradication.
Certain medicines can temporarily reduce test accuracy.
Proton pump inhibitors, antibiotics and bismuth can reduce the amount of detectable H. pylori. Testing should be scheduled with appropriate medicine and timing instructions from the clinic.
Results should be interpreted together with preparation and symptoms.
Positive Result
A positive breath, stool or biopsy-based test generally indicates H. pylori infection. Treatment is selected according to previous antibiotic exposure, allergies, medical history and other clinical factors.
Negative Result
A negative result means H. pylori was not detected by that test. However, recent antibiotics, bismuth or acid suppression may reduce accuracy, so preparation and timing should be reviewed when suspicion remains high.
Upper-abdominal pain, nausea and fullness may also occur with reflux, functional dyspepsia, medication-related irritation, ulcers, gallbladder disease or other digestive conditions.
H. pylori treatment uses a complete combination regimen.
The exact regimen depends on antibiotic exposure, allergies, local resistance patterns, medication availability and previous treatment failure.
Feeling better does not confirm that H. pylori is gone.
Every treated infection should have eradication confirmed.
Breath or stool testing is commonly used after treatment. Biopsy-based confirmation may be used when repeat gastroscopy is needed for another reason.
Some symptoms may indicate an ulcer or digestive bleeding.
