Safe for pregnant women and children over 3‚ it’s an accurate alternative to invasive procedures‚ offering a reliable diagnosis of stomach infections and ulcers.
What is H. Pylori?
Helicobacter pylori (H. pylori) is a bacterium that infects the stomach lining‚ causing conditions like gastritis and peptic ulcers. It produces urease‚ an enzyme breaking down urea into ammonia‚ neutralizing stomach acid and aiding survival. Infection often occurs in childhood‚ spreading through contaminated food or water. While many remain asymptomatic‚ chronic infection can lead to stomach ulcers or gastric cancer. Diagnosis is crucial for treatment‚ often involving non-invasive tests like the breath or stool antigen test. Eradication typically requires antibiotics‚ improving symptoms and reducing long-term risks. Understanding its role helps in managing gastrointestinal diseases effectively.
Purpose of the Breath Test
The primary purpose of the H. pylori breath test is to detect the presence of Helicobacter pylori bacteria in the stomach. It identifies the urease enzyme produced by H. pylori‚ which breaks down urea into carbon dioxide. This non-invasive method helps diagnose conditions like gastritis and ulcers without the need for endoscopy or biopsy. It is also used to confirm the eradication of the bacteria after treatment‚ ensuring the infection has been successfully cleared. The test is quick‚ painless‚ and highly accurate‚ making it a preferred diagnostic tool for both initial diagnosis and post-treatment follow-up. Its simplicity and effectiveness make it widely used in clinical settings.

Steps Involved in the Test
The H. pylori breath test begins with preparation‚ including fasting for at least one hour and avoiding certain medications like proton pump inhibitors. On test day‚ you drink a urea solution containing a small amount of radioactive material. After 10-15 minutes‚ you breathe into two foil bags to collect breath samples. The test measures carbon dioxide levels produced by H. pylori’s urease enzyme. Results are analyzed to determine infection presence. The entire process is non-invasive‚ pain-free‚ and typically takes 20-30 minutes. No endoscopy or biopsy is required‚ making it a convenient diagnostic option for patients.
How Breath Samples Are Collected
Breath samples are collected by having the patient exhale into specialized foil bags. Patients drink a urea solution containing a small amount of radioactive material. After 10-15 minutes‚ they breathe into the bags to capture carbon dioxide. The test measures levels of labeled carbon dioxide‚ which H. pylori produces by breaking down urea. The process is non-invasive and painless‚ requiring no needles or scopes. Patients must fast for at least one hour before the test and avoid certain medications. The collected samples are then analyzed in a lab to determine the presence of H. pylori. This method is safe for children over 3 and pregnant women‚ making it a convenient diagnostic tool.
