HELIOBACTER PYLORI Accuracy of breath tests using low doses

Discussion: UBTs using 25 and 15 mg of 13C-urea were both accurate in the diagnosis of H pylori infection in untreated patients. 13C-UBT 15 mg was also accurate for follow up of patients after treatment. The urea breath test (UBT) for detecting Helicobacter pylori infection is a non-invasive method based on the organism s urease activity.

Point-of-care testing for Helicobacter pylori infection

There are a number of test types to diagnose HP infection available in clinical practice. They can be subdivided into invasive and non-invasive tests. Each test type requires a different sampling procedure, and has related benefits and drawbacks. The tests are summarised in Table 1. Point-of-care testing for Helicobacter pylori infection

What is a Helicobacter Pylori (H. pylori) breath test? The H. pylori breath test is a non-invasive, safe, painless and simple way to diagnose the presence of H. pylori, a bacterium that can be found in the stomach. The test is performed either To confirm whether you are suffering from H. pylori infection to help diagnose your condition.

It is important to note that these tests for H. pylori may be falsely negative in patients who have taken antibiotics, bismuth compounds or omeprazole in the past.

As no test is 100% accurate, there may be a case for using a concordance of two tests with different mechanisms, ie. urea breath test together with stool test or serology, in order to prove if the patient s H. pylori status is negative or positive. Particularly, positive serology tests need to be confirmed by other
