Helicobacter pylori Urea Breath Test
Also known as: Ubit, Urea Breath Test
Use
The urea breath test can be used to aid in the diagnosis of H pylori infection. The test can also be used to assess therapy when it is administered more than a month after completion of therapy.
Special Instructions
This test is applicable for adults and pediatric patients aged 3 to 17. Patients should fast for at least one hour prior to testing and must not consume antimicrobials, proton pump inhibitors, or bismuth preparations within two weeks prior to the test. The test solution contains phenylalanine, and phenylketonurics should be properly cautioned.
Limitations
The performance of the urea breath test may be affected by recent use of antimicrobials, proton pump inhibitors, or bismuth preparations. Patients on these medications should wait at least two weeks after discontinuation to undergo the test. Additionally, samples collected from individuals younger than 3 years old or those subjected to prolonged transport exceeding seven days will be rejected.
