The physician orders a patient with a duodenal ulcer to take a UREA breath test. Which lab value will the test measure to determine if
H. Pylori is present?
Ammonia
Hydrochloric Acid
Potassium
Carbon Dioxide
The Correct Answer is D
Choice A rationale
The UREA breath test does not measure ammonia levels. While H. pylori can convert urea to ammonia and carbon dioxide, the test specifically measures the level of carbon dioxide in the breath.
Choice B rationale
The UREA breath test does not measure hydrochloric acid. Hydrochloric acid is produced by the stomach to aid in digestion, but it is not measured in the UREA breath test.
Choice C rationale
The UREA breath test does not measure potassium. Potassium is an important electrolyte in the body, but it is not related to the presence of H. pylori or the UREA breath test.
Choice D rationale
The UREA breath test measures carbon dioxide in the breath.
H. pylori bacteria break down urea into ammonia and carbon dioxide. Excess carbon dioxide in the breath is a sign of an H. pylori infection.
