Comment
Most laboratories now report only the qualitative result. There should be no digestion of urea in the absence of H. pylori infection.

Term Description

The patient ingests C-14 or C-13 (which is not radioactive) labeled urea , the clinic collects the patients exhaled breath and the lab measures the amount of the chosen isotope in the exhaled CO2. H pylori produces urease that digests urea to produce CO2. The most common isotope is C13 which is detected by infrared spectroscopy. Tagged CO2 in the breath is evidence of gastric Helicobacter pylori infection.

Part Description

LP15150-3   Carbon dioxide
CO2 content is a measurement of total CO2 in the blood. Most of it is in the form of bicarbonate (HCO3) controlled by the kidney. A small amount (5%) of CO2 is dissolved in the blood as insoluble carbonic acid (H2CO3). Changes in CO2 content generally relate to metabolic issues, renal function and unusual losses (diarrhea). Respiratory disease can ultimately effect CO2 content, but only slightly and only if prolonged.
