Carbon dioxide post dose urea:ACnc:Pt:Exhl gas:Qn:LOINC code
Preferred Label : Carbon dioxide post dose urea:ACnc:Pt:Exhl gas:Qn:;
LOINC status : DISCOURAGED;
LOINC display name : CO2 post dose urea Qn (Exhl gas);
LOINC long common name : Helicobacter pylori [Quantitative] in Stomach by urea breath test;
LOINC short name : Urea Breath Test-aCnc;
LOINC 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.;
