Bacteria detected by breathing

Until now, doctors could only detect Helocobacter or ulcer bacteria: take a sample through the endoscopy of the gastric mucosa. But now it is enough to swallow a gentle lemon liquid and blow a tube in half an hour. Along with the liquid, the patient drinks several milligrams of water, in which the proportion of carbon 13 has varied properly to catch the bacteria Helicobacter. This bacterium consumes a lot of water and converts it to carbonic gas thanks to a specific enzyme.

Therefore, if there are no bacteria (or ulcers), there will be no dioxide enriched with carbon 13 in the patient's breath and vice versa. The cost of this system is three times lower than that of endoscopy. Gas analysis is performed using an isotopic mass spectroscopic procedure.
