There is a test that checks the urine for breath Bashny.Net

Find out how it is done and why nuzhen



Urea breath test - one of the most unpleasant examinations for admission to medical school. Not only is it disgusting in itself, as a bonus, there is also radiation emissions.

Chemists are not interested in euphemisms. When they found the main component of urine, then they gave him a name, and began to study it, to find out where he is taken. Then they went further: man forced to drink urine, to detect digested urine breathing.

In fairness it should be noted that the urea breath test did not come from the body of another person. In the body to assimilate proteins slowly decompose into amino acids, these amino acids and, in turn, they decompose in the liver by ammonia, carbon dioxide and water. Ammonia within the body should not be so to its natural formula, NH3, he receives a nitrogen atom, a hydrogen atom, carbon atom and oxygen atom.

The resulting compound known as urea or CH4N2O, is a white powder, a portable blood through the body without harm to the organism. The kidneys filter it, and then it is sent to the bladder and excreted from the body naturally.

However, just go to the toilet, to meet the need of chemists in urea, is not enough. In the form of resins and urea fertilizers are stored in large banks in biochemical laboratories, ready for any kind of experiments. It can be made in the laboratory by combining ammonia and carbon dioxide at high pressure, which is very convenient for doctors to add a bit of radioactive carbon-14 in the mixture. Then they are asked to swallow a man newly made urea and begin testing his breath: if the patient exhales carbon dioxide Tagged with carbon-14 in the next few minutes, doctors realize that urea is currently split into parts.

According to the laws of health for the fun of such a test can not be carried out - that must be a good reason. Fortunately, the doctors were able to justify their sense of humor to come up with well-founded excuse.



In 1982, researchers found that the bacteria Helicobacter Pylori cause chronic ulcer. Bacteria present in the digestive system, the majority of people in an excessive amount can become a cause great pain and indigestion. But these bacteria are partially comprised of the enzyme urease, urea splitting into two parts. Nothing else can break down urea so quickly after her swallow, so the presence of the labeled carbon dioxide in exhaled air allows doctors to find out whether in the stomach in pain a person overabundance of bacteria.
