Breath test for lactose, a test useful for exposing this intolerance, which affects a very important slice of the world’s population, almost 50% of the total. A non-invasive test that, however, requires a bit of time, about three hours. breath test has different meaning. mainly breath test refers a test in which police officers check how much alcohol a driver has drunk using a breathalyzer.

Lactose intolerance

The lactose is not more than a sugar present in milk which, to be digested and metabolized, must be broken down by a particular enzyme called lactose. Intestine is the inability to divide sugar “lactose” in two simple sugars: glucose and galactose are absorbed from the intestine. The body, therefore, can not metabolize and to assimilate in the correct way this substance. Lactose intolerance, which can be congenital, that is present from the first months of life, or acquired, is characterized by a series of symptoms typical annoying, such as bloating and abdominal pain, cramps, diarrhea, flatulence.


How do the breath test

Breath Test is used to detect the presence of the bacterium which causes serious disorders such as gastritis chronic type B. To verify the presence of lactose intolerance, the ally is the most effective diagnostic breath test, which occurs through the presence of hydrogen in the exhaled after ingesting lactose (20-50 g dissolved in water). The party does not have to do anything but blow on an empty stomach, preferably in the morning, in a special bag at regular intervals, which are usually about 20 minutes.

The reference values

By blowing into the bag, experts monitor the presence of hydrogen in the expired air after administration of the ad hoc lactose (the main suspect for intolerance and related symptoms). In particular, they are only indicative of some disturbance values: if there is an increase from baseline in the production of hydrogen of at least 20 ppm (parts per million) may occur, with reasonable certainty and reliability, the presence of intolerance to lactose.
