Clinical laboratory equipment manufacturer

Clinical laboratory equipment manufacturerIt is an in vitro diagnostic instrument for detecting Helicobacter pylori in the human body, and is currently the "gold standard" for Helicobacter pylori testing, known as the "milestone in gastric disease testing".

A normal person does not have Hp in their stomach, and 13C labeled urea does not decompose. 13C urea is excreted through the urinary system. Urea reagents labeled with 13C are non radioactive and have no impact on the environment. Urea is a normal metabolic product in the human body, and this test has no side effects on the human body.

Clinical laboratory equipment manufacturerIt is a safe, convenient, sensitive, accurate quantitative, and non-invasive functional testing method that has been extensively explored and researched in clinical practice abroad, and is widely used in the diagnosis of digestive system diseases.

a) The subjects should be fasted in the morning or for at least two hours.

b) The subject maintained normal exhalation by blowing gas into the airbag until it was full, and immediately tightening the airbag cover. This collected breath was taken for 0 minutes.

c) After taking one bottle of urea 13C granules with 80-100ml of cold drinking water, the subjects sit still.

d) The subjects collected their exhaled breath 30 minutes after taking urea 13C using the above method, and then tightened the airbag cover.

e) The collected exhaled gas bags at 0 and 30 minutes are sent to the infrared analysis component. The infrared detector converts the optical signal into an electrical signal, which is amplified and sent to the microcontroller and computer for data processing. The 13C/12C ratio and its changes in the gas at 0 and 30 minutes are calculated to obtain the change in 13C content.

f) Display the analysis results and print them.

This instrument is used to qualitatively determine the presence of Hp in the human body by detecting the difference in exhaled breath before and after taking reagents in vitro based on the above principles.
