Helicobacter pylori (Hp) worldwide human infection rate is more than 50%, can lead to a variety  of  digestive tract diseases, such as chronic  gastritis, atrophic gast ritis, peptic ulcer, gastrointestinal polyps, stomach cancer and so on.

Urea breath test (UBT) is the most widely used in clinic for the diagnosis of Helicobacter pylori. Because of its rapid, simple, non-invasive, high sensitivity and high specificity, it has become the most widely used and most accurate non-invasive test method for the diagnosis of infection in the world. Among all kinds of urea breath test technologies,¹³ C-UBT has a sensitivity and specificity of more than 95%, and is widely used because it is non-radioactive and has no special restrictions on subjects. ¹³C urea breath test tester in the domestic market also showed an increasing trend year by year. ¹³C-UBT test has been used in most physical examination centers and outpatient clinics.

The DOB-13C Urea Breath Detector Calibrator is used to calibrate the¹³C breath detector to ensure the accuracy and reliability of the measured value of the ¹³C breath detector, and to give the tested person accurate test results. DOB-13C Urea Breath Detector Calibrator, the type of source gas is DOB gas certified standard material, Urel≤1%, k=2; DOB measuring range is 0~50; Extended uncertainty Urel≤4%, k=2. The traceability of this Calibrator is calibrated by the Chinese Academy of Metrology.
