Features and Advantages

By utilizing the slight differences between 13CO2 and 12CO2 in the absorption peak of infrared light, the HCBT-01 can detect whether the subjects have H. Pylori infection. The invention of the 13C-UBT System has dramatically improved the safety and convenience of UBT.

13C-UBT System is well-received among patients and medical institutions.

Principle of HCBT-01

CO2 has several characteristic absorption peaks in infrared band and there is a slight difference between the absorption peak positions of 13CO2 and 12CO2. By utilizing such slight difference, the HCBT-01 breath test analyzer is able to measure the concentrations of 13CO2 and 12CO2 respectively and then calculate the variation DOB (‰) of the abundance of 13C isotopes in the sample and baseline over the natural abundance of 13C, so as to determine whether the patient has been infected with H.Pylori.
