C14 Helicobacter Pylori Detector

The [14C]-Urea Breath Test (UBT) is based on the detection of the enzyme urease, produced by Helicobacter pylori. Since urease is not present in normal human tissues, and since other urease-producing bacteria do not colonize the stomach, the presence of urease in the stomach can be equated with Helicobacter pylori infection.

In the presence of urease, orally administered 14C urea will be hydrolyzed into ammonia and 14CO2. 14CO2 is absorbed into the blood circulation and exhaled by the lung. The presence of a significant amount of 14CO2 in the exhaled breath indicates active Helicobacter pylori infection.

Perform the test in 3 easy steps:

1. Swallow a 14C-Urea capsule with water and Wait for 15 minutes.

2. Blow into a breath card for 3-5 minutes

3. place the breath card in detector for analysis


The design of Helicobacter Pylori Detector HUBT-20A is aimed to provide a simple and easy-operated method to detect Helicobacter pylori infection. Improved from HUBT-20, the new generation HUBT-20A provides more advanced features. The renovation in appearance creates a more exquisite outline. It provides dual-channel option which allows simultaneous independent measurement to help improve test efficiency. Professional software enables the operators to manage patient’s database. PC connection realizes information resource sharing.

Helicobacter Pylori Detector HUBT-20 uses high sensitive thin-film GM Tubes to detect theβ-ray energy of 14C. The β-ray in GM tube makes inert gas ionized. The anions of gas ionized are speeded up to move to the anode of the GM tube under a strong electric field, and more gas is ionized by collision with other gas molecules. Lots of charged ions are generated instantly under these conditions. A detectable negative pulse is generated, and then is input into the single chip microcomputer system and is counted after it is amplified, handled and discriminated. The final data processing value is shown on the LCD and printed through the printer.
