Principle

Helicobacter Pylori (HP) is a kind of gram-negative and non-spore bacillus in spiral bending which lives in gastric mucosa and duodenum. Helicobacter Pylori (HP) is the only bacterium which can generate lots of urease in stomach, so HP infection in stomach can be diagnosed through detection of urease. The urease decomposes urea into amine and carbon dioxide, the urea concentration will be reduced, conversely the amine concentration rise also pH value goes up, and accordingly the indicator of test card changes color (from yellow to cherry). For this reason HP infection can be denoted according to color change details.
