If the stomach problem caused by H. pylori is untreated, it can increase the risk of gastric disorders such as peptic ulcer disease, stomach cancer or gastric lymphoma.

HPTK is a medical kit to detect H. pylori infection. Based on the pH value of CO2 produced by H. pylori with carbon-13 urea reagent after dissolved in water, the users exhale into right/left HPTK breath collection bags, record the color changes of pH indicator before and after swallowing the reagent to compare with the universal color chart. If big difference occurs, further test is required. HPTK can prevent stomach disorders and reduce the consumption of medical resources.
