Clinical laboratory equipment Helicobacter pylori detector carbon-14

Clinical laboratory equipment Helicobacter pylori detector carbon-14It is a Gram negative Helicobacter pylori that parasitizes the human gastric mucosa. In 1983, Marshall et al. cultured Helicobacter pylori (Hp) from human gastric mucosal tissue and believed that this bacterium is a pathogenic bacterium that causes chronic gastritis and peptic ulcers. It can survive in high levels of stomach acid, not only wrapping around the gastric mucosa, but even crossing the protective barrier of the stomach, causing lesions in the stomach.

Helicobacter pylori (Hp) is the main culprit of peptic ulcers (gastric ulcers, duodenal ulcers) and chronic active gastritis, and it has been listed as a Group I carcinogen by the World Health Organization (WHO).

Clinical laboratory equipment Helicobacter pylori detector carbon-14It is an instrument used by medical institutions to detect Helicobacter pylori infection in the human stomach. After oral administration of urea [14C] capsules, if Helicobacter pylori (Hp) is present in the stomach of the subject, the urease produced by Hp will decompose urea into 14CO2. By using the LZS-HP-200 series Helicobacter pylori detector to detect the amount of [14C] in exhaled gas, it is possible to diagnose whether the patient is infected with Helicobacter pylori.
