Scientists at ITMO University (fine mechanics and optics. – Ed. ) have developed a system for detecting Helicobacter pylori, bacteria that cause serious diseases of the gastrointestinal tract, such as ulcers, gastritis, and cancer. Its principle of operation is similar to common breath tests that analyze the composition of the air exhaled by a person, but the accuracy is much higher, the press service of the university told MV.
Used to identify the cause of stomach disease, the traditional urease breath test allows you to determine the presence of Helicobacter pylori infection in the body by exhaling a person. But the composition of the exhaled air and the ratio of carbon dioxide 12 and 13 in it can vary depending on gender, age, habits and eating habits, which leads to the need for repeated studies. The system proposed by ITMO scientists is more sensitive and detects the presence of Helicobacter pylori in the body with an accuracy of up to 98%.
