The test result of H. pylori urease antibody 1.4ug/L should be judged in conjunction with a positive-negative test result, with a positive test result indicating a current or previous H. pylori infection and a negative test result indicating a normal test result. The normal reference value for H. pylori urease antibody is negative. A positive result indicates the presence of H. pylori infection, but does not indicate whether it is a previous or ongoing infection, and a C14 or C13 breath test is recommended to clarify the diagnosis. H. pylori is a micro aerobic bacterium parasitized in the mucosa of the human stomach, which can resist the acidic environment of the stomach and destroy the protective layer of the gastric mucosa, inducing gastritis, gastric ulcers and other gastric diseases. Since H. pylori is contagious, it is recommended that cohabitants also undergo further testing to clarify the presence of H. pylori infection. If the patient is diagnosed with H. pylori infection, it is recommended to go to the regular hospital in time, after clarifying the cause of the disease, under the guidance of the doctor to carry out targeted treatment to minimize the adverse effects of the disease.
