An H. pylori test value of 500 dpm indicates an H. pylori infection that requires medication. Whether it is serious or not depends on the adverse effects of the infection and the results it causes. The normal value of gastric H. pylori is 0-110 dpm, and between 200-700 dpm, anti-H. pylori treatment can be considered. If it is greater than 700 dpm, consider giving a gastric triple (omeprazole, amoxicillin, metronidazole) or gastric quadruple (e.g., omeprazole, amoxicillin, metronidazole, bismuth potassium citrate, etc.) medication. If it is less than 200 dpm or less, clinical observation can usually be continued without specific treatment. If accompanied by clinical symptoms, such as stomach pain, epigastric discomfort, nausea, vomiting and other symptoms, it is recommended to wait for the symptoms to ease, and then promptly go to the hospital to improve gastroscopy, to see if there is erosion, ulceration and other conditions. Positive Helicobacter pylori, it is recommended to standardize the diagnosis and treatment under the guidance of a doctor, and the use of drugs in accordance with the doctor’s instructions.
