A positive H. pylori 330 dpm suggests that the organism is infected with H. pylori. Normal values for H. pylori are tested differently. The normal value of carbon 13 breath test is less than 4 dpm; the normal value of carbon 14 breath test is less than 100 dpm. 330 dpm, regardless of the above test methods, is positive, indicating that the body is infected with H. pylori in large quantities. H. pylori infection may cause chronic gastritis, gastric ulcer, etc., and if not treated in time, it may also induce gastric cancer and other diseases. H. pylori infection is usually eradicated by triple or quadruple therapy, and it is recommended to go to the gastroenterology department of a regular hospital and follow the doctor’s instructions for treatment.
