Two (+) signs for H. pylori represent a more serious condition. Generally, testing for H. pylori can be of two natures, one being a qualitative test, which is either negative or positive. Positive will be divided into one (+) to three (+) ranging. The other is quantitative, like the carbon 13 breath test, or the carbon 14 breath test, with a reference value at less than 4. If the test is greater than or equal to 4, the diagnosis of H. pylori infection is made. If the patient tests for two (+) H. pylori, the patient is considered to be more serious. This is because H. pylori infection can cause a range of upper gastrointestinal diseases, such as chronic gastritis, peptic ulcer, gastric cancer or gastric lymphoma, among others. Therefore, if the patient has a positive test value, he/she should go to the hospital for early gastroscopy to rule out organic diseases and give regular anti-H. pylori treatment.
