When testing for H. pylori by the H. pylori antibody method, a combination of positives and negatives should be used to determine the presence of H. pylori, with positives indicating a current or previous H. pylori infection and negatives indicating normal. The H. pylori antibody test is a blood test that detects antibodies to H. pylori in the blood to reflect the presence or absence of H. pylori, with a positive test belonging to a current or previous H. pylori infection. The use of H. pylori antibody test in the clinic is gradually decreasing because the antibody will exist in the body for a longer period of time after H. pylori is eliminated, resulting in the antibody test being prone to false positives, which is not conducive to diagnosis and treatment. Nowadays, the commonly used clinical testing methods include carbon 13, carbon 14 urea breath test, rapid urease test, microscopic examination of stained sections of gastric mucosa, bacterial culture and so on. If you suspect that you are infected with Helicobacter pylori, you should go to a regular hospital in time, test and diagnose with the help of a doctor, and carry out targeted treatment, do not take medication on your own.
