H. pylori test strips are available at drugstores, and there are common test strips for oral and fecal testing. The drugstore test strips are easy to use and can detect H. pylori infection in about 15 minutes. If the test is positive, it indicates infection; otherwise, there is no H. pylori infection. However, test strips purchased at drugstores come from different manufacturers and vary slightly in quality, which may cause inaccurate test results. Test strips approved by the State Food and Drug Administration (SFDA) can ensure quality. If you are infected with H. pylori and it is not detected, it may aggravate your condition. If there is no infection but H. pylori infection is detected, taking medication arbitrarily may also adversely affect the body. Patients are advised to go to the hospital for a breath test, gastroscopy, etc. for more accurate results. If you need to test whether you are infected with Helicobacter pylori, you should purchase regular products for use under the guidance of your doctor, and choose the appropriate test method according to your condition. Do not buy at random to avoid adverse effects.
