H. pylori staining solution is usually able to detect H. pylori. H. pylori staining solution is a rapid test for H. pylori and is relatively accurate, but it is usually necessary to combine it with other results. Any test method has sensitivity and specificity, and false-positive or false-negative results may occur. Therefore, the diagnosis should be confirmed by further tests, such as breath test, blood sampling for H. pylori antibodies, detection of H. pylori antigen in stools, or combining with the biopsy results of gastroscopy and the clinical manifestations, etc., in order to allow early diagnosis and treatment. If the results of H. pylori tests are abnormal, it is recommended to go to a regular hospital in time, to clarify the cause of the disease, and then carry out targeted treatment or therapy under the guidance of the doctor.
