Thank you for viewing! This is a test kit that allows you to easily check for the presence of Helicobacter pylori (H. pylori) at home. I accidentally purchased it and it went unused, so I am offering it for sale. The following is a product description: H. pylori test (fecal H. pylori antigen qualitative test) ・Checks for H. pylori infection, which is said to be a major factor in the risk of stomach cancer. It is said that over 90% of stomach cancers are caused by long-term atrophic gastritis due to H. pylori infection. By checking for the presence of H. pylori infection and performing eradication treatment on infected individuals, the risk of stomach cancer can be significantly reduced. Testing method: 　Collect stool in the "stool collection container" and send it from the post office. 　The results will be sent as a PDF file via the postal test kit center email 2-4 business days after the sample arrives. 　■Fill out the questionnaire and collect a stool sample according to the instructions. 　　⇒Return the stool collection container and the completed questionnaire. 　■Send it from the post office or a post box. 　(Postage is not required) ⇒ Please ship it promptly after collecting the stool sample. 　■The results will be converted into a PDF file and sent via email 2-4 business days after the sample arrives. If the test results are abnormal, we will consider submitting them to a medical institution and will send them by Japan Post's special delivery or registered mail along with the email.
