An STI test (sexually transmitted infection test) is not designed to assess gut health. STI tests detect pathogens such as chlamydia, gonorrhea, or HIV, which are primarily transmitted through sexual contact. While some STIs (e.g., Chlamydia trachomatis) can cause proctitis, this is a specific condition, not general gut health. For persistent digestive issues like bloating, diarrhea, or abdominal pain, stool analysis, food intolerance testing (with caution, as IgG tests often lack validity), or a medical evaluation are more appropriate. An STI test provides no relevant information for gut health and may lead to false reassurance or unnecessary anxiety. Evidence for using STI tests in this context is absent.
