What role does STI Test play in Haut?

STI tests (sexually transmitted infection tests) play a key diagnostic role in dermatology when skin changes such as genital warts (HPV), ulcers (syphilis, herpes), or rashes (HIV exanthem) are present. However, they are not a general skin screening tool. Most skin conditions (acne, rosacea, eczema) are unrelated to STIs. An STI test is only indicated when there is specific risk or symptoms. The evidence for broad STI screening in asymptomatic individuals is moderate and depends on prevalence. Caveat: A negative STI test does not completely rule out an infectious cause of skin lesions (e.g., seronegative window). The MyBody-X DNA tests from the context (e.g., rs601338, rs1800795) have no direct link to STIs. In summary, STI tests are a specific diagnostic tool, not part of general skin assessment.
