STI Test: when to see a doctor?

The question of when to see a doctor for a suspected STI is clinically important, but the provided context contains no specific information about STI testing. In general, you should see a doctor if you have symptoms such as discharge, burning, pain, or genital sores. Also, after unprotected sex with a partner of unknown STI status, a consultation is advisable even without symptoms. At-home STI tests can provide initial screening but are not a substitute for professional diagnosis and treatment. A positive result requires confirmatory lab testing and medical follow-up. The evidence for these recommendations is based on clinical practice guidelines, not on product-specific studies. Since the context lacks STI-specific products or data, the evidence is graded as 'practice'. Caveat: Delayed treatment can lead to complications such as infertility or chronic infections.
