STI Health Check | Geschlechtskrankheiten-Test: what can you do yourself?

For an STI health check, there are several things you can do yourself, but with important caveats. Home test kits for common STIs like chlamydia, gonorrhea, syphilis, HIV, and trichomoniasis are available over the counter or online. They typically use urine samples or self-collected swabs and can provide initial results. However, sensitivity varies; false negatives are possible, and a positive result always requires confirmatory testing by a healthcare professional. You can also monitor your own symptoms (discharge, burning, sores), but many STIs are asymptomatic. Prevention through consistent condom use and regular testing (every 3–12 months depending on risk) is the most effective self-action. Important: Self-tests do not replace a doctor's diagnosis or treatment. If you test positive or have symptoms, seek medical care promptly. Evidence for self-testing is mixed: strong for HIV and syphilis, moderate for chlamydia and gonorrhea, and weaker for others. Overall, self-tests are a useful screening tool but not a substitute for professional healthcare.
