STI testing: what to know
When testing matters, what a visit may involve, and why symptoms are unreliable.
No symptoms does not mean no infection
Many sexually transmitted infections can have no obvious symptoms. Testing is the only way to know your status for many infections. The right tests depend on exposure, body sites involved, timing and vaccination history.
What testing can involve
Depending on the test, a clinician may use blood, urine or swab samples. Ask what is being tested, when results will arrive and whether a repeat test is needed after a window period.
When to seek care
Speak to a qualified clinician after possible exposure, if a partner receives a diagnosis, before stopping barrier protection with a new partner, or if you notice pain, sores, discharge, rash, burning or other changes. Severe pain, heavy bleeding, fainting or suspected assault needs urgent care.
Privacy and partners
Clinics can explain confidentiality rules. If a test is positive, treatment and partner notification guidance depend on the infection. Avoid blame: testing is routine healthcare.
