When should you consider getting tested?
Consider testing after a new partner, unprotected sex, or if a partner has an STI. See a clinician if you have symptoms.

Situations where testing is sensible
The NHS suggests testing if you have had unprotected sex, a new or multiple partners, or a partner who has an STI or symptoms. Many people also test as part of routine self-care, for example before stopping condom use with a new partner.
Timing
Some infections take time to become detectable. Kit instructions explain how long to wait after possible exposure. Testing too early can give a negative result that needs repeating.
When to go straight to a clinic
Seek clinical care rather than a home test if you have symptoms, are pregnant, may have been exposed to HIV in the last 72 hours, or have been told a partner has an infection.
