When should you test?
STI testing makes sense in several scenarios. Not sure? Run the advisor for concrete guidance.
- After unprotected sexual contact with a new or changing partner
- When you have symptoms such as discharge, painful urination or skin issues
- Before starting a new relationship (getting tested together)
- Periodically if you belong to a risk group (e.g. MSM or sex work)
- After a needlestick or blood contact incident
- When a partner tests positive
About the window period
An STI isn't always immediately detectable. The window period is the time between infection and when a test can reliably confirm it.
For HIV this is roughly 6 weeks with a modern combination test. For chlamydia and gonorrhoea about 1–2 weeks. The advisor factors this in and suggests a retest if needed.
