There is no single right answer to how often you should test for sexually transmitted infections — it depends on your situation, not on any judgement about your choices. Sexual health testing is a routine, sensible part of looking after yourself, much like checking your blood pressure or having a dental check-up. The aim of this guide is simply to help you decide what makes sense for you.
A sensible baseline for most people
If you are sexually active, a good general rule is to have a full STI screen at least once a year, even when you feel completely well. Many common infections cause no symptoms at all, so an annual check is the most reliable way to catch anything early and put your mind at rest.
Beyond that yearly baseline, the right frequency depends on a few practical factors that are worth thinking about honestly and without embarrassment.
When to test more frequently
Some circumstances make more regular testing a good idea. Consider getting checked:
- With any new partner — testing before or early in a new relationship protects both of you.
- If you have more than one partner — every three to six months is a reasonable rhythm.
- After unprotected sex — particularly if you are unsure of a partner's status.
- If a partner tells you they have tested positive for an infection.
- Before stopping condoms with a regular partner, so you both start from a clear picture.
Do not wait for symptoms
It is a common misunderstanding that you only need a test if something feels wrong. In reality, chlamydia, gonorrhoea and several other infections are frequently silent. Testing without symptoms is not over-cautious — it is simply how these infections are most often found, and it is entirely normal to book a check purely for reassurance.

A screen is quick and low-key. Depending on the infections checked, it may involve a small blood sample, a urine sample or a self-taken swab. There is no need to explain your reasons to anyone, and your results are kept private. Most people find the process far easier and less awkward than they expected.
When to get tested
Book a screen if you have started seeing someone new, if it has been more than a year since your last check, if a partner has been diagnosed, or simply if you would feel better knowing. If you have symptoms such as unusual discharge, pain when passing urine, or sores, arrange a test sooner rather than later. Whatever the reason, getting checked is a positive, responsible step — never something to feel awkward about.
