One of the most common questions people ask about sexual health is also one of the least clearly explained: how often should I actually be tested?
The answer depends on exposure — not judgement, symptoms, or assumptions.
What Australian guidelines say
According to the Australian STI Management Guidelines and RACGP, STI testing is recommended:
-
At least once a year if sexually active
-
After every new sexual partner
-
If a partner tests positive
-
When planning pregnancy
-
If you have never tested
These recommendations apply regardless of symptoms.
Why testing frequency is based on exposure
STIs are transmitted through contact, not behaviour labels.
Guidelines focus on exposure because:
-
Many STIs are asymptomatic
-
Early treatment prevents complications
-
Routine screening reduces community transmission
Waiting for symptoms delays care and worsens outcomes.
Relationship status and testing
Being in a monogamous relationship may reduce risk, but it does not eliminate it.
Testing is still recommended:
-
At the start of new relationships
-
If agreements change
-
If there is uncertainty
Testing is about shared responsibility, not distrust.
STI testing vs cervical screening
These are often confused, but they serve different purposes.
-
STI testing looks for current infections
-
Cervical screening detects cell changes caused by HPV
You can be up-to-date with one and still need the other.
Making testing realistic
Public health evidence shows people test more consistently when:
-
Access is easy
-
Appointments are flexible
-
Care feels non-judgemental
Reducing friction improves outcomes.
The bottom line
If you’re unsure when you last tested, you’re not alone.
What matters is having access to clear guidance and supportive care — not getting it “perfect”.
