Just The Facts about Sexually Transmitted Infections

Getting tested for an STI

Talk to your healthcare provider about getting tested if:


  • You have had unprotected sex (i.e. without a condom or dental dam, or if the condom wasn't used properly);
  • You have a new sexual partner;
  • You have more than one sexual partner;
  • You're worried you've been exposed to an STI.

Not all STIs are prevented by the use of condoms. So, even if you used protection, it is a good idea to get tested if you notice any symptoms on yourself or your partner. If you have an STI and don't get treatment, you could pass it onto others, and it could cause more serious health problems later on. STI testing is often free, particularly for rangatahi.

What happens during an STI check?

You'll be asked about your sexual history.

The reason you're asked to provide this information is to help the doctor or nurse assess what tests or treatment you might need - it's not about judging you.


So that you get the healthcare you need, try to be as honest as you can. Remember, doctors and nurses will have treated hundreds of other people - they'll have seen and heard it all before!

How do they test?

The doctor or nurse should do a visual exam of your genitals to check for any physical signs of infection. Tests might involve a urine (pee) sample, blood sample, swab or examination - it's quick and easy.


If you have a vagina, they may take some swabs of your vagina. It might be slightly uncomfortable, but not painful. If it is painful, tell the clinician immediately.


If you have a penis, you will be asked to self collect a urine (pee) sample. They may swab your throat, penis or rectum, depending on the sexual encounters you’ve had as well as any symptoms you’re experiencing.

What do they test for?

An STI check tests for the common STIs.

- Chlamydia

- Gonorrhoea

- Trichomoniasis (this is not always included but can be done if requested). 


Ask what your STI check includes and does not include. A Syphilis and HIV test is not included automatically, but can be done if requested.

STI checks are confidential

No matter which doctor or nurse you see, an STI check is always private and confidential. You can also ask to see a female doctor or nurse if you prefer.

You might be asked to come back in at a later date

Sometimes a clinic might ask you to come back in a week or two to do a test. This is because some STIs don't show up on a test right away, so going for an STI test the day after unprotected sex might not give you a true result.
