Medical consultation, laboratory tests and sexual health advice are all free of charge at Clinic 275. A Medicare card is not required.

The Clinic has an onsite microscopy service. This means that we are able to provide some preliminary results on the day of your visit to the clinic.

Many common conditions can be accurately diagnosed during your visit, which means that treatment can be commenced without delay.

The emphasis of the clinic is on the diagnosis and treatment of sexually transmitted infections. It is not a family planning service so contraceptives, family planning advice and routine Pap smears are not offered.

HIV Point of Care Testing

Point of care (POC) testing for human immunodeficiency virus (HIV) is quick and convenient, providing results in 20 minutes rather than the next day. Some people refer to point of care testing as ‘rapid testing’.

Note: HIV POC testing is no longer available through Clinic 275. If required please see HIV Point of Care Testing page for more information.

Need a sexual health check-up?

The most common curable STI in South Australia is chlamydia. 
Chlamydia is most often a silent infection.

If you only have sex with people of the opposite sex in South Australia, and you have no symptoms, the infection you are most at risk of is chlamydia.

Here’s where you can get a check-up for chlamydia:

Confirmatory HIV test

Clinic 275 can offer you a confirmatory HIV test and result within 36 hours. Please ask one of the staff for more information at your next visit.

Speak to one of our staff and see if ChEx testing is suitable for you.
