PrEP (pre-exposure prophylaxis) is a medication that can lower your chances of getting infected with HIV, if you have a higher risk. You need to take certain tests to be prescribed PrEP. You can order any PrEP test kits you need through ZAVA.

Before taking PrEP

Before we can prescribe PrEP to you, we’ll ask you whether you've had a:

  • negative HIV test result
  • normal kidney function (creatinine and estimated Glomerular Filtration Rate; eGFR) test result
  • negative hepatitis B and C test result — you only need a negative hepatitis B result if you’ve not had a hepatitis B vaccination, and you only need a negative hepatitis C result if you are a man who has sex with other men or are a trans woman

We offer 2 introduction test kits. Order our:

  • basic PrEP test to check your HIV status and kidney function only, if you know your hepatitis status or have had a hepatitis B vaccination already
  • comprehensive introduction PrEP test* to check all the above (HIV status, kidney function, and hepatitis B and C status)

Every 3 months, you need a:

Once a year, you need a:

  • negative HIV test result
  • normal kidney function test result — if you’re over 40 years old or have a high risk of kidney disease, you should check this every 6 months instead
  • negative hepatitis B and C test result

We offer 2 continuation test kits depending on which stage you’re at and the tests you need. Order our:

We also offer standalone HIV tests and kidney function tests.

*Important: If you have a hepatitis B vaccination, you should wait 8 weeks before taking a hepatitis B test. You may get a false positive result if you take this sooner.

STI screening (optional)

It's also recommended that you do a full screen to check for STIs (sexually transmitted infections), both before and while taking PrEP.
