Before Taking PrEP

Before starting on PrEP you’ll require a few tests:


  • A full sexually transmitted infections (STI) screen. It is recommended to have a full STI screen every 3 months – even if you don’t have any symptoms.
  • An HIV antibody antigen test at your local clinic. These tests have a much shorter window period than other tests – they can give an accurate result 4 weeks after potential exposure to HIV.
  • A blood test to check your kidney function. In a very small number of people PrEP can damage renal (kidney) function. This is rare and usual only in people with existing kidney problems or taking other medication that may affect their kidneys.
