Special instructions

If there is a chance that you have been exposed to HIV, hepatitis B or C then please let us know how long before taking your sample this occurred. Your sample should be taken 4 weeks after any hepatitis B exposure. Take your test at least 4 weeks after any possible HIV exposure, a repeat test is recommended at 12 weeks. Do not take biotin supplements for 2 days prior to this test. If you are taking prescribed biotin you should discuss this with your doctor. Avoid heavy exercise and eating meat-rich meals for 48 hours before your test.
PrEP (Pre-Exposure Prohylaxis), is a pill taken by HIV negative people to prevent them from being infected with HIV.

Before starting PrEP, it is important to have a test to check for certain health markers in the body. An HIV test is necessary as the medicines used for PrEP are also used for treatment for HIV, in differing doses. If you are already infected with HIV but aren’t aware, taking PrEP could cause you to become resistant to the medication, affecting your treatment for HIV.

A Hepatitis B test is also important because the medicines in PrEP are also used to treat Hepatitis B, so it may affect how you are advised to take PrEP. If you are infected with hepatitis B, you may need to see a liver specialist. It is also recommended to get a Hepatitis B vaccine if you have not had one, or a booster if you have.

Finally, this test includes an STI screen and checks your kidney function as PrEP can sometimes affect your kidneys, so it is important to check how well they are functioning.

You should also have testing every 3 months whist you are taking PrEP to check for HIV, STIs and kidney function. This test can also be used for regular monitoring for those currently taking PrEP.
