The Annual Continuation PrEP test is a test that you can use to test your HIV status, kidney function (creatinine and estimated Glomerular Filtration Rate; eGFR), and hepatitis B and C status.
If you have been taking PrEP for a year, you need to take this test to make sure that we can continue to prescribe your PrEP. You should only take this test if you are already taking PrEP. If you are new to PrEP and would like to start taking it for the first time, you should take the Comprehensive Introduction PrEP test.
If you’ve recently received a hepatitis B vaccination, you should wait 8 weeks before taking this test. You may get a false positive result if you take this test sooner.
After completing this test our doctors will know if it’s still suitable for you to continue taking PrEP. You must take this test every year if you want to continue taking PrEP.



About the test kit
-
-
This test kit is for people who have already been taking PrEP for a year. It will tell you your HIV status, kidney function (creatinine and estimated Glomerular Filtration Rate; eGFR), and hepatitis B and C status.
If you have not taken PrEP before you should take the Comprehensive Introduction PrEP test. If you have only been taking PrEP for three months, you should take our 3-month Continuation PrEP Test.

-
You need to take this test once a year to make sure it’s still suitable for you to take PrEP.
You should also wait 8 weeks after a hepatitis B vaccination before taking this test. You may get a false positive result if you take this test sooner.
If you don’t take this test or decide you want to stop taking PrEP, you will need to take the Comprehensive Introduction PrEP test again if you want to start taking PrEP again.

Your results will tell you whether it’s still suitable for you to take PrEP. If this is the case, you can place an order for PrEP straight away.
If your results say that you cannot take PrEP, this means that you’ve tested positive for either HIV, reduced kidney function or hepatitis B or C.
This will be clearly explained in your results, and you’ll be given information on precisely what to do next. You’ll also be able to book a follow-up telephone consultation with one of our doctors.

You should only take this test if you’re already taking PrEP and want to make sure it’s still suitable for you to continue taking PrEP.
If you have not taken PrEP before and want to start taking PrEP, you need to do either our Comprehensive Introduction PrEP test or our Basic PrEP test (if you know your hepatitis status).

If your HIV test kit comes back positive our doctors will be on hand to help. All positive results must be followed up by another test using different technology.
If you do test positive for HIV one of our doctors will discuss all possible consequences with you in detail. We’ll also help you to find specialist care in your local area and put you in touch with local support groups.
