Order a Test Kit

This is a free and confidential service for Bristol, North Somerset and South Gloucestershire,

You can request a free test kit if you are 16 years old or over and live in Bristol, North Somerset and South Gloucestershire ONLY. 

This service is available to people without any symptoms. If you have symptoms we would prefer to see you at one of our clinics as we have more tests and treatments available.  Information can be found here. If you have had syphilis treated in the past, the blood test on the postal kit will not be able to give us enough information and you should attend a clinic in person for testing.

You will need to provide a mobile number. Any information that you share will remain confidential within Unity.

The kits will be sent to you in a blank envelope with no reference at all to sexual health or testing. It might take up to 2 weeks to arrive in the post and results are available up to 15 working days after you send back your completed kit.


The kit tests for chlamydia and gonorrhoea. The blood sample is tested for HIV and syphilis.


If you have any difficulties with the blood test, please check out our video below.

There can sometimes be a delay before a test becomes positive after you have had sex.  This is often referred to as the “window period” for testing.

  • Chlamydia and gonorrhoea – the window period is 2 weeks;
  • HIV – the window period is 4 weeks;
  • Syphilis – the window period is 12 weeks.

If you live in Bristol, North Somerset or South Gloucestershire and your post code is not accepted when you put in in please call us on 0117 342 9299 and we can add it to the system.

For further instructions and advice on your Unity postal kit, please see our Postal kit FAQs page.
