STI home testing FAQs

How will I receive my results?

Most people will receive their results by text message. However, in some cases an NHS clinician will call to discuss your test results and treatment.

Will my results be shared with anyone else?

Your results will never be shared with anyone else, in or outside the NHS, without your permission.

How accurate/reliable are the results?

No STI test is 100% accurate. It can take time for some STIs to show up in tests, so find out when STIs show up in tests before you take one.

The SH:24 laboratory works to strict, government enforced protocols to ensure results are as accurate as possible. If you have any concerns about the reliability of your results, we would be happy to talk to you.

A test result that shows a possible infection is called 'reactive'. For HIV testing, a 'reactive' test will require further investigation to confirm the result. False reactives are rare but do happen.

If I have an STI will I have to go to a sexual health clinic?

If you have an infection you may need to visit a clinic to receive treatment. A clinician will be available to discuss your treatment with you.

When should I just to straight to a clinic?

We would strongly recommend that you visit a clinic as soon as you can, if one or more of the following applies to you:

  • If you have been sexually assaulted
  • If you are a man who has sex with men and have had unprotected sex in the last three days
  • If you have any symptoms
  • If you are a woman and have had unprotected sex in the last five days and think you are at risk of being pregnant
  • If you are under the age of 16.

Do I have to order the test to my home?

No - the test does not have to be delivered to your home, though this is the fastest way to get it.

If you would prefer to have your test delivered to a friend's house, workplace or other location please put that as the delivery address. However, please note that free tests are only available to residents of Cornwall and the Isles of Scilly and can only be sent to addresses within those locations.
