How SH:24 testing works

  1. Order through our website - we’ll ask you a few questions so we know which kit to send you.

  2. Your test kit arrives in the post - our STI tests are delivered in a plain, letterbox-friendly pack, delivered by Royal Mail.

  3. Take your samples - inside the kit you’ll find everything you need to take some samples at home. Set aside 10 minutes to do the kit, and read the instructions carefully before you start.

  4. Post them back - post your samples to our lab on the day you take them, from any Royal Mail postbox.

  5. Results and support by text - when your samples reach our lab, you’ll get a text letting you know. You’ll usually get your results - in a text message - within 72 hours of your samples arriving. We might ask to call you to talk about your results. Our clinical team are only a text away if you have any questions or need further support.

  6. If you get a positive result - we’ll help you get the treatment you need. In some regions, we can send you treatment for chlamydia through the post.

If our free service is not available in your area, you can contact your local NHS sexual health clinic. Or you can buy STI test kits from .

What’s in the kits?

When you order, we’ll let you know what samples you’ll need to take to get tested. Our kits will test for the most common STIs using a blood sample, a urine sample or a vaginal, throat or rectal swab.

The kit we send you is based on the answers you give when ordering a kit plus national testing guidelines.

All kits come with everything you need to take your samples and post them back to us. Including full instructions, helpful tips and advice and a Freepost pack for returning them.

Make sure you read the instructions before taking any samples.

Blood sample

This is a finger-prick blood sample that can be tested for HIV, syphilis, hepatitis B and hepatitis C. We’ll send you some lancets and a sample tube. Use a lancet to make a small puncture in your fingertip and collect 15 drops of blood in the tube.

Urine sample

If you have a penis, we’ll ask for you to send a urine sample to the lab so we can test for chlamydia and gonorrhoea.

Vaginal swab

If you have a vagina, you’ll need to collect a sample by wiping this swab inside your vagina. We test this for chlamydia and gonorrhoea.

Rectal swab

Gonorrhoea and chlamydia can be passed on during anal sex. If we need to check for infections in your anus, we'll include a swab in your kit so you can take a sample from your anus.

Throat swab

It can be possible to get gonorrhoea or chlamydia in your throat. If we send you a throat swab, you'll need to take a sample from the back of your throat to test for these infections.

Getting your test results

Once you’ve posted your samples back to our lab in the Freepost pack, we’ll keep you updated by text message.

You’ll get a message when your samples arrive at the lab, and we’ll text you your results as soon as possible, usually within 72 hours. If there’s a delay, we’ll let you know.

We may need to call you to talk about your result. If we do, we’ll always text you first to arrange a time that suits you.

How do I get treatment?

If you have an infection, our clinical team will help you get further support and treatment. In certain regions, we can send you chlamydia treatment by post, or we can help you find a sexual health clinic that can treat your infection.

If your test result for HIV, syphilis, hepatitis B or C comes back as reactive or postive, our clinical team will support you to get further tests.

When do STIs show in tests?

Most STIs don't show in a test straight away. So you need to wait a few weeks before a test will be accurate. This time is called the window period. The window periods are different for different infections.
