Need help with your SHL.UK testing kit?
My kit has not arrived
Our test kits are sent by Royal Mail first class post. Most test kits arrive within 1-3 working days, however there are sometimes delays.
If more than 7-10 working days have passed and your kit has not arrived, please Contact Us.
When your kit arrives
Take a few minutes to look through the contents and read the guidance sheet.
Collecting your samples shouldn’t take too long and we are here if you need support.
When should I take my samples?
It’s best to take your samples and post them Sunday-Thursday, because they will reach our lab and be tested more quickly.
It takes some time from catching an infection before it shows up on a test, this is called a window period.
The window periods we recommend are:
- Chlamydia and Gonorrhoea: 2 weeks after last exposure
- HIV: 8 weeks after last exposure
- Syphilis, Hepatitis B and Hepatitis C: 3 months after last exposure
If there is a chance you have been exposed to an STI it can still be worth taking a test during the window period. That way, if you do test positive, you can begin treatment straight away. But if you test negative, please do another test at the end of the window period.

How will I receive my test results?
Most people will get a message to login and check their results. However, in some cases an NHS clinician will call to discuss your test results and treatment.
To learn more about the different results, please go our page: What do my results mean?
How accurate are the results?
Our tests are highly accurate when done at the right time.
Although no STI test is 100% accurate, we use the gold standard for testing. All tests are processed in-house, as we run the UK’s leading STI laboratory, which also deals with thousands of STI tests every day for the NHS and local sexual health services.
You can help to make your test as accurate as possible by following the instructions carefully when taking your samples.
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 reactive results are rare but do happen.
