About the tests
What do these tests actually detect?
They screen for antibodies your immune system produces in response to herpes simplex virus — HSV-1, HSV-2, or both, depending on the kit. They do not detect the virus itself.
What is the difference between the HSV-1, HSV-2 and Combined kits?
The HSV-1 and HSV-2 kits each screen for one antibody type. The Combined kit screens for both in a single test, reading each type separately.
Is a home test a diagnosis?
No. These kits are for screening only. They do not diagnose disease and are not a substitute for professional medical advice or laboratory testing. Any reactive result should be confirmed by a clinician.
Accuracy & results
How accurate is the test?
We publish the manufacturer's performance figures for each kit exactly as stated in its instructions for use. No screening test is 100% accurate, and we will never claim otherwise.
What does a reactive result mean?
It means antibodies may have been detected. It is not a diagnosis. Contact a healthcare professional, who can arrange confirmatory laboratory testing and advise on next steps.
Can I get a false result?
Yes — like all screening tests, false positives and false negatives are possible. Testing during the window period soon after exposure is a common cause of a falsely non-reactive result.
What is the window period?
After exposure it takes time for detectable antibodies to develop. Testing too soon can miss a recent infection. Follow the timing guidance in your kit's instructions.
Using the kit
How long does it take?
You read the result after the wait time stated in your kit's instructions. The active steps take only a few minutes.
What if no control line appears?
The test is invalid and cannot be read, whatever the test line shows. Repeat with a new kit, following the instructions carefully.
What if the test line is very faint?
A faint test line still counts as a reactive result. Treat it as reactive and confirm with a healthcare professional.
Ordering, delivery & discretion
Is my order discreet?
Yes. Orders arrive in plain, unbranded packaging with no product name on the outside and a neutral sender name on the label.
Where do you ship and how long does it take?
Orders are dispatched from the UK. Delivery timeframe and cost are shown at checkout. Timeframe TBC
Can I return a kit?
Your statutory rights under UK consumer law apply. Note that specific rules apply to opened sealed medical or hygiene items — see our Returns and Refund pages. Wording pending legal review
Privacy & data
Do I enter my result on your website?
No. You read your result yourself, at home. Your result is never entered on this site.
How is my personal data handled?
We process personal information in line with UK GDPR, use encrypted checkout, and do not sell your personal data. See our Privacy Policy for full detail.
When to see a doctor
When should I seek professional care?
Contact your GP or a sexual health service if you have a reactive result, have symptoms, have had a recent known exposure, or are unsure about your result. In the UK you can call NHS 111 for non-emergency advice.
Who should not rely on this test alone?
Anyone with symptoms, a recent known exposure, or a specific medical concern should seek professional care rather than relying on a home screening test.
