What our users say

Great service. Removed an awkward barrier. I'm sure the service has helped many people test.


Extremely professional and efficient service. Very responsive. Open 7 days a week so great if you work long hours.


I think it is a great initiative. I've always wanted to know my status, but stigma and fear (especially in my home country) stopped me from getting tested. The privacy was comforting.


I usually need sedation for blood tests as I'm very anxious with blood. Intially found using the lancet hard to work up to, but was honestly thrilled I was able to do it myself! Great service. Thank you!


What's in the Insti HIV test kit?

For the instant HIV test, you need a single drop of blood from a finger prick. You’ll find an instruction card in your kit.

Read the instructions carefully. They tell you exactly how to do the test and read the results.

Insti test device

Put this on a clean flat surface.

Small lancets

Use a lancet to make a tiny cut in your fingertip.

Blood sample (bottle 1)

Let one drop of blood fall into the bottle. Twist on the cap. Shake the bottle 4 times and pour all the liquid into the test device. Wait until all the liquid has disappeared.

Testing solution (bottles 2 and 3)

Follow the instructions to pour the liquid from these bottles into the test device. First, pour all the liquid from bottle 2 and wait until it all disappears. Then pour in the contents of bottle 3. You’ll see your results in a few minutes.

Do not wait long to check your results. If you leave the test to develop for over an hour, the results will not be valid.

How to take a blood sample

You need a single drop of blood from your fingertip to take the Insti HIV test. Watch this short video to see how to do the test at home.

HIV: the basics

Prevent infection with PEP

If you think you may have been exposed to HIV in the last 3 days, go to your local sexual health clinic, or A&E department, immediately to get post-exposure prophylaxis (PEP).

PEP is a medication that can prevent infection even after you've been exposed, if taken within 72 hours. The sooner that you start this medication, the more likely it is to work.

When to test for HIV

HIV infection does not show in tests immediately, so you need to wait for the right amount of time to get an accurate result. The best time after risk to test depends on which types of HIV test you use:

  • HIV lab test: 7 weeks

  • Insti HIV test: 12 weeks (3 months)

  • OraQuick test: 12 weeks (3 months)

If you’re not sure when you might have been exposed, test now and do a second test in 7 or 12 weeks.

People can carry HIV without showing symptoms or knowing that they have it. So routine testing is important. If you have sex without condoms, particularly if you've changed partners, are a man who has sex with men, or have multiple partners, you should get tested for HIV every 3 months.

Treatment for HIV

Modern treatment means most people living with HIV have a long and healthy life. Treatment involves antiretroviral medications.

If your test gives a reactive result, one of our clinicians will call you to explain the next steps. We’ll help arrange another test to confirm your result.

Regardless of whether you have an infection or not, only our clinicians and service managers will see your test results.

All our staff sign a data protection agreement, similar to the ones used by NHS staff. Your results will never be shared with anyone else without your permission.
