Better2Know’s confidential and anonymous instant HIV test is available at sexual health clinics across the UK. Our test will bring you accurate results at just 26 days from any incident that you are concerned about. The test is performed by your Better2Know clinician while you wait. Results take around 20 minutes. Regular HIV testing is important to maintain your health and that of your partners.

Better2Know’s Instant HIV Test

At Better2Know’s conveniently located STI testing facilities, you will receive fast, accurate results for HIV with our instant test. Your personal information is completely confidential. You can remain completely anonymous and you do not have to give us your real name.

Better2Know’s instant HIV test uses your blood sample to detect the p24 antigen (a protein associated with HIV) and the HIV 1 and HIV 2 antibodies. If either of these are found by the test, it will show a reactive result.

When can I get tested?

You can receive confidential instant HIV testing as early as 26 days after an incident of concern. This period of incubation is recommended to ensure the accuracy of your rapid HIV results. If you choose to get tested before this suggested time has elapsed, then your HIV results may not be as accurate.

When will I receive my results?

You will receive your confidential results within 20 minutes after sample collection. You will be given a signed and completed copy of the Better2Know Rapid Test Results Report, outlining the results of your instant HIV test.

How accurate is my instant HIV test?

Better2Know’s private instant HIV test is highly sensitive and specific. The test is 99.8% accurate at 26 days post exposure.

What other STIs should I get tested for?

You can choose an instant HIV test on its own, or combined with other instant tests or laboratory based tests to create a more extensive screen. As well as HIV, you can also receive instant STI results for Chlamydia, Gonorrhoea, Syphilis, Herpes, Hepatitis B and Hepatitis C. Your Better2Know sexual health advisor will help you choose the most suitable testing options for your personal needs.

Attending Better2Know’s Private Sexual Health Clinic

Please attend your appointment on time. Your Better2Know clinician will greet you, and explain the instant HIV testing process to you, and then collect your samples.

Sample Collection and Analysis

Your clinician will collect a small blood sample for your instant HIV test. This will either be with a finger stick using a lancet or a normal blood sample. Your sample will be applied to the instant HIV test strip, along with a chase buffer solution. The test takes around 20 minutes to run.

If your test is negative for either the p24 antigen or HIV antibodies there will only be one line, in the control section of the test strip.

If you are reactive for the p24 antigen or HIV I/II antibodies, there will be two lines. A red line will appear in the relevant sections on the test strip, as well as the control line. We will then do confirmatory testing at our CPA accredited laboratory at no further cost to you.

HIV: Transmission, Symptoms, Treatment, Prevention

HIV Transmission

  • HIV is transmitted through the transfer of infected fluids including blood, semen, vaginal fluid, pre-ejaculate and breast milk.
  • Unprotected sexual intercourse with an infected person could also transfer to virus, including vaginal, anal or oral contact.
  • Acquiring or passing on HIV through oral sex is possible but rare.
  • Infected mothers can transfer HIV to their child either before or during birth.
  • Breastfeeding may enable the transmission of HIV to your baby.

HIV Symptoms

Signs of an HIV infection may not always be present in the early stages after exposure. If symptoms are present, they can occur in the first four to six weeks following infection. This is usually when your body has begun the seroconversion process. Seroconversion is where your body tries to counteract the virus by producing antibodies.

In the first four to six weeks, you may experience:

  • Fever
  • Fatigue
  • Sore throat
  • Swollen glands
  • Upset stomach
  • Rashes
  • Joint or muscle pain

Following this phase, symptoms can clear for up to 15 years, but you are still infectious, and the virus is still causing harm to your system. If you remain untreated, you will become more susceptible to other infections including bacterial, viral or fungal diseases.

Symptoms in the next stages of HIV infection may include:

  • Fever
  • Chronic diarrhoea
  • Weight loss
  • Night sweats
  • Persistent cough
  • Mouth ulcers
  • Skin conditions

HIV Treatment

If your instant HIV test is reactive further testing will be conducted. The first test will be a confirmatory test as no medical diagnosis should be based on one test. Any confirmation test is included in your Better2Know test.

If your confirmation test is positive, you will be referred to a specialist who will help to determine the right pathway for you. You will be asked to provide more blood samples to determine the effect of HIV on your system, before beginning treatment.

Treatment consists of antiretroviral medication. This inhibits viral replication, preventing further damage to your immune system.

HIV Consequences

If your HIV infection is left untreated, the reduction of your CD4 cells will affect your immune system. This means it will be harder to fight infections, and other diseases. Eventually you will develop an AIDS-defining illness, leading to a diagnosis of AIDS, which can be fatal.

HIV Prevention

  • Use a condom
  • Test regularly
  • Encourage your partners to test regularly
  • Do not have unprotected sex with high risk people
  • Do not share needles

Testing for HIV regularly ensures an infection is not left undiagnosed or untreated.

It is important to notify recent sexual partners if you test positive for HIV. This prevents further transmission and enables earlier treatment if they have been infected. You can use the Better2Know partner notification system in your patient area to notify your partners.

If you think you may have been exposed to HIV, post-exposure prophylaxis (PEP) could prevent you from being infected. PEP medication is usually only available following high risk exposure. It must be started within 72 hours of direct contact with the virus.

For those at high risk of infection, pre-exposure prophylaxis (PrEP) is available to also reduce the chances of contracting HIV. This medication must be taken every day, and helps to prevent you becoming HIV positive.
