HIV Test








HIV Detection and Antibody Testing

HIV (Human Immunodeficiency Virus) is a virus that targets the immune system, weakening the natural defences of the body and making it more prone to viral infections.

HIV Test

Our clinic is conveniently and centrally located in the heart of Harley Street, London’s historic medical district. We are within walking distance of Oxford Circus, Bond Street, Regent’s Street and Baker Street tube stations, and also accessible by dozens of bus routes. If you are coming by car, we are just 10 10-minute drive from Soho, Regent’s Park, Camden, Paddington, and Mayfair.

We have different testing options available depending on which HIV test makes the most sense for you. Some tests give results immediately (our instant HIV test gives results for antibodies in 60 seconds), while others take longer, and some tests are more appropriate in the case of recent possible exposure.

The HIV tests we offer are:

  • Instant HIV test
  • HIV antibody and P24 antigen
  • Multiplex (HIV, Hepatitis B, Hepatitis C) early detection
  • HIV-1 RNA fast early detection

For all of these, the test is a simple, relatively painless, blood test, using a small amount of blood. You may feel a slight pricking sensation when the sample is taken. To prepare for this test, please ensure that you arrive well-hydrated. The doctor will call you with your results as soon as they are ready. If necessary, a repeat visit, test or prescription will be arranged.



HIV is not spread through the air or through basic physical contact, unlike colds or flu. It is much harder to transmit HIV from one person to another. You can catch HIV from an infected person if certain of their body fluids get into your bloodstream. HIV is not transmitted through saliva, sweat, or urine.

The most common way to catch HIV is through unprotected sex (having sex without a condom). It is also spread by sharing needles or other injecting equipment with someone who is infected. It is also possible for an HIV-positive mother to pass the virus to her child during pregnancy, birth and breastfeeding. The virus is passed on through body fluids, but not through sweat, urine, or saliva. The only risk of transmitting HIV through kissing is if both partners have mouth sores or bleeding gums. This means that sneezes, coughs, sharing bath towels or cutlery, public toilets, swimming pools, or skin-to-skin contact (on healthy, unbroken skin) will not lead to HIV transmission.


HIV testing at our clinic

Our Harley Street walk-in clinic, located near Regent’s Street, Baker Street, Oxford Circus and Bond Street, offers HIV testing in a sensitive, professional and discreet environment.

We have a team of caring, experienced doctors and counsellors available on-site.

The cost of your test includes a short consultation, and any necessary prescriptions and a doctor will call you to go over your results.

We work with a leading laboratory to ensure excellence in testing and exceptionally fast turnaround times of 4-12 hours.

Body fluids capable of transmitting the infection

  • Blood
  • Semen
  • Vaginal fluid
  • Menstrual blood
  • Breast milk
  • Fluids found in the lining of the anus

HIV can infect the blood through several routes

  • The bloodstream (through contaminated needles or other equipment)
  • Through the lining inside the anus and genitals
  • Through the lining inside the mouth and eyes
  • Through cuts and sores

What to do next

An HIV test is the only way to know for sure whether you are infected with the virus. It is important to speak to a doctor as soon as you think you may have been exposed so that you can get tested. The kind of test you will take depends on the time that has passed since potential exposure to the virus, and involves giving a sample of your blood, which will be checked for signs of infection. Our London doctors can advise you on how best to proceed. Give us a call and make your appointment today.

  • Familiarize yourself with the different types of HIV tests available, such as antibody tests, antigen/antibody tests, and nucleic acid tests (NATs). Knowing the differences can help you understand what to expect.
  • The window period is the time between potential exposure to HIV and the point when a test can give an accurate result. Discuss with us the best time to take the test based on your last potential exposure.
  • Inform us about any medications or supplements you are taking, as some substances might interfere with the test results.
  • Unlike some other medical tests, HIV tests do not require fasting. You can eat and drink as normal before the test.
During the test
  • For most HIV tests, a small blood sample will be taken, either from a vein in your arm or a finger prick. The process is quick and usually only causes minor discomfort.
  • HIV testing is confidential. You will be asked for consent before the test, and your results will be kept private.
  • If you have any concerns or questions about the procedure or what your results might mean, don’t hesitate to ask the healthcare professional conducting the test.
  • You can choose how you would like to receive your results, whether by email, telephone, post, or in person.
  • If you do not wish to be contacted, we can arrange for you to call the clinic yourself to collect them.
  • The doctor or nurse is available to discuss the results with you as well.

I am concerned that I have been exposed to the HIV virus. What should I do next?
If your exposure has occurred within 72 hours, please find a GUM clinic such as Dean Street who can administer PEP. After this time, an HIV test is the only way to know for sure whether you are infected with the virus. We offer early detection testing at 10 days which is 99.9% accurate (HIV RNA test or HIV multiplex testing.) Standard HIV (4th generation) test is accurate at 6 weeks post exposure.
Seroconversion illness, which happens soon after exposure when your body is fighting the virus, typically lasts around 1–2 weeks. The most common symptoms of this are fever, sore throat, skin rash, accompanied by fatigue, joint or muscle pain, and swollen glands. These are common symptoms for many common conditions, however, and are not a sure sign that you have contracted the virus. An infected person can be asymptomatic (showing no symptoms at all) for many years.
Our early HIV detection test can give immediate peace of mind, but the doctor will normally recommend repeating with an HIV antibody test later on to be completed.
