Sexual Health > HIV Test
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.
Therefore, knowing your HIV status is crucial. We have different HIV testing options available (with no hidden charges), depending on which HIV test makes the most sense for you. Some tests give results immediately, while others take longer. Additionally, some tests are more appropriate in the case of recent possible exposure.
Human Immunodeficiency Virus (HIV) is a virus that attacks the body’s immune system, specifically the CD4 cells (T cells), which are crucial for immune response.
Over time, HIV can destroy so many of these cells that the body cannot fight off infections and diseases, leading to the most severe phase of HIV infection: Acquired Immunodeficiency Syndrome (AIDS).
HIV is diagnosed using blood or saliva tests. We offer an Instant HIV test, HIV antibody and P24 antigen test, Multiplex (HIV, Hepatitis B, Hepatitis C) early detection test, and HIV-1 RNA fast early detection test. All of these tests are a simple, relatively painless, blood test.
Acute HIV Infection: This occurs within 2 – 4 weeks after exposure to the virus. During this time, some people may experience flu-like symptoms, which is the body’s natural response to the infection.
Chronic HIV Infection: Also known as asymptomatic HIV infection or clinical latency. During this phase, HIV continues to multiply in the body at low levels but may not cause any symptoms. Without treatment, this stage can last a decade or longer, but some may progress through it faster.
AIDS: This is the final, most severe phase of HIV infection. By this stage, the immune system is badly damaged, and the body becomes vulnerable to opportunistic infections and certain cancers. Without treatment, people with AIDS typically survive about three years.
Unlike colds and flu, HIV is not spread through the air or through basic physical contact. You can catch HIV from an infected person if certain of their body fluids get into your bloodstream. Body fluids capable of transmitting the infection include blood, semen, vaginal fluid, menstrual blood, breast milk, and fluids found in the lining of the anus. HIV is not transmitted through saliva, sweat, or urine.
The most common way to catch HIV is through unprotected sex. 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.
To prevent the transmission of HIV, it is imperative to practice safe sex (using condoms), get regular HIV testing, know your partner’s HIV status, and use pre-exposure prophylaxis (PrEP) if you are at high risk of HIV.
You must definitely avoid sharing needles and syringes, and always go to reputable hospitals where safe blood transfusions and organ transplants are ensured.
While there is no cure for HIV, it can be controlled with proper medical care. The main treatment is antiretroviral therapy (ART), which involves taking a combination of HIV medicines every day.
ART helps reduce the viral load in the body to undetectable levels, allowing people with HIV to live longer, healthier lives and reducing the risk of transmitting the virus to others.
Our clinics, established in 1998, offer expert testing, in-depth consultations, clear explanations of treatments moving forward, and personalised patient care. Because at the heart of what we do is always you, our patient, and your wellbeing.
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.
Boosting your immune system when living with HIV involves a combination of medical treatment, lifestyle changes, and self-care strategies. Here are several key approaches:

As an international visitor, I was very grateful for the prompt attention to my request for an appointment. Dr Ali was respectful and empathetic in regard to my condition and suggested further treatment, which I was able to organise for the next day. Both offices I attended treated me appropriately and I would recommend Harley Street Health Walk-in Clinics to anyone visiting London who requires medical attention.Posted on Trustindex![]()

Highly recommend City Walk-In Clinic Really pleased with my experience at City Walk-In Clinic. I booked a female hormone test because I wanted some answers about a few symptoms I'd been having, and the whole process was straightforward. The staff were welcoming, friendly and didn't make me feel rushed at all. The blood test was quick, and they explained everything clearly before taking the sample. My results came back sooner than I expected, and it was reassuring to have everything presented in a way that was easy to understand. I'd definitely use the clinic again and would recommend it to anyone looking for a private female hormone test. Professional service, lovely staff and an all round positive experience.Posted on Google![]()

I had a private gp appointment yesterday as my feet have been swelling every day over the past few days. So I booked an appointment with Dr Heather. Dr Heather explained the possible causes of the swelling, including the heat that we are currently experiencing in London. Recommended further investigation if the swelling persists, to identify the underlying issue rather than just making assumptions.Posted on Google![]()

I have used City Walk In Clinic as my go to place for routine blood tests. My recent full health check gave my doctor some clues that i may be approaching my menopause era. So my doctor has recommended that i do some tests to find out if indeed i am entering perimenopause, as the symptoms are there. Will be having my tests in the next few weeks. So glad i had a full health check, because all these symptoms were driving me crazy.Posted on Google![]()

I attended The Harley Street Walk/in centre in the City recently. I was able to book my appointment the day before for a blood test at a time that suited me. The booking process was straightforward. The doctor that conducted the venous draw was efficient and very pleasant. I have never had such a painless venous draw and I have had many! My appointment was at 5pm and I had my results before 8 am the following day. I will be very happy to book my tests here in the future. Thank you.Posted on Google![]()

I wanted a cholesterol check up and chose this clinic because it seemed to offer a competitive price for a detailed report. And so it turned out to be. Received a prompt and professional service at a price that was significantly less than other nearby providers in central London. I have now used it twice and would definitely recommend.Posted on Yell![]()

The Walk-In Clinic in central London exceeded my expectations in every way. Their attention to detail and commitment to tailored care for their patients truly sets them apart. The availability of evening appointments until 6:30 pm was a game-changer for someone like me juggling multiple commitments.Posted on Yell![]()
