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.

Therefore, knowing your HIV status is crucial. We have different HIV testing options available, 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.

Understanding HIV

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.

Stages Of Infection

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.

Causes Of HIV

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.



Preventing The Disease

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.

Treatment For HIV

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.

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.

The Procedure

preparing for appointment


  • Familiarise 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 appointment


  • 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.

post appointment


  • 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.
What are the symptoms of HIV?
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.
Will I need repeat tests?
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.
