Testing For HIV, Hepatitis B & C

The multiplex early detection test can be administered soon after potential exposure to infected blood. It functions by amplifying minute amounts of genetic material in a sample to a detectable level, enabling the identification of even trace amounts of the target organism.

Multiplex testing stands out as the most accurate method currently available for detecting HIV, Hepatitis B, and Hepatitis C. Our City Walk-in Clinics offer transparent pricing for all our tests, backed by years of experience to ensure you are in the safest and most secure hands.

Doctor considering blood test options

Multiplex Early Detection Overview

The multiplex test is a blood test, and is sometimes also referred to as a PCR test (Polymerase Chain Reaction), or NAAT (Nucleic Acid Amplification), which works by analysing DNA to detect tiny amounts of viral genetic material.

This test can be taken soon after exposure to the HIV virus (minimum of 10 days), as early detection is key in preventing the spread of these infections and ensuring effective treatment.

How The Test Works

Multiplex Testing uses a multiplex technology that allows simultaneous detection of multiple markers to detect and measure multiple antibodies, antigens, or nucleic acids in a single blood sample.

A healthcare professional collects a small sample of blood, usually from a vein in the arm. The collected blood sample is processed in a laboratory where trace amounts of DNA from the sample are then amplified and compared to the virus’ own unique DNA sequence.

The test is highly sensitive and highly accurate, and your results will be available within a week.

Who Is The Test For?

The Multiplex HIV and Hepatitis Early Detection Blood Test is beneficial for the following groups:

  • High-Risk Individuals: People who engage in behaviours or have occupations that increase their risk of infection, such as intravenous drug users who share needles, individuals with multiple sexual partners, people with partners known to be infected with HIV, Hepatitis B, or Hepatitis C, and healthcare workers.
    Pregnant Women: Early detection is crucial to prevent mother-to-child transmission of these infections.
  • Patients With Symptoms Or Known Exposure: Individuals showing symptoms of these infections or who know they have been exposed to the virus.
  • Immigrants From High Prevalence Areas: People coming from countries with high rates of HIV, Hepatitis B, or Hepatitis C.

Benefits Of Testing

The benefits of getting a Multiplex Test include:

  • Early Detection: The test allows for the early detection of infections, often before symptoms appear. This can lead to earlier intervention and treatment, improving health outcomes.
  • Comprehensive Screening: It simultaneously screens for HIV, Hepatitis B, and Hepatitis C, providing a comprehensive assessment of potential blood-borne infections in a single test.
  • High Accuracy: Multiplex testing is highly sensitive and specific, reducing the likelihood of false negatives and false positives.
  • Prevention Of Transmission: Identifying infections early helps prevent the spread to others, particularly in high-risk populations or situations where individuals might unknowingly transmit the virus.
  • Informed Decision-Making: Knowledge of one’s infection status enables informed decisions regarding lifestyle, sexual practices, and health care, reducing the risk of further complications.

Steps To Take After A Positive Test Result

When you test positive for HIV, Hepatitis B, or Hepatitis C using a Multiplex Early Detection Blood Test, several steps follow to confirm the diagnosis and begin appropriate management.

Additionally, a comprehensive medical evaluation will be carried out to assess your overall health, the stage of the infection, and any complications. This includes physical exams, additional blood tests, and possibly imaging studies.

A treatment plan will be created to ensure your infections and disease are successfully and effectively managed. Counselling services will be offered to help you understand the diagnosis, cope with the emotional impact, and manage any necessary lifestyle changes.

Ongoing monitoring through regular medical appointments will be necessary to track the progress of the infection, the effectiveness of treatment, and any potential side effects or complications.

Key Figures

Globally, approximately 39 million people are living with HIV, while about 254 million have chronic Hepatitis B and nearly 50 million have chronic Hepatitis C.

In the UK, 106 890 people are living with HIV. Estimates suggest that 180 000 individuals have chronic Hepatitis B infection, with approximately 62 600 living with chronic Hepatitis C.

Together, chronic Hepatitis B and C contribute to 1.3 million deaths worldwide annually due to liver disease and cancer.

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.

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.

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.

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.

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.

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.

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.

fAQ

How is the Multiplex PCR test different from the antibodies test?
The Multiplex PCR test detects the presence of genetic HIV material, rather than antibodies. Multiplex testing locates the DNA copy of the HIV virus itself. This is usually present sooner than the antibodies that the body produces in response to an infection.
How accurate is the Multiplex PCR test in detecting HIV?
Recent research suggests that the Multiplex test is 98% accurate if taken 10 days after exposure.
Is the test painful?
Multiplex testing is done using a blood sample, so the test procedure is no different to other sexual health blood screenings. The blood test is quick and relatively painless; you may feel a slight scratch or pricking feeling when the needle is inserted.
How accurate is multiplex detection testing?
These tests are highly sensitive and specific, meaning they can reliably detect even small amounts of infection-causing organisms.
