Sexual Health > STI Blood Test Screening
This blood test comprehensively screens for a range of sexually transmitted diseases (STDs) that can be detected in the bloodstream.
Specifically, it tests for HIV (Human Immunodeficiency Virus), which can lead to AIDS if untreated. Additionally, it checks for Hepatitis B and Hepatitis C, both of which are viral infections that affect the liver and can cause serious liver damage over time.
Finally, the test also screens for Syphilis, a bacterial infection that can cause serious long-term complications if not properly treated.
Engaging in unprotected sexual contact increases the risk of contracting sexually transmitted diseases (STDs), particularly those transmitted through blood. Many of these infections often do not exhibit symptoms, making it difficult to know your sexual health status without testing.
Undergoing STD testing is a quick and straightforward process that provides peace of mind, as most blood-transmitted diseases can be effectively managed or even treated if detected early.
Our STD Blood Test Screening package specifically targets the four primary sexually transmitted infections detectable through blood tests, namely HIV, Hepatitis B, Hepatitis C, and Syphilis.
These blood-transmitted infections can spread rapidly, often without any symptoms, and can lead to serious long-term health issues, including liver damage and other complications.
If you have had unprotected sex or are starting a new relationship, it is strongly recommended to get an STD Blood Test Screening. Our clinics offer years of experience, same-day appointments, and transparent pricing to help you recover sooner and put your mind at ease.
Curable blood-transmitted STDs include syphilis (treatment: antibiotics, typically penicillin).
Manageable blood-transmitted STDs include HIV/AIDS (treatment: antiretroviral therapy (ART) to manage and control the virus), Hepatitis B (treatment: antiviral medications; a vaccine is available for prevention), Hepatitis C (treatment: antiviral medications, such as direct-acting antivirals), and herpes simplex virus (treatment: antiviral medications, such as acyclovir or valacyclovir, to manage outbreaks and reduce transmission).
Many STDs can remain asymptomatic for long periods; therefore, early detection through blood screening is vital as it enables timely treatment, reduces the risk of long-term health issues, and prevents the spread of these infections.
Regular blood-related STD screenings are a key part of sexual health and well-being, especially for individuals with multiple sexual partners or those in high-risk groups.
Anyone who has engaged in activities that could potentially transmit sexually transmitted diseases through blood should consider getting tested. This includes:
Our London-based doctors are available to offer expert guidance on your test results. If you test positive for HIV, Hepatitis B, Hepatitis C, or Syphilis, it is essential to take the following steps promptly:
Use our online booking engine or book your appointment by giving us a call.
On the online booking engine select the “appointment type” you need.
You will be seen by one of our friendly doctors or trained clinicians.

There is no specific preparation required for this blood test. However, try to keep yourself hydrated by drinking an adequate amount of water. This helps facilitate the blood drawing process, making it easier for the healthcare provider to obtain a sample.

This test is a straightforward procedure involving a simple blood draw. Typically, a healthcare professional inserts a needle into a vein in your inner arm to extract a small amount of blood. During the process, you may experience a slight pinching sensation, but it is brief.

During your consultation, you will have the opportunity to discuss and decide how you would prefer to receive your test results. Options include receiving a phone call from the doctor, having the results sent via email, or calling the healthcare provider yourself to inquire. E

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![]()
