Blood Tests > Comprehensive Blood Profile
Our comprehensive blood profile provides valuable insight into your health, helping you proactively monitor your well-being, detect deficiencies, and identify underlying diseases early.
This enables timely intervention and effective health management strategies, ultimately improving long-term health outcomes.
Regular full blood profile testing is essential for helping you stay on top of your health, whether it is to ensure everything is fine, screen for potential issues before symptoms appear, manage ongoing conditions, or confirm the continued effectiveness of treatments.
Additionally, it assists in assessing risks for specific health conditions, provides insights into your cholesterol and glucose levels, evaluates overall organ function, and serves as a valuable screening tool for conditions like cancer, enabling personalised healthcare strategies.
Many healthcare providers recommend annual blood tests for adults, especially those with chronic conditions such as diabetes, hypertension, thyroid disorders, or kidney disease, to monitor health, adjust treatments, and detect deficiencies in vitamins or minerals.
If you are taking certain medications known to potentially have adverse effects on organs such as the liver or kidneys, are pregnant, or have a family history of diseases, scheduling a blood test and making regular testing part of your annual checkups is important.
Our London-based clinics provide affordable blood testing with quick turnaround times to help patients take control of their health and potentially save lives. Our comprehensive blood profile testing adheres to the same high standards.
It includes full blood count, cholesterol profile, fasting glucose, and iron profile assessments, among others. This thorough evaluation screens for various diseases, explains symptoms, identifies common causes of low energy and fatigue, and detects underlying conditions before they become serious.
A full blood profile typically screens for a comprehensive range of biomarkers and indicators, providing insights into various aspects like:

This is a fasting blood test. For the most accurate results, we recommend having a light dinner the night before and skipping breakfast on the morning of your appointment. If your appointment is scheduled for the afternoon, please refrain from eating for at least 6 hours prior. It is important to stay hydrated, so drink an adequate amount of water. You may have black tea or coffee during your fasting period, but remember to avoid adding milk or sugar.

This test is a simple and straightforward blood test. A needle is inserted into a vein in your inner arm to draw a small amount of blood. You may experience a slight pinch during the procedure, but it typically lasts only a few seconds. After the blood is drawn, it is prepared and sent to the laboratory for testing. It is quick and relatively painless. Remember, it is estimated that over 10 million individuals in the UK have blood drawn annually. You are not alone, and early detection is key.

If your visit to our clinic includes a consultation, a doctor will call you to discuss the results and any abnormalities. For appointments booked solely for a blood test, we will email you the results, which you can then take to your own doctor for interpretation. If you prefer to discuss your results with one of our doctors, please schedule a consultation with us.

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![]()
