London W1G · Harley Street
Harley Street is an address, not an accreditation. The blood taken there goes to the same UKAS-accredited laboratories as blood taken anywhere else in the country, and the analysers do not know which postcode the tube came from. What the address buys you is a consultant's time and a good waiting room, and on Harley Street a private consultation alone runs from £200 to £400 before any test is ordered. If you want the consultation, it can be worth every penny. If you want the blood work, you can have it drawn on Harley Street itself, at a TrueVitals partner clinic in W1G, for £269 to £799 with a written report in 48 hours.
Two partner clinics in W1G, both minutes from Oxford Circus, Bond Street and Regent's Park. Venous draw £19. No GP referral, no consultation fee.

The short answer
A blood test on Harley Street is not more accurate than a blood test anywhere else; the laboratory does the analysis, and the good ones are UKAS-accredited wherever the sample was taken. What varies enormously is what you are charged, how many markers you get, and whether anyone explains them. TrueVitals draws blood at two partner clinics in W1G, tests 74 to 230 biomarkers including the ones most private profiles leave out, and sends a written report within 48 hours. You pay for the panel and the draw. There is no consultation fee, because there is no consultation.

Where the money goes
A Harley Street blood test bill usually has three parts: the consultant's time, the phlebotomy, and the laboratory analysis. The third part is the smallest and it is identical wherever you go, because the samples travel to the same handful of accredited labs. The first part is where the money is, and whether it is worth it depends entirely on what you need. A cardiologist reading your results alongside an echocardiogram, or an endocrinologist untangling a complicated thyroid picture, is worth a consultation fee and more. Someone ordering a standard profile because you asked for a check-up is not, and you will typically get twenty to forty markers for the privilege.
Worth the consultation
A specific diagnosed condition, an abnormal result that needs interpreting alongside imaging or examination, a second opinion, or anything requiring a prescription or a referral. A panel is not a substitute for a clinician who can examine you, and this page will not pretend otherwise.
Not worth the consultation
A comprehensive annual check, a baseline before or during treatment, tracking what you are changing, or finding out why you feel flat when the GP screen came back normal. That is a testing question, and paying £300 for someone to order it adds nothing to the result.

Honest comparison
If you have chest pain, a lump, unexplained weight loss, bleeding, or any symptom that needs examining rather than measuring, see a doctor and do not spend the money on a panel first. If you have a diagnosed condition under specialist care, your consultant should be directing the testing. And if a result here comes back abnormal, the next step is often exactly the Harley Street appointment this page has been comparing against, except you will walk in with 114 markers and a written interpretation instead of a hunch, which tends to make the conversation shorter and more productive. That is the honest position: the two things are complements, and the mistake is paying specialist prices for a screening test you could have had for a fraction of it.
FAQs
It depends whether a consultation is required. A private consultation on Harley Street typically runs £200 to £400, with the blood profile on top, so an all-in cost of £400 to over £1,000 is common. A TrueVitals panel drawn at a W1G clinic is £269, £349 or £799 plus a £19 draw, with no consultation fee.
No. Accuracy comes from the sample and the laboratory, not the address. A venous sample analysed at a UKAS-accredited lab gives the same result wherever it was taken. What differs is how many markers are measured and how well they are explained.
Yes. TrueVitals draws at two partner clinics in W1G and no referral or consultation is needed. You choose the panel, book the appointment, and receive a written report within 48 hours of the lab receiving your sample.
Early morning slots are available, and they are the right choice anyway: cortisol must be drawn between about 8 and 9am to mean anything, and fasting insulin and lipids need an overnight fast. If getting to W1G is the problem, a phlebotomist can come to your home or office for £39.
Most standard private profiles cover 20 to 40 markers: lipids, liver, kidney, thyroid, blood count and a few vitamins. They usually omit ApoB and Lp(a), which predict cardiovascular risk better than LDL, fasting insulin and HOMA-IR, which show insulin resistance a decade before HbA1c moves, cystatin C for accurate kidney function, and a full hormone profile.
Many people put an executive health check through the business and you will receive a receipt suitable for that. Executive health check.
Advanced and Ultimate reports arrive within 48 hours of the laboratory receiving your sample, usually the same day as your draw. Signature takes around 12 working days given the depth of testing.
Drawn on Harley Street, analysed at a UKAS-accredited laboratory, and explained in a written report within 48 hours. 114 biomarkers for £349, or 230 for £799.
