Advanced and Longevity Blood Tests in London

Aug 26

Written By Rhouda Elalfy

A blood panel is only as good as the markers it measures and the doctor who reads it, which is why The Wellness builds testing around your question rather than a generic list. From a single targeted check to a full picture of every system, our panels draw on more than a hundred and sixty biomarkers from accredited, gold-standard laboratories, and a physician reads the results in the context of your history and turns them into a plan you can act on. Most panels drawn before midday come back the same day, and no GP referral is needed. At The Wellness in London, advanced and longevity blood testing runs across three clear packages and a bespoke option, from £350, each read by an expert GMC-registered doctor. Fees appear further down this page.

Reviewed by the medical team at The Wellness. Last updated August 2026.

Request a biomarker panel on WhatsApp or email team@thewellnesslondon.com or call 020 3951 3429.

The three packages, and what each is for

The packages step up in depth, so you can start with a baseline or go straight to the full picture. Core Wellness, at £350, covers more than thirty biomarkers and gives you an elevated baseline, including full blood count, liver and kidney function, the metabolic and cardiovascular markers such as cholesterol and HbA1c, the inflammation marker high-sensitivity CRP, and the essentials of thyroid, ferritin and vitamin D. Advanced Health, at £650, covers more than fifty biomarkers and looks more closely at the systems that drive energy and general fitness, adding a full thyroid profile with free T3 and T4, complete iron studies, fasting glucose and insulin, sex-specific hormones and cortisol, and additional nutrients including B12, folate and magnesium, with a doctor consultation included. Longevity+, at £1,395, is the most comprehensive, spanning more than a hundred biomarkers that shape your current and future health, and it is built for people who want to understand and act on the whole of their biology.

What the Longevity+ panel actually measures

The value of a longevity panel is in the markers that routine testing leaves out, and Longevity+ is built around them. On the cardiovascular side it measures ApoB, which counts the actual number of artery-clogging particles rather than estimating the cholesterol they carry, alongside Lp(a), a genetically set risk factor worth measuring once in your life, plus ApoA1 and homocysteine. It goes into metabolic and inflammation detail, maps complete nutrient and mineral status including the omega-3 index, zinc, copper, selenium, vitamins A and E, iodine and active B12, gives a full hormonal profile for your biology, and assesses precision organ health with markers such as cystatin C, calcium, phosphate and liver fibrosis. An in-depth consultation with an expert physician reads all of it together, which is what turns a hundred numbers into a clear direction.

Book a longevity blood panel on WhatsApp or email team@thewellnesslondon.com.

Why a doctor, not just a portal

A list of numbers with reference ranges is not medicine. What changes anything is a physician who knows which markers matter, how they interact, and what to do about them, and who reads your results against your history rather than a population average. Every panel here includes that interpretation, with a doctor explaining what is strong and what needs attention, and giving you a personal wellness action plan. Because The Wellness is a full clinic, anything a result calls for is acted on by the same team, and your biomarkers are tracked over time through our technology, so each future result is read against your own baseline and you can watch the numbers move.

What advanced and longevity blood testing costs in London

Private longevity panels in London vary widely, from home-collection kits that post you numbers without a doctor to premium biological-age panels running well into four figures. The useful distinction is not the length of the list but whether a physician ranks and interprets it and whether the result becomes a plan.

At The Wellness the doctor and the interpretation are the product, results come back same-day for most panels drawn before midday, and no referral is needed. All figures are from prices.

Core Wellness, 30+ biomarkers, an elevated baseline, £350.
Advanced Health, 50+ biomarkers, a closer look at energy and fitness, consultation included, £650.
Longevity+, 100+ biomarkers, the most comprehensive picture with an in-depth physician consultation, £1,395.
Bespoke panel built from more than 160 biomarkers, priced at consultation.

Walk-in or by appointment, with home blood tests available across London including Chelsea, Kensington, Mayfair, Knightsbridge, Marylebone, Canary Wharf and the City. Samples are processed by The Doctors Laboratory, a UKAS-accredited, ISO 15189 laboratory.

Why The Wellness is the right clinic for this

Because the clinic is built around the one thing that makes a blood panel worth having, which is a doctor who knows which markers matter and what to do with them. The panels are read by expert GMC-registered physicians who put ApoB, Lp(a), insulin and the metabolic markers first, results are back the same day for most panels drawn before midday, and every package turns into a personal action plan rather than a spreadsheet. Because it is a full clinic, anything a panel uncovers flows straight into the right care through the same team, and your results are tracked over time so your health becomes legible rather than a series of one-off snapshots. Expert interpretation, gold-standard labs, genuine speed and continuity are what make it the clinic to use.

Request your panel on WhatsApp or call 020 3951 3429.

Frequently asked questions

What is the difference between the Core Wellness, Advanced Health and Longevity+ panels

Core Wellness covers more than thirty biomarkers as an elevated baseline for £350. Advanced Health covers more than fifty, adding full thyroid, iron studies, fasting insulin, hormones and cortisol with a consultation, for £650. Longevity+ covers more than a hundred, including ApoB, Lp(a) and full nutrient and organ-health detail with an in-depth physician consultation, for £1,395.

Can I get same-day blood test results in London

Yes. Results are available the same day for most panels drawn before midday, delivered through the secure patient portal and reviewed by a GMC-registered doctor. The most comprehensive panels may take twenty-four to forty-eight hours.

Do I need a GP referral for an advanced blood test

No. You can book directly without a referral, and a physician reviews your history, agrees the right panel and interprets the results with you.

What is ApoB and why is it on the longevity panel

ApoB counts the actual number of artery-clogging particles in your blood rather than estimating the cholesterol they carry, which makes it one of the most accurate single markers of cardiovascular risk and one an ordinary cholesterol reading can hide. It is included in the Longevity+ panel.

Can I have my blood taken at home

Yes. A trained phlebotomist can visit your home or office across London, including Chelsea, Kensington, Mayfair, Knightsbridge, Marylebone, Canary Wharf and the City.

The Wellness is a doctor-led private clinic in London. All doctors are GMC-registered and samples are processed by The Doctors Laboratory, a UKAS-accredited laboratory. This article is general information and not a substitute for medical advice about your own health.
