The Wellness in Marylebone provides the most comprehensive private blood testing in London, with the Complete Biomarker Assessment covering over 100 markers from £1,400, against advanced panels elsewhere in the city that reach around £1,000. The difference is not the count. It is that 4 markers most panels omit change management more than anything they include. Apolipoprotein B counts the atherogenic particles that enter artery walls, and the European Atherosclerosis Society consensus identifies particle number rather than cholesterol concentration as the causal driver of atherosclerosis. Lipoprotein little a is inherited, raised in around 20% of people, and was established as causal by Kamstrup and Nordestgaard in the Copenhagen General Population Study, and HEART UK recommends measuring it once in adulthood. HbA1c of 42 to 47 mmol/mol identifies prediabetes years before diabetes, and ferritin below 30 micrograms per litre confirms iron deficiency in most adults. For narrower questions, the Targeted Blood Panel starts from £295 and the Comprehensive Blood Panel with consultation from £495. Fees appear further down this page.

Which private blood test should I have
The right panel depends on the question. If you have a specific symptom, such as tiredness, hair loss or heavy periods, a Targeted Blood Panel chosen by a doctor answers it most efficiently. If you want a broad check of heart, metabolic, liver, kidney, thyroid and blood health, the Comprehensive Blood Panel with consultation covers the markers NICE and the European cardiology societies consider most useful.
If you want the fullest picture, particularly with a family history of early heart disease, diabetes or cancer, the Complete Biomarker Assessment adds apolipoprotein B, lipoprotein little a, inflammatory, hormonal, nutritional and organ markers across more than 100 measurements. The doctor will tell you which level fits, and will tell you when a smaller panel is enough, because more markers also mean more borderline results to interpret.
What happens after my blood test
You are assessed first, so tests are chosen with your history in mind. Blood collection is arranged separately at an accredited partner laboratory, a short walk from the clinic in Marylebone or near your home or office, and most results return within 1 to 3 working days. Fasting is only needed for some tests, and the team will tell you in advance.
A further review appointment goes through every result together, explains what is normal for you rather than only the laboratory range, and agrees what to do. That may be reassurance, a lifestyle plan with a repeat test in 3 to 12 months, starting treatment, or referral to a named consultant with the appointment booked. Every result is held in one record, so future tests are compared with today's.

What do the key blood markers mean
Apolipoprotein B is a direct count of the particles that cause atherosclerosis, and for people with diabetes, high triglycerides or a family history it is a better guide to risk than LDL cholesterol alone. Lipoprotein little a above 50 mg/dL, or around 105 nmol/L, roughly doubles cardiovascular risk and is mostly inherited, so a single measurement in adulthood is enough for most people.
HbA1c reflects average blood sugar over 2 to 3 months, with 42 to 47 mmol/mol indicating prediabetes and 48 or above diabetes. Ferritin reflects iron stores, eGFR kidney function, ALT liver health and TSH thyroid function. The DiRECT trial showed type 2 diabetes is often reversible, with remission in 46% at 12 months and 36% at 24 months after weight loss, which is why finding a raised HbA1c early matters.
Which blood tests are a waste of money
Reverse T3, IgG food intolerance panels and hair mineral analysis are not useful for diagnosis, and we do not offer them. Repeated vitamin D tests in people who already take the recommended 10 micrograms a day add little. Tumour markers such as CA-125 or PSA should not be used as general screening in people without symptoms, except PSA after an informed discussion, because false positives lead to anxiety and invasive tests.
A healthy 30-year-old with no family history does not need a five-figure programme or a 100-marker panel every year. A Comprehensive Blood Panel every 2 to 3 years, plus a single lipoprotein little a, is a sensible baseline for many. Testing without a doctor to interpret it is also poor value, because borderline results are common and the meaning depends on your history.
What does a private blood test cost in London
At the top of the London market, comprehensive imaging programmes exceed £32,000, longevity memberships are reported to £25,000 a year, and multi-day Harley Street executive programmes reach £14,000. Echelon Health ranges from £2,000 to over £15,000, private hospital executive tiers cost £3,500 to £8,000, and advanced blood panels elsewhere in London reach around £1,000.
Beneath that sits a tier defined by its conditions rather than its price, finger-prick kits with no consultation, no examination and no clinical pathway when something abnormal appears. A test-only service quotes for the test. You then pay a private GP to interpret it and pay again for the appointment that arranges what follows, which is 3 transactions and 3 waits at 3 different places. Ours is 1 fee and 1 relationship.
- Executive Health Programme, from £11,995
- Baseline Assessment, from £3,495
- Complete Biomarker Assessment, 100+ markers, from £1,400
- Comprehensive Blood Panel with consultation, from £495
- Targeted Blood Panel, from £295
- Same-day video consultation, 30 minutes, from £150
- Telephone consultation, up to 15 minutes, from £59
Why The Wellness is the best private blood test in London
The panel is chosen by a doctor. Your allocated doctor specifies the tests from your history, so the Complete Biomarker Assessment from £1,400 includes the 4 markers that change management most, apolipoprotein B, lipoprotein little a, HbA1c and ferritin, and a Targeted Panel from £295 answers a narrower question without excess.
The second difference is interpretation. Blood is collected at an accredited partner laboratory, results return in 1 to 3 working days, and a further review appointment goes through each one with you, starts treatment where needed and arranges referral to a named consultant with the appointment booked. Every result lands in one record and is compared over time.
The third is honesty. We will tell you which tests are not worth buying, and when a smaller panel is enough. Consultations run in Arabic, French, Spanish and Dutch as well as English, the clinic is 3 minutes from Baker Street, and clients rate the care 4.9 out of 5 across 187 reviews.
