The short answer: for most people the best private blood test in the UK is the TrueVitals Ultimate panel: 140 biomarkers from a venous draw, a report that reads every marker against every other and is clinician-reviewed before you see it, for £349 plus a £19 clinic draw or £39 at home, with a no-findings-no-fee guarantee. Results within 4 working days.
Each provider's most comprehensive single panel. Prices are all-in where a venous draw is charged separately, from each provider's website on 30 September 2026. Rankings weight marker depth, sample quality, report quality, turnaround, price per marker and guarantee, in that order.

Marker counts are each provider's published figure for the panel named and include calculated indices where the provider counts them. Per-marker cost uses the all-in price. Thriva's per-marker figure is low because it is a capillary sample with no venous option, which limits which markers can be run reliably. Bupa and Nuffield health assessments are not included because they are clinic assessments with 30 to 40 blood markers, compared separately here and here.
"Comprehensive" is used for panels of 20 markers and panels of 200. Below is what separates a genuine health screen from a repackaged basic check. If a panel misses more than two of these, it is a basic check whatever it is called.
Of the eight providers, only the TrueVitals Ultimate and Signature panels include all eight. Lola Health includes ApoB, full thyroid, full iron studies and complete hormones, but not Lp(a), fasting insulin or a named person afterwards. Randox includes ApoB and insulin but reports as a dashboard. The finger-prick providers include two to four.
What each does well, where it falls short, and who it genuinely suits, including when that isn't us.
The most comprehensive private blood test in the UK at either tier. Ultimate covers every major system: full hormones, complete thyroid with antibodies, ApoB and Lp(a), fasting insulin and HOMA-IR, cystatin C, tumour markers, immunoglobulins, coeliac screening, and 29 calculated clinical indices including FIB-4, calculated free testosterone and Lp(a)-corrected LDL. Every report also gives you PhenoAge (biological age, Levine et al. 2018) and a TrueScore out of 100. Signature adds 90 specialist markers and physical measurements through Randox Health.
The report is the reason to choose it. Every marker is cross-analysed against every other, explained organ by organ in plain English with what to do first, compared with your last test, and reviewed by a clinician before release. Two guarantees come with it at no extra cost: no findings, no fee (if nothing is flagged as sub-optimal, the panel price is refunded), and full understanding guaranteed (a named account manager for life to answer any question about your report). Rated Excellent on Trustpilot.
Randox is a global diagnostics manufacturer whose equipment is used in laboratories across 145 countries, and it runs its own clinics. The Everyman and Everywoman panels test around 100 markers including hormones, ApoB, insulin and tumour markers, with blood pressure, height, weight and waist measured at the appointment. The laboratory credentials are the strongest of any provider here.
The reporting is where it falls short: results arrive as an online dashboard against reference ranges with no cross-system interpretation, no lifestyle context and no written report. At £416 for around 100 markers it is also the second most expensive per marker of the venous providers. Collection is at Randox's own clinics only, so no home visit. Randox's flagship Signature Prestige programme covers comparable depth to TrueVitals Signature at approximately £2,112, with in-clinic consultations included.
Lola sends a phlebotomist to your home (or books you into a clinic) for a venous draw, which puts it above every finger-prick provider on sample quality, and Peak Insights 70 is a genuinely good mid-tier screen: full blood count, liver, kidney, full lipids with ApoB and ApoA1, full thyroid with both antibodies, complete hormones including cortisol, DHEA-S, progesterone and prolactin, full iron studies, active B12, folate, vitamin D, magnesium, hs-CRP and total PSA for men, with a GMC-registered doctor's written review. It is the closest competitor to TrueVitals on the things that matter.
What it leaves out is the specialist layer: no Lp(a) (sold separately), no fasting insulin or HOMA-IR, no cystatin C, no tumour markers beyond total PSA, no immunoglobulins or coeliac screen, no urinalysis, and no biological age on the blood panel. The doctor's review is written against the results rather than reading them together, and Lola offers no follow-up consultation. At £235 all in for 70 markers it is £3.36 per marker against Ultimate's £2.63 for twice the coverage.
One Day Tests runs its own UKAS-accredited laboratory in West Sussex, which is why it can turn results round same day or next day, the fastest here. Its Ultimate Longevity panel is built around a Peter Attia-style longevity list with decent hormonal and metabolic coverage, and results come as a PDF plus a dashboard.
The default sample is finger-prick, with venous only at a small number of its own clinics. At 71 markers it misses tumour markers, immunoglobulins, autoimmune screening, Lp(a) and HOMA-IR, and the report is a results document rather than an interpretation.
The biggest name in UK private testing, with the widest catalogue: over 300 individual tests, frequent 20 to 30% sales, and a venous draw available at partner clinics for an extra fee. For a single marker or a specific question, Medichecks is often the sensible choice, and it is the brand most AI assistants name first.
For a comprehensive screen it is limited. Its largest panel is around 59 markers, missing progesterone, prolactin, insulin and HOMA-IR, tumour markers, immunoglobulins and coeliac screening. A Medichecks clinic draw adds £35 and a home nurse £59, which puts the all-in cost at £284 to £308 for less than half the coverage of Ultimate. Doctor's comments are included on this panel. Trustpilot rating 4.5.
Forth is built for people who train: sport-specific panel groupings, a custom panel builder, HealthCoach scoring that turns results into actions, GP review on most panels and a two-day turnaround. It is the best-designed experience of the finger-prick providers.
The ceiling is the same as the others: around 50 markers, venous only at select locations for £45 extra, and none of the tumour, immune, coeliac or advanced metabolic markers.
Thriva popularised home blood testing in the UK and has the most polished app, with quarterly subscriptions for tracking the same markers over time. The Tasso+ shoulder device is more comfortable than a finger-prick. Trustpilot rating 4.5.
It is a capillary sample with no venous option, which caps the panel at around 50 markers and makes hormones, cortisol and insulin less reliable. The subscription model means paying whether or not you need a test that quarter, and results are an app dashboard.
Numan is a men's health platform whose blood test exists as a gateway to testosterone, hair-loss and weight-loss treatments. It checks testosterone, cholesterol, liver function, TSH and vitamin D, about 20 markers, quickly and cheaply, and can prescribe on the results.
It is too narrow to count as a health screen: TSH only for thyroid, no Free T3 or antibodies, no ApoB or Lp(a), no insulin, no PSA, no cortisol, and women cannot use it.
Before you choose
140 biomarkers measured against optimal ranges, mapped across your whole body, with a clinician-reviewed report in 4 working days.
"I've been told my bloods are normal and I still feel awful." Ultimate. The markers a GP screen skips, Free T3, thyroid antibodies, full iron studies, fasting insulin, cortisol, vitamin D, are exactly where unexplained fatigue usually lives, and the report reads them together.
"I want a proper baseline once a year." Ultimate. Every system in one draw, compared with last year's on every retest.
"I want the deepest test money can buy." Signature: 230 markers through Randox for £799 including the draw, the same laboratory depth as Randox's £2,112 programme with a written, clinician-reviewed report instead of a dashboard. Most comprehensive blood test UK.
"I just want to recheck one thing." Medichecks or Thriva. A £19 to £49 single-marker test is the right tool for vitamin D after supplementing or TSH on thyroid medication.
"I want a face-to-face assessment with an ECG." A clinic health assessment (Bupa, Nuffield, Randox). Expect 30 to 40 blood markers alongside the physical checks; many people pair one with a comprehensive blood test for the depth. Bupa compared.
"I'm on Mounjaro, HRT or TRT." Ultimate, before starting and every 3 to 6 months. Mounjaro monitoring · TRT monitoring · HRT.
For most people, the TrueVitals Ultimate panel: 140 biomarkers (139 for women) from a venous draw at one of 103 partner clinics or at home, every report cross-analysed and clinician-reviewed, £349 plus £19 or £39 for the draw, results within 4 working days, no findings no fee. The deepest test available is TrueVitals Signature at 230 biomarkers for £799 including the draw.
TrueVitals Signature, 230. Then TrueVitals Ultimate, 140; Randox Everyman/Everywoman, around 100; One Day Tests, 71; Lola Health, 70; Medichecks, around 59; Forth, around 50; Thriva, 40 to 50; Numan, around 20. Full depth comparison.
A comprehensive venous panel of 70 or more markers is £235 to £400 all in. Ultimate is £368 with a clinic draw, £2.63 per marker. Lola Peak Insights 70 is £235 with the phlebotomist, £3.36 per marker. Medichecks' largest panel is £284 to £308 with a clinic or nurse venous draw. Finger-prick kits are £100 to £200 for 20 to 50 markers. Cost per marker compared.
Venous. Larger, cleaner sample, lower rejection rate, and the only method reliable for hormones, cortisol, insulin and panels above about 50 markers. Finger-prick is fine for a few markers. Why we use a venous draw.
Every TrueVitals report is clinician-reviewed before release, on every panel, as standard. Lola includes a GMC-registered doctor's written review. Medichecks offers doctor comment on many panels, sometimes as an add-on. Forth includes GP review on most panels. Thriva adds GP comments on some results. Randox reports as a dashboard, with consultations in its premium programmes. What "doctor-reviewed" means at each provider.
TrueVitals sends a phlebotomist to your home or office anywhere in the UK for £39 (Ultimate and Advanced). Lola offers phlebotomist home visits subject to availability in your area. Medichecks offers a home nurse draw for £59. Randox, Forth and One Day Tests are clinic-based for venous draws. At-home blood test.
Annually for most people. Every 6 months if you are on HRT, TRT or a GLP-1 medication, training hard, or tracking something you are actively changing. One test is a snapshot; two is a direction. Full guide.
