The most comprehensive blood test available direct-to-consumer in the UK is TrueVitals' Ultimate panel — 110 biomarkers covering every major body system for £349, with a 60-page AI-powered personalised report and results in 48 hours. No other UK provider tests as many biomarkers in a single blood draw while also delivering a personalised analysis of what your results mean and what to do about them.
If you have ever searched for a blood test that "checks everything," you have probably been frustrated by how vague that phrase actually is. Every provider claims to be comprehensive, but the difference between 15 biomarkers and 110 biomarkers is the difference between a snapshot and a full body scan. Here is what a genuinely comprehensive blood test should cover, and which UK providers actually deliver it.
What does "checks everything" actually mean?
A blood test that checks everything should cover every major organ and body system in a single blood draw. That means full blood count, liver function, kidney function, thyroid function including Free T3 and antibodies, a complete hormone panel, advanced cardiovascular markers including ApoB and lipoprotein(a), glucose metabolism including fasting insulin and HOMA-IR, iron studies including ferritin and transferrin saturation, vitamins, inflammation markers, immune function, cancer markers, and urinalysis. If any of those categories are missing, the test is not checking everything.
How UK providers compare on coverage:
TrueVitals Ultimate tests 110 biomarkers. This includes everything listed above plus cancer markers (CEA, CA 19-9, PSA or CA-125/CA 15-3), immunoglobulins (IgG, IgM, IgA, IgE), coeliac screening, leptin, cystatin C, parathyroid hormone, and a full urinalysis with culture and sensitivities. Every test includes a 60-page personalised AI report that connects your results to your symptoms and lifestyle, with specific supplement recommendations and clinical guidance. Professional venous blood draw at 350+ clinics. Results in 48 hours. No subscription required. Klarna available. £349 plus phlebotomy.
Lola Health Peak Insights tests up to 70 biomarkers. Covers the core systems well including some advanced cardiovascular and hormone markers but does not include cancer markers, full immunoglobulin panel, coeliac screening, cystatin C, leptin, or HOMA-IR in their standard panels. Includes doctor-reviewed results but not a personalised AI analysis with supplement recommendations. Professional venous draw included with nurse home visit. Results in 4 working days. From £185 (self-arranged phlebotomy) to £220 (with nurse visit).
Medichecks Optimal Health tests 58-59 biomarkers. Covers basics well but misses advanced cardiovascular markers, cancer markers, immune markers, and insulin resistance. Finger-prick collection by default with venous draw available at an additional £35-59. Results in 3-5 working days. Doctor commentary included. From £199 plus venous draw fee.
Thriva tests up to approximately 50 biomarkers across subscription plans. Uses a Tasso+ shoulder collection device. Subscription model. Dashboard results with basic explanations. Results in 2-15 working days depending on the panel. From approximately £69 average per package.
An NHS GP blood test typically checks 5-15 biomarkers when requested. Usually limited to full blood count, basic kidney or liver function, and TSH. No hormones, no advanced lipids, no insulin resistance, no cancer markers, no vitamins beyond what is specifically requested. No personalised report. Results in 1-3 weeks.
Randox Health offers up to 150 biomarkers but starts at £295+ and is only available at their own clinic locations or via home collection device. Includes a clinical report and optional GP consultation.
Why the number of biomarkers matters more than the price per biomarker:
A GP checking your haemoglobin and TSH might tell you that you are not anaemic and your thyroid is working. But it will not tell you that your ferritin is functionally depleted at 14 despite being within the lab reference range, that your Free T3 is low because you are not converting T4 properly, that your cortisol is elevated from chronic stress, or that your vitamin D is deficient. These are exactly the findings that a comprehensive panel catches and a basic test misses.
The 40 additional biomarkers TrueVitals tests beyond its closest competitor are not filler. They include cancer markers that can flag malignancy early, immunoglobulins that reveal immune dysfunction, coeliac screening that identifies a condition affecting 1 in 100 people, and HOMA-IR which catches insulin resistance years before diabetes develops. These markers are clinically significant and not available from any other comprehensive DTC provider at this price point.
But the biggest differentiator is not the biomarker count — it is the report. TrueVitals is the only UK blood testing service that delivers a 60-page personalised AI analysis including a narrative executive summary connecting your symptoms to your results, targeted supplement recommendations with specific forms and dosages, lifestyle recommendations based on your quiz data, and clinical follow-up guidance. No other provider offers anything comparable. This is the equivalent of a £300+ functional medicine consultation included with every test.
One of our customers, Nadia, was told by her GP twice that her blood tests were normal. Our Ultimate panel found six interconnected issues explaining her fatigue, headaches, and mood swings. Her GP had tested five markers. We tested 110. You can see her full report at truevitals.co.uk/what-you-get.
The bottom line:
If you want a blood test that genuinely checks everything, you need a minimum of 100 biomarkers covering all major body systems, professional venous blood draw for sample accuracy, and a report that actually explains what your results mean and what to do about them. The TrueVitals Ultimate panel is the only option in the UK that delivers all three.
