An honest side-by-side comparison of the UK's three main private blood testing services covering biomarker coverage, collection method, turnaround time, reporting, pricing, and subscription models.
Thriva vs Medichecks vs TrueVitals — Which Blood Test Is Best in 2026?
Thriva tests up to 50 biomarkers via a shoulder collection device with subscription pricing from £30 per test. Medichecks tests up to 59 biomarkers with finger-prick collection as default and venous draw available for an additional fee, priced from £39 to £249. TrueVitals tests up to 110 biomarkers with professional venous blood draw included at 350+ UK clinics, a 60-page personalised AI report, and no subscription — from £159. Results in 48 hours.
All three are legitimate private blood testing companies operating in the UK. They serve slightly different markets and the right choice depends on what you are looking for. Here is an honest comparison.
Biomarker coverage. This is where the biggest difference lies. Thriva's most comprehensive option covers approximately 50 biomarkers built up over multiple subscription tests. Medichecks' Optimal Health panel covers 58-59 biomarkers. TrueVitals' Ultimate panel covers 110 biomarkers in a single test. That includes everything Thriva and Medichecks test plus a full hormone panel, cancer markers, immune markers, insulin resistance markers, cystatin C, lipoprotein(a), and a complete urinalysis. If you want the most thorough picture of your health from a single blood draw, TrueVitals tests nearly twice as many biomarkers as the next closest option.
Collection method. Thriva uses a Tasso+ shoulder collection device which is more comfortable than a traditional finger prick but still collects a relatively small sample. Medichecks defaults to finger-prick home kits with venous draw available at clinics for an additional £25-59. TrueVitals uses professional venous blood draw at over 350 clinics across the UK as standard, included in the price. Venous draw provides a larger, higher-quality sample which allows for more accurate results across a wider range of biomarkers. There is a reason hospitals never use finger-prick tests for comprehensive bloodwork.
Results and reporting. Thriva provides results on a dashboard with brief explanations and GP recommendations. Medichecks provides results with doctor-reviewed commentary. TrueVitals provides a 60-page personalised report generated by AI that includes a full executive summary connecting your symptoms to your biomarkers, colour-coded range bars showing both normal and optimal ranges, key health flags, targeted supplement recommendations with specific forms, doses, and timing, lifestyle recommendations based on your quiz data, and clinical follow-up guidance. This is the most significant differentiator. No other UK blood testing service produces anything comparable to this report.
Turnaround time. TrueVitals delivers results within 48 hours of your blood draw. Medichecks typically takes 3-5 working days. Thriva can take 2-15 working days depending on the test.
Pricing. Thriva starts from £30 per test on a subscription model but their comprehensive options cost considerably more when built up over multiple tests. Medichecks ranges from £39 to £249 depending on the panel. TrueVitals ranges from £159 for the Core panel (47 biomarkers) to £349 for the Ultimate panel (110 biomarkers). On a per-biomarker basis, TrueVitals' Ultimate panel costs £3.17 per biomarker. Medichecks' most comprehensive panel works out to approximately £4.29 per biomarker. Thriva varies by plan but is generally around £3.76 per biomarker. TrueVitals also offers Klarna for interest-free monthly payments.
Subscription model. Thriva is built around subscriptions. Medichecks and TrueVitals are both one-off purchases with no subscription required.
The verdict. If you want a basic check of a few markers at the lowest possible price, Thriva's subscription model may suit you. If you want a mid-range panel with doctor commentary, Medichecks is a solid option. If you want the most comprehensive blood test available in the UK with nearly twice the biomarker coverage, professional venous collection, the fastest turnaround, and a personalised 60-page report that tells you exactly what to do with your results, TrueVitals is the clear choice.
