UK Blood Test Companies
Compared 2026

The short answer: UK private blood tests split into three kinds. Home kits (Thriva, Medichecks by default, Forth, Numan) are cheap and convenient but capped at 20 to 59 markers by the sample. Clinic assessments (Bupa, Nuffield, Bluecrest, Randox) add a physical examination but test 30 to 100 blood markers for £400 to £1,200. Comprehensive venous panels test 70 to 230 markers with a phlebotomist's draw; the deepest and lowest per marker is TrueVitals Ultimate, 140 biomarkers for £349 plus £19, clinician-reviewed and guaranteed.

Cheapest trackingThriva: 40 to 50 markers from a shoulder device, £99 to £149 or about £30 a quarter.
Widest catalogueMedichecks: over 300 individual tests, regular sales, venous for £25 to £59 extra.
DeepestTrueVitals Signature: 230 markers through Randox Health, £799 including the draw.

Three kinds of test

Why the prices don't line up with the depth

Home kits: £39 to £250Thriva, Medichecks by default, Forth, Numan, Boots, Superdrug. You collect the sample yourself. Cheap and convenient, but a capillary sample caps the panel at about 50 markers and is unreliable for hormones, cortisol and insulin. Good for a few basics; not a screen.
Clinic assessments: £400 to £1,200Bupa, Nuffield, Bluecrest, Randox. You get a physical examination, ECG, blood pressure, body composition and a clinician on the day. The blood panel underneath is 30 to 100 markers. You are paying for the appointment, not the blood depth.
Comprehensive venous panels: £235 to £800TrueVitals, Lola Health, Randox's larger panels. A phlebotomist takes a venous sample and the panel runs 70 to 230 markers. This is where ApoB, Lp(a), fasting insulin, full thyroid, complete hormones and tumour markers live.
The sensible combinationMany people do a comprehensive venous panel every year for depth and a clinic assessment every two or three years for the physical checks. Neither replaces the other.

One-paragraph verdicts

TrueVitals. The most comprehensive: 140 or 230 markers, venous, written clinician-reviewed report, two guarantees, £2.63 per marker. Weaknesses: younger brand, no single tests, no finger-prick, appointments booked by phone after payment. Ultimate · all eight ranked.

Randox Health. The strongest laboratory and its own clinics, ~100 markers with physical measurements for £416, dashboard reporting, 5 to 10 days. Its £2,112 Signature Prestige programme is the closest thing to TrueVitals Signature with consultations included. Compared.

Lola Health. The best mid-tier: 70 markers from a phlebotomist's home visit or clinic with ApoB, full thyroid antibodies, complete hormones including cortisol and DHEA-S, full iron studies and a GMC-registered doctor's written review, £235 all in. No Lp(a), fasting insulin or HOMA-IR, cystatin C, tumour markers beyond total PSA, immune screen or follow-up consultation. Compared.

One Day Tests. Own UKAS lab, same or next-day results, 71 markers for £325, finger-prick by default. Compared.

Medichecks. The widest catalogue and the name most people know; largest panel ~59 markers, venous costs extra, results with comments. Best for single tests. Compared.

Forth. Built for people who train: custom panel builder, HealthCoach scoring, two-day turnaround, ~50 markers, finger-prick by default. Compared.

Thriva. The polished subscription app: 40 to 50 markers from a shoulder device, cheapest per marker, no venous option. Compared.

Bupa and Nuffield. Clinic assessments with ECG, body composition and a consultation; 30 to 40 blood markers for £1,065 to £1,199. Buy for the examination, not the blood depth. Bupa · Nuffield.

Bluecrest. Venue-based screening for the over-50s with a short blood panel, ECG and optional ultrasound. Compared.

Numan. A men's health platform whose ~20-marker finger-prick test leads to testosterone, hair-loss and weight-loss treatment. Compared.
