Medichecks vs Thriva: Which UK Blood Test Should You Choose? (2026)

1. Medichecks vs Thriva at a glance

Both prices and panels change. These figures were checked in June 2026, and the popular mid-range Medichecks panels sit between £79 and £139.

2. Where Medichecks wins

Breadth. No UK home-testing provider offers a wider menu. If you want one specific marker, an obscure hormone, or the 59-marker Optimal Health panel, Medichecks almost certainly sells it. The entry point is low too. A three-marker thyroid test costs £29, which makes it one of the cheapest ways in the UK to check a single system.

The doctor commentary. Every Medichecks report arrives as a PDF with written commentary from a doctor. That matters more than it sounds. A page of numbers with reference ranges can be genuinely alarming when one value sits slightly outside range, and a few sentences of context from someone qualified is often the difference between a sensible next step and a 2am search spiral.

Flexibility on sample method. Medichecks offers both finger-prick kits and venous draws at partner clinics. Larger panels need more blood than a finger-prick can reliably collect, so if you want all 59 markers in one go, the venous option exists. Thriva does not offer it.

The trade-off. The catalogue is the weakness as well as the strength. Hundreds of options means you are the one doing the choosing, and unless you already know which markers matter for your situation, it is easy to buy either too narrow or too broad. You also decide your own retest schedule. Nobody chases you.

3. Where Thriva wins

Speed. Thriva advertises results in as little as 48 hours from the lab receiving your sample. For people who hate waiting, that is a real advantage over providers where turnaround stretches across a week.

The app. Thriva is built app-first. Results land as a dashboard rather than a document, and the design assumption is that you will test again. Trends over time are the product. If you tested vitamin D in January, the app shows you what happened by April, which is something a folder of PDFs never does well.

The cadence. The subscription model retests you every three to six months without you having to remember. For anyone actively working on something measurable, say correcting a deficiency or watching cholesterol respond to a diet change, that rhythm does the discipline for you. Thriva also sells its own vitamin range, so the loop from result to supplement sits inside one app.

The trade-off.Depth. Thriva's panels are smaller than Medichecks' biggest, and one-off pricing from around £49 buys fewer markers than £49 might suggest. The product makes most sense if you commit to the subscription, and a subscription is exactly what some people do not want from a blood test. Cancelling is on you to remember.

4. The verdict, by use case

Choose Medichecks if you know what you want to test, you value a doctor's written take on your numbers, or you want the broadest single snapshot available from a UK home-testing provider. It suits the person who treats testing as an occasional deep audit rather than a habit. See our full Medichecks comparison for the panel-by-panel detail.

Choose Thriva if you want speed, you live in apps rather than PDFs, and the thing you care about is the trend line, not the snapshot. It suits the person fixing something specific over six to twelve months who wants the retest handled automatically. Our Thriva comparison goes deeper on the subscription maths.

Neither is a bad choice. Both use accredited labs. The real risk is not picking the wrong provider. It is paying for data you never act on, which brings us to the part of this comparison most guides skip.

5. The question neither answers: what do I do next?

Here is the honest pattern. Most people order a blood test, get the results, feel briefly informed, and change nothing. The catalogue model hands you breadth and the tracker model hands you trends, but both still leave the central decision with you: which of these numbers matters, and what specifically should I do about it?

That gap is where Helvy sits. We are neither a catalogue nor a tracker. There are five panels, priced £99 to £159, each curated around a goal (energy, hormones, heart, metabolic health) rather than a marker count, so the choosing is already done. A qualified clinician reviews every result. Results arrive as Your Read, a plain-English report scored against optimal ranges rather than just the wide “normal” bands, and it ends with a supplement plan built from what your blood actually showed. Not a quiz. Not a guess.

If you enjoy choosing markers, Medichecks will serve you well. If you enjoy watching graphs, Thriva will. If what you want is the decision made for you and a clear what-to-do-next, that is the thing we built.
