Best UK Private Blood Test Providers Compared (2026)
Search for a private blood test in the UK and you will find at least fifteen companies happy to take your order. They all send samples to accredited laboratories and all of them email you results within a few days. On paper they look identical. In practice, the price of the same test can double from one provider to the next, and the experience of getting your sample taken varies a lot more than people expect.
We track prices for 638 tests across 16 providers on our own database and update them daily, so the numbers below are current at the time of writing. This comparison was refreshed in late September 2026 to add Better2Know and MyHealthChecked and to reflect current prices.
How we compared them
Four things matter when you are choosing between providers, and we scored each one on all four using the same criteria as our methodology page. Price means the cost of a comparable single test, taken from our own database. Test range matters because some companies sell 75 different tests and others sell 5. Sample method covers the difference between a finger-prick kit at home, a clinic appointment and a visiting phlebotomist, which are three very different experiences. Turnaround is how long you wait from posting your sample to seeing results.

The providers in detail
Medichecks
Medichecks has been going since 2004 and it shows in the range: we track 75 tests from them, more than any other generalist. They are also the cheapest on single markers more often than not. Testosterone is £19, vitamin D, cholesterol, ferritin and kidney checks are all £39, and a thyroid function panel is £45. If you want a clinic blood draw rather than a finger-prick kit, they can arrange one for about £35, or a nurse visit to your home for around £59. Results usually land within 24 to 48 hours.
Better2Know
Better2Know is the biggest list on our database at 260 tests, and most of it is sexual health screening: individual STI tests from £35 up to comprehensive panels. They also carry a wellness range, and it is competitively priced. Cholesterol is £39, an inflammation (hs-CRP) check £39, and liver function £55. You can post a finger-prick kit, book a clinic appointment, or have a nurse visit your home, which gives them the widest choice of sample methods of anyone here. Results for most STI screens come back within a few days, and some same-day at clinics.
Forth
Forth is app-first. You order a home kit, post it back, and results appear in their app with health scores and trend lines, which makes it the natural pick if you plan to retest every few months and watch numbers move. Testosterone starts at £29 and a ferritin test at £39. Their range runs from simple single markers up to a TruCheck cancer screen, so the spread is wide. Turnaround is about two working days.
Goodbody Clinic
Goodbody operates 200+ clinic locations, and their 4.8 Trustpilot rating is the highest of the group we have verified. Prices sit in the middle: testosterone £49, HbA1c £49, and their range covers 47 tests on our database. If finger-prick kits put you off and you would rather a phlebotomist took a proper vial at a clinic, they are the value option for that.
Thriva
Thriva built its name on personalised insights and easy retesting, with a subscription option if you want results on a schedule rather than ordering one at a time. Their test list is shorter at 17, starting at £55.80 for an advanced iron profile. Results take 48 to 72 hours. They suit someone who wants interpretation hand-holding along with the numbers.
Numan
Numan started in men’s health and still leans that way, with 16 tests on our database from £40.60 for a cholesterol check. The unusual feature is a money-back guarantee if every marker in your test comes back normal, and everything is done by home kit. For women’s hormones or cancer screening you would need a different provider.
Bluecrest Wellness
Bluecrest does things the other way round: instead of home kits, they run health MOTs at 400+ venues across the UK, and their cheapest test on our database is £65 for an advanced diabetes check or a thyroid function test. Full screens run up to £339. If you want a proper face-to-face appointment and a broad panel of markers in one sitting, they are the obvious choice, with a 4.7 Trustpilot rating behind them.
Randox Health
Randox is the old hand here, founded in 1982, with their own laboratories and proprietary multi-marker technology. We track 5 tests from them, starting at £36 for a vitamin D test and £37 for thyroid function, and their clinic network covers 30+ locations. Their strength is bundled screens rather than cheap single markers.
MyHealthChecked
MyHealthChecked is the Boots own-brand partner, and it is the budget entry point on this list. Rapid finger-prick tests cost £8 for vitamin D or iron deficiency and £10 for bowel health or a stomach ulcer (H. pylori) check, with laboratory-processed kits alongside from £45. The catch is what a rapid test is: a screening hint you read yourself in minutes, not a full laboratory panel with a doctor’s review. Good for a quick steer, not for a baseline.
Lola Health
Lola is the premium option. Every test includes a qualified phlebotomist visiting your home to take a venous sample, so there is no kit to fumble with. The headline list starts at £10 to £15 for single-marker add-ons, but those must be added to a main blood test; a realistic standalone price is around £81 for a liver and kidney function panel. The company is new, founded in 2024, and the range is the widest for individual biomarkers, and the convenience is hard to beat if you dislike self-sampling.
Specialists worth knowing
The big generalists do not cover everything. Check4Cancer focuses on screening for specific cancers, with at-home bowel screening from £93. YorkTest has 40 years of history and is best known for food intolerance testing, though their standard tests are priced fairly too, at £41 for vitamin D, cholesterol or liver function. Vitall bundles nurse-led health checks with home testing from £59 for a thyroid function test, and Andro Prime is a new men’s hormone specialist with three kits from £99. BetterYou sells simple at-home kits from £29.99 for vitamin D, if you want one marker without a full panel.
What the cheapest tests cost right now
These are live prices from our database at the time of writing.
| Test | Cheapest provider | Price |
|---|---|---|
| Vitamin D (rapid test) | MyHealthChecked | £8 |
| Testosterone | Medichecks | £19 |
| Vitamin D (lab test) | BetterYou | £29.99 |
| Ferritin | Medichecks | £39 |
| Cholesterol | Medichecks | £39 |
| Liver function | Medichecks | £39 |
| Thyroid function | Randox Health | £37 |
| HbA1c (diabetes) | Forth | £46 |
For a laboratory-processed result with a doctor’s review, the first three rows read differently: MyHealthChecked’s £8 is a rapid test you interpret yourself, so for a proper lab test Medichecks at £39 is the floor.

Which one should you pick?
If price is the whole decision and you are fine with a finger-prick kit, Medichecks wins most single tests outright. If you want to track results over months or years, Forth’s app and Thriva’s subscriptions are built for exactly that. If you cannot face self-sampling, book Goodbody at a clinic, Bluecrest at one of their 400+ venues, or Lola if you would rather the nurse came to you. If you want everything checked in one appointment, Bluecrest’s screens or Randox’s bundles do that in a morning. If you need sexual health screening, Better2Know has the deepest list and the most sample options. And if the test is for a specific concern such as bowel cancer risk, a specialist like Check4Cancer will get you there faster than a general MOT.
I have used three of these myself over the past couple of years, and the honest answer is that the sample method matters more than most people expect. A kit that arrives with clear instructions and a prepaid envelope gets used. One that does not sits in a drawer until it expires.
What if your results come back abnormal?
Whichever provider you choose, an out-of-range result is the start of a conversation, not a diagnosis. Take the report to your GP, especially since every provider we track sends results reviewed by a doctor with notes on next steps. If a marker is slightly off, retesting with the same provider in three months gives you a cleaner trend than switching, because lab methods differ. And if something is flagged urgently, skip the retest and see a GP now.
