What a private blood test actually involves, what it costs, what it checks, and how to choose the right one. A straightforward guide for anyone considering private testing for the first time.
A private blood test is a blood test you pay for directly, outside the NHS. You choose which markers to test, book at a time that suits you, and receive your results within days rather than weeks. No GP referral is needed.
The NHS provides blood tests when a doctor decides one is clinically necessary. That means the test is targeted at a specific concern and typically checks 10 to 20 markers. Private testing lets you take a proactive approach, checking 70 to 200+ biomarkers across every major health system in a single test, whether or not you have a specific concern.
The laboratory analysis is equally accurate. Both NHS and private tests use accredited UK laboratories. The difference is scope: how many markers are tested, how quickly you receive results, and how the results are reported to you.
Select the level of testing you want, from basic checks (~20 markers) to comprehensive panels (114-200+ markers). Most providers offer tiered options at different price points.
Depending on the provider, you either receive a home kit (finger-prick or shoulder device) or book a venous blood draw at a clinic or with a mobile phlebotomist who visits your home.
For venous collection, a trained phlebotomist draws blood from your arm. The process takes 5-10 minutes. Fasting for 8-12 hours before a morning draw gives the most consistent results.
Your sample is sent to an accredited UK laboratory for analysis. Most providers use CPA or UKAS-accredited labs. Results are typically ready in 1 to 5 working days.
Results are delivered via an online dashboard, app, PDF, or personalised report depending on the provider. Some include doctor review. Some offer AI-powered analysis.
Use your results to make informed decisions about diet, exercise, supplementation, or follow-up with your GP. Share your report with your doctor for the fullest picture.
The answer depends on the provider and panel you choose. Here are the main categories of biomarkers available through private testing in the UK.
Red cells, white cells, platelets, haemoglobin. The foundation of any blood test. Screens for anaemia, infection, and blood disorders.
ALT, AST, GGT, bilirubin, albumin, creatinine, eGFR, urea. Assesses how well these organs are filtering and processing.
Total cholesterol, LDL, HDL, triglycerides. Advanced panels add ApoB, Lp(a), and homocysteine for a far more accurate risk picture.
TSH at minimum. Better panels include Free T3, Free T4, and thyroid antibodies. This is where many basic tests fall short.
Testosterone, oestradiol, SHBG, cortisol, DHEA-S, LH, FSH, progesterone, prolactin. Essential for understanding energy, mood, fertility, and recovery.
Glucose, HbA1c, insulin, C-peptide, HOMA-IR. The deeper markers reveal insulin resistance years before diabetes becomes visible on standard tests.
Vitamin D, B12, folate, iron, ferritin, zinc, magnesium. Deficiencies are common and often behind symptoms like fatigue, brain fog, and poor recovery.
hs-CRP, immunoglobulins, complement proteins. Chronic low-grade inflammation is linked to cardiovascular disease, autoimmune conditions, and accelerated ageing.
Comprehensive panels also test tumour markers, autoimmune markers, urinalysis, and specialist markers like cystatin C and parathyroid hormone. See every biomarker TrueVitals tests.
Private blood test pricing in the UK varies widely depending on the number of biomarkers, collection method, and report quality.
| Level | Biomarkers | Typical Price | What You Get |
|---|---|---|---|
| Basic check | 10-20 | £50-£100 | Cholesterol, liver, kidney, thyroid (TSH only), testosterone. Finger-prick. Dashboard results. |
| Mid-range panel | 40-70 | £150-£250 | Adds hormones, vitamins, iron studies. May include venous option. Basic report or dashboard. |
| Comprehensive panel | 70-114 | £269-£349 | Full hormones, full thyroid, advanced cardiovascular, metabolic depth, tumour markers. Venous collection. Personalised report. |
| Maximum depth | 200+ | £799 | All of the above plus neurological, digestive, autoimmune, extended tumour markers, physical measurements. Specialist lab processing. |
Collection fees are typically £19-£39 for a clinic visit and £39-£59 for a home phlebotomist visit, depending on the provider. Some providers include collection in the panel price. Most offer interest-free payment options. See our full pricing breakdown.
Five things to consider before you buy.
More markers means more insight, but only if those markers cover different health systems. A panel of 50 markers across 4 systems tells you less than a panel of 50 across 10. Check which categories are included, not just the total number. What makes a test comprehensive →
Finger-prick kits are convenient but limited by sample volume and prone to haemolysis. Venous blood draws provide a larger, cleaner sample and support panels of 70+ markers. For comprehensive testing, venous collection is the standard. Why collection method matters →
Some providers deliver a dashboard showing whether markers are high, low, or normal. Others deliver a personalised report explaining what your results mean together and what to do about them. The report is what you are actually paying for. See how TrueVitals reports work →
Check whether a medical professional reviews your results before release. Some providers offer this as standard, some as an add-on, some not at all. A doctor review adds a layer of clinical oversight that a dashboard alone cannot provide.
Do not compare on headline price alone. A £150 test checking 30 markers costs £5.00 per biomarker. A £349 test checking 114 markers costs £3.06. The more comprehensive test is better value per marker and gives you a significantly fuller picture.

No. Private blood tests are available directly to anyone. You choose your panel, book your collection, and receive results without GP involvement. You can share results with your GP if you wish.
Yes. Reputable private providers use the same CPA or UKAS-accredited laboratories that NHS hospitals use. The analysis methodology and accuracy are equivalent. The difference is the scope of what is tested and how results are reported.
For the most consistent results, fast for 8 to 12 hours before a morning blood draw. Water is fine. Fasting particularly affects glucose, triglycerides, and insulin levels. If you cannot fast, your results are still clinically useful, but some markers may be less reliable. How to read your results.
Yes, and we recommend it for anything that needs clinical follow-up. A comprehensive private blood test gives your GP deeper data to work with than a standard NHS panel. Most GPs welcome this. Share your PDF report directly.
Annually is a strong baseline for most people. Every 6 months for athletes, people on HRT or TRT, and those monitoring chronic conditions. The first test establishes your baseline. Repeat tests show trends and confirm whether changes you have made are working.
