Private blood testing in the UK is now widely accessible — home finger-prick kits start at £25 with results in 1–3 working days. Venous draws at a clinic or at home cost £39–250+ depending on the panel. No GP referral is required. All reputable providers use UKAS-accredited laboratories.
How private blood tests work
Two main methods:
-
Home finger-prick kits — a kit is posted to your home. You prick your finger, collect a small blood sample, and post it back in a prepaid envelope. Results arrive online within 1–3 working days. Cost: £25–150.
-
Venous blood draw — a phlebotomist draws blood from your arm at a clinic or your home. More accurate for testosterone, cortisol, and insulin. Cost: £39–250+. Medichecks and Forth offer a venous upgrade for £25–45 on top of their kit price.
What a comprehensive health panel should include
| Marker | What it tells you |
|---|---|
| Full blood count (FBC) | Red/white blood cells, platelets — anaemia, infection, immune function |
| Liver function (LFTs) | ALT, AST, GGT, bilirubin — liver health, alcohol impact |
| Kidney function | Creatinine, eGFR, urea — kidney filtering capacity |
| Thyroid (TSH) | Underactive/overactive thyroid screening |
| Cholesterol | Total, HDL, LDL, triglycerides — cardiovascular risk |
| Iron/ferritin | Iron stores — fatigue, anaemia |
| Vitamin D | Deficiency is very common in the UK (especially Oct–Mar) |
| Vitamin B12 | Energy, nerve function — especially relevant for vegetarians/vegans |
| HbA1c | Diabetes screening — average blood sugar over 3 months |
| CRP | Inflammation marker — infection, chronic disease |
A panel covering all of these costs £49–89 from most online providers.
Home finger-prick kits are processed in the same UKAS-accredited laboratories that process GP blood tests. The main accuracy risk is sample collection, not lab quality — warm your hands, don't squeeze too hard, and collect first thing in the morning for hormones.
How much do private blood tests cost?
| Test type | Price range | Who it's for |
|---|---|---|
| Single marker (e.g., vitamin D) | £25–39 | Quick check on one concern |
| General health panel | £39–89 | Annual health MOT |
| Advanced panel (hormones + markers) | £89–199 | Detailed health picture |
| Female hormone panel | £69–149 | Menopause, fertility, PCOS |
| Male hormone panel | £59–129 | Testosterone, energy, mood |
| Full clinic health assessment | £199–800+ | In-person with doctor review |
Prices from Medichecks, Forth, Thriva, and Vitall as of April 2026. Medichecks frequently runs 20–30% discount codes.

When private blood testing is common
- Annual health check — for people over 30 wanting to catch issues early
- Persistent fatigue — ruling out thyroid, iron, vitamin D, and B12 deficiency
- Starting a new diet or supplement — baseline before, retest after 3 months
- Family history — diabetes, cholesterol, thyroid conditions
- Before weight loss medication — most GLP-1 prescribers require baseline bloods
Accuracy and accreditation
All reputable providers use UKAS-accredited or CQC-registered laboratories. Check for accreditation before ordering. Finger-prick kits are clinically validated and processed in the same labs as GP blood tests.
