UK Private Blood Test Guides
These guides are the "how it actually works" articles — the things that aren't about a specific test or a specific provider, but the questions every reader has before they buy. All UK-specific, primary-sourced, no medical advice.

Available guides
Private PSA / Prostate Blood Test UK (2026): When to Test, Costs, NHS vs Private
The PSA buyer cornerstone. UK informed-choice screening policy (50+, 45+ for higher-risk groups), age-specific reference ranges, free vs total PSA ratio, what raises PSA besides cancer, and the modern NHS pathway (MRI before biopsy since 2019). UK costs £29–£149. Honest about when private testing genuinely helps and when NHS is the right path.
Private STI Blood Test UK (2026): HIV, Syphilis, Hepatitis
The STI blood-test cornerstone. Window periods (HIV 4 weeks, syphilis 6 weeks, hepatitis 4–12 weeks), what blood covers vs what needs urine/swab (chlamydia, gonorrhoea), why NHS sexual health is usually the right first choice, and where private adds value (speed, privacy perception, specific combinations). UK costs £49–£299.
Private Coeliac Blood Test UK (2026): tTG-IgA, EMA, DGP — The Gluten Rule
The coeliac cornerstone. 1 in 100 UK adults have coeliac, only 1 in 4 are diagnosed. First-line tTG-IgA + total IgA testing (£29–£89 private). The critical gluten rule (must be eating gluten for 6+ weeks before testing). Path from positive blood test to NHS biopsy diagnosis. HLA-DQ2/DQ8 gene testing for the already-gluten-free scenario. Honest about NCGS and the limits of "food intolerance" panels.
Private Vitamin B12 & Folate Blood Test UK (2026): Active B12, MMA, Pernicious Anaemia
The B12 + folate cornerstone. One of the most-missed reversible causes of fatigue, neuropathy and brain fog. Total B12 vs active B12 (HoloTC), the grey zone (140–250 ng/L) that often gets dismissed as "normal", MMA and homocysteine, intrinsic factor antibodies for pernicious anaemia. Vegan, metformin, post-bariatric and older-adult risk groups. UK costs £29–£129. Why self-supplementation can mask diagnosis.
Private Cardiovascular Risk Test UK (2026): ApoB, Lp(a), Advanced Lipids
The advanced cardiovascular cornerstone. Why standard NHS cholesterol misses risk in 1 in 3 adults. ApoB (the better-than-LDL particle count) and Lp(a) (the once-in-a-lifetime, genetically determined risk factor present in 1 in 5 people). hs-CRP, HbA1c context, and the decision logic for when advanced lipid testing changes management. UK costs £49–£199. Following ESC 2022 guidance on universal Lp(a) screening.
Private Health Check UK (2026): Annual Blood Screen, Health MOT & Well Person Costs Compared
The annual-screen cornerstone. What a UK “private health check” or “Health MOT” actually includes, how the four tiers split (£89 home through £999 executive), and how the free NHS Health Check (40–74, every 5 years, cardiovascular only) compares with private packages. Provider-by-provider line-up across Medichecks, Forth, Thriva, Bluecrest, Randox and the hospital-based assessments, plus a match-the-package-to-the-buyer decision rubric by age, risk and goal. UK costs £89–£999.
Comprehensive Vitamin & Mineral Blood Test UK (2026): Full Micronutrient Panel Costs & What to Test
The micronutrient cornerstone. Which vitamins and minerals are actually blood-testable (and which aren’t — serum magnesium and blood vitamin C have real limits). The four-marker stack (vitamin D, B12, folate, ferritin) at £59–£89 captures most clinically meaningful UK deficiencies. When to step up to a comprehensive panel (malabsorption, restrictive diets, long-term PPIs/metformin, structured supplementation). Costs £49–£399 across UK providers.
Liver Health Blood Test UK (2026): MASLD, Fatty Liver, ALT, GGT
The MASLD-era liver cornerstone. NAFLD renamed to MASLD in 2023 and what that means. What each LFT marker actually does (ALT, AST, ALP, GGT, bilirubin). FIB-4 fibrosis scoring (NHS first-line triage). When raised ALT actually matters, lifestyle interventions with the strongest evidence, and the NHS pathway. UK costs £29–£250.
Cortisol Test UK (2026): Costs, Saliva vs Blood, What to Buy
The grounded cortisol guide. When cortisol testing genuinely helps (suspected Addison's or Cushing's, post-steroid axis check, documenting disrupted diurnal pattern) and why "adrenal fatigue" is not a UK recognised diagnosis. Saliva curves vs single morning serum, timing rules, comprehensive stress panels. UK costs £35–£189.
Private Blood Test London (2026): Same-Day Clinics, Costs, Walk-In and Home
The London-specific local-intent cornerstone. Walk-in clinics in Harley Street and the City, same-day options, home fingerprick logistics from London postcodes, where the major providers operate, and when the Harley Street premium is genuinely worth paying. UK costs £29–£1,500.

Menopause Blood Test UK (2026): What to Test, NHS vs Private, Costs Explained
The focused cornerstone on menopause testing specifically. What NICE actually says (over 45: don’t test; under 40: test properly), what markers genuinely help (FSH, oestradiol, AMH, thyroid), cycle-timing rules, UK costs (£39–£189), and how to read your results. Honest about when private testing solves a real problem and when it just satisfies the want for numbers your GP correctly didn’t order.
HRT Blood Tests UK (2026): What to Test, When, and Whether You Even Need To
The HRT-specific monitoring cornerstone. Why NICE doesn’t recommend routine HRT blood monitoring, the four situations where testing is genuinely useful (persistent symptoms, suspected non-absorption, above-licence dosing, testosterone monitoring), why finger-prick oestradiol on patches and gels gives unreliable results, the right test timing for each formulation, and a sensible baseline panel before starting HRT (thyroid + vitamin D + ferritin) for £80–£150 that catches the conditions that mimic menopause.
Allergy Blood Test UK (2026): What IgE Tests Actually Show, NHS vs Private, Costs
The map of the most confusing category in UK private health: what specific IgE actually tests, why skin-prick is the NHS first-line, and why IgG “food intolerance” panels are explicitly advised against by every major UK clinical body. Practical decision tree by symptom, UK costs (£89–£399 for legitimate IgE testing), and a clear explanation of component-resolved diagnostics (ALEX2, ISAC) for nuanced nut-allergy assessment.
Fertility Blood Test UK (2026): What to Test, NHS vs Private, Costs
The honest fertility cornerstone for the UK private market. AMH explained (and what it does and doesn’t predict). Full female panel timing (day 2–5), the PCOS biochemical pattern, male blood work and the critical reminder that semen analysis is the real first-line male fertility test. NHS workup criteria (12 months trying under 36; 6 months at 36+) and tightening IVF funding reality. Costs £49–£249. Five scenarios where private genuinely helps and three where it doesn’t.
Pre-IVF Blood Tests UK (2026): What Your Clinic Will Order and What You Can Prepare Privately
The IVF-specific cornerstone. The three panels that make up UK pre-IVF blood testing: HFEA-mandated virology (HIV, hep B, hep C — your clinic will draw these themselves), female reproductive baseline (rubella immunity, blood group, FBC, thyroid), and ovarian reserve workup (AMH plus antral follicle count). What is worth preparing privately before your clinic consultation (AMH, thyroid, vitamin D, ferritin) and what is wasted money (private HFEA virology — the clinic will repeat). Realistic UK costs: £150–£800 for full pre-IVF blood and consultation against the £5,000–£8,000 cycle cost.
Private Diabetes & HbA1c Test UK (2026): Cost, Providers, What to Test
The under-served screening cornerstone. UK type 2 diabetes affects ~1 in 14 adults; pre-diabetes ~1 in 8; large fractions go undiagnosed under 40 because NHS Health Checks don’t start until then. UK diagnostic thresholds (<42 normal, 42–47 pre-diabetes, 48+ diabetes), what to test beyond HbA1c (lipids, ALT, eGFR, optional insulin/HOMA-IR), costs £19–£149, and a practical next-steps guide for both pre-diabetic and diabetic ranges. Honest take on the CGM/Levels/ZOE “metabolic health” trend.
