Private Blood Tests for Hair Loss London 2026: The Comprehensive Diagnostic Panel

By the medical team at The London PRP Clinic by The Wellness. Last reviewed April 2026. GMC-registered doctors. Marylebone (2 minutes from Baker Street).

At a glance

The single most common reason hair loss treatment fails is undiagnosed underlying medical cause. Iron deficiency, sub-clinical hypothyroidism, vitamin D deficiency, hormonal imbalance, polycystic ovary syndrome, perimenopause, post-pregnancy hormonal change, vitamin B12 deficiency, and autoimmune conditions all drive hair loss, and all require specific blood testing to identify. The standard NHS GP blood panel is not designed for hair loss diagnosis and frequently misses contributing factors. At The London PRP Clinic by The Wellness, the Comprehensive Hair Loss Blood Panel costs £445 as part of the initial consultation package, covering 9 critical markers across hormonal, nutritional, metabolic, and autoimmune categories. Standalone blood panels without consultation are available from £195. Pricing aligns with London's leading specialist hair loss clinics including Hair GP (£300 specialist consultation including bloods), Wimpole Her, Rejuvence Clinic, Dr Haus Dermatology on Harley Street, and the London Dermatology Centre. Every panel is reviewed by a GMC-registered doctor with structured diagnosis and treatment plan.

The reason most NHS GP blood tests miss hair loss causes is straightforward. The standard NHS hair loss panel typically covers TSH (thyroid), full blood count, and ferritin. The reference range called "normal" for ferritin in NHS labs is typically 15-300 mcg/L, which classifies a patient with ferritin of 20 mcg/L as normal. The published hair loss specialist consensus, supported by the British Association of Dermatologists 2024 guidance and the Journal of the American Academy of Dermatology systematic reviews, is that ferritin must be above 70 mcg/L for optimal hair growth. The patient told their bloods are "normal" by their NHS GP at ferritin 20 mcg/L is, in fact, severely iron-deficient for hair growth purposes. The same pattern affects thyroid function (sub-clinical hypothyroidism missed at standard ranges), vitamin D (UK winter deficiency epidemic missed at routine screening), hormones (free testosterone and SHBG not routinely tested), and autoimmune markers. The comprehensive panel at The London PRP Clinic by The Wellness identifies what the standard panels miss.

What does the comprehensive hair loss blood panel cover?

The structured panel at The London PRP Clinic by The Wellness covers 14 specific markers selected based on the published clinical evidence for hair loss diagnosis. The panel is informed by the British Association of Dermatologists 2024 guidance, the Journal of Investigative Dermatology systematic reviews, the International Journal of Trichology consensus statements, and the Endocrinology and Metabolism Clinics of North America evidence on hormonal hair loss.

Iron status (3 markers). Ferritin is the storage form of iron and the most sensitive marker for hair loss. Target above 70 mcg/L for optimal hair growth, supported by the 2008 Park study in the Journal of the American Academy of Dermatology and subsequent confirmatory data. Serum iron and total iron binding capacity (TIBC) provide context for iron status. Transferrin saturation gives the percentage of transferrin carrying iron.

Full blood count (FBC). Haemoglobin reveals anaemia (frank iron deficiency, B12 deficiency, or other causes). White cell count and platelet count provide general health screening.

Thyroid function (3 markers). TSH (thyroid stimulating hormone) is the most sensitive marker for thyroid dysfunction. Sub-clinical hypothyroidism with TSH 4.5-10 mIU/L and normal T4 frequently drives hair loss and is missed when only TSH is tested with broad reference ranges. Free T4 (free thyroxine) measures the active thyroid hormone level. Anti-TPO antibodies identify autoimmune thyroid disease (Hashimoto's, Graves'), which is associated with both alopecia areata and female pattern hair loss.

Vitamin status (3 markers). Vitamin D (25-hydroxy vitamin D) target above 50 ng/mL for optimal hair growth. UK adult deficiency epidemic affects more than 50% of population in winter. Vitamin B12 target above 400 pg/mL (the lower NHS reference range of 200 pg/mL is associated with hair loss in published series). Folate complements B12 testing.

Hormonal panel (4 markers in women, 3 in men). Free testosterone and sex hormone binding globulin (SHBG) calculated together to give the free androgen index. Critical for diagnosing PCOS-related hair loss in women and androgen optimization in men. DHEAS (dehydroepiandrosterone sulphate) reflects adrenal androgen production. Prolactin elevation can drive hair loss. Oestradiol with FSH and LH where perimenopause or menopause assessment indicated. DHT (dihydrotestosterone) testing where finasteride therapy considered.

Inflammatory markers. C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) screen for systemic inflammation that can drive hair loss.

Autoimmune markers. ANA (antinuclear antibodies) where autoimmune cause suspected. Specific antibody profiling where indicated by clinical picture.

Metabolic panel. HbA1c (glycated haemoglobin) screens for diabetes and insulin resistance, particularly relevant in PCOS and metabolic syndrome where insulin resistance contributes to androgen excess. Lipid profile provides cardiovascular and metabolic context.

Specific markers in selected cases. Coeliac screen (anti-tissue transglutaminase IgA) where coeliac disease suspected as cause of iron malabsorption and consequent hair loss. Vitamin A and zinc where deficiency suspected. Heavy metal screening in selected occupational or environmental exposure cases.

The 14-marker panel typically delivers actionable diagnostic information in 65-75% of female hair loss cases and 45-55% of male hair loss cases, with the remainder having predominantly genetic or stress-related causes that do not show abnormalities on blood testing.

Who needs comprehensive hair loss blood testing?

The published clinical evidence and our clinical experience identify nine patient groups who benefit substantially from comprehensive blood testing.

Group one: women with diffuse hair thinning. Female pattern hair loss, telogen effluvium, hormonal hair loss, and PCOS-related thinning all benefit from comprehensive blood diagnosis. The integration of hormonal, nutritional, and thyroid assessment delivers actionable findings in the majority of women presenting with diffuse thinning.

Group two: men with non-classical pattern hair loss. The man with diffuse thinning rather than classical Norwood pattern, or with rapid-onset shedding, or hair loss before age 25, often has an underlying contributing factor identifiable on bloods.

Group three: post-pregnancy hair loss persisting beyond 12 months. Postpartum telogen effluvium typically resolves at 6-12 months. Persistence beyond this suggests additional contributing factors (post-pregnancy iron deficiency, postpartum thyroiditis, hormonal change) requiring identification.

Group four: hair loss following GLP-1 weight loss medication. Ozempic, Wegovy, and Mounjaro hair loss reflects rapid weight loss, nutritional inadequacy, and metabolic stress. Comprehensive blood testing identifies which contributing factors require targeted intervention.

Group five: perimenopausal and menopausal women. Hormonal change drives hair loss alongside other symptoms. The integrated assessment guides HRT decisions alongside hair-specific treatment.

Group six: hair loss not responding to first-line treatment. Patients who have tried minoxidil, PRP elsewhere, or other treatments without response often have undiagnosed underlying factors.

Group seven: alopecia areata patients. The autoimmune workup identifies associated conditions (autoimmune thyroid disease, vitamin D deficiency, vitiligo) requiring management.

Group eight: patients on prescription medications associated with hair loss. Beta-blockers, certain antidepressants, statins, hormonal contraceptives, anabolic steroids, and others can drive hair loss. Comprehensive assessment identifies contributing factors and informs medication review.

Group nine: patients seeking PRP, ExoRevive, or hair transplant who want to optimise outcomes. Pre-treatment optimisation of nutritional and hormonal status delivers measurably better regenerative therapy response.

What is the pricing structure at The London PRP Clinic by The Wellness?

Comprehensive Hair Loss Initial Consultation Package: £445. Including the 30-minute consultation with a GMC-registered doctor, comprehensive medical history, focused examination, trichoscopic scalp examination, the 14-marker comprehensive blood panel, structured diagnosis with treatment plan, and follow-up review when results are available.

Standalone Comprehensive Hair Loss Blood Panel (results review by phone or video, no in-person consultation): £295. Including blood draw, full panel processing, and 15-minute results review with a GMC-registered doctor.

Targeted Mini Panel (5 most relevant markers based on clinical picture): £195. Including ferritin, TSH plus free T4, vitamin D, free testosterone with SHBG. For patients with a specific suspected cause.

Repeat Blood Panel (for monitoring): £195 every 3-6 months as appropriate.

Specialist additional testing on request. ANA panel £75. Coeliac antibodies £85. DHT £95. HRT-relevant hormonal panel £195. Heavy metal screen £125.

Combined Comprehensive Hair Loss Initial Consultation Package plus PRP Course of Three: £1,795. Saves on combined pathway. The most popular package for new patients seeking integrated diagnostic plus regenerative treatment.

How this anchors against the London market in 2026. Hair GP charges £300 for a 50-minute female-led specialist hair loss consultation including dermoscopy, comprehensive blood panel review, and personalised treatment plan. Wimpole Her offers the comprehensive women's hair loss diagnostic with TrichoTest genetic testing alongside blood panels. Rejuvence Clinic offers in-depth blood testing panels alongside their treatment portfolio. Hair Loss London on Harley Street emphasises that "bloods done by the GP are usually insufficient as they will have usually been basic blood tests performed for reasons other than hair loss" and offers comprehensive panels. The London Dermatology Centre offers consultant dermatology-led hair loss assessment from £250-£450 plus separate blood panel costs. The London Skin and Hair Clinic offers specialist dermatology-led pathway. NHS hair loss assessment is variable, often limited, and frequently includes only 2-3 markers. Direct-to-consumer blood testing services (Medichecks, Thriva, Better You) offer hair loss panels from £79-£199 but do not include doctor-led interpretation, examination, or treatment planning. We sit firmly in the heart of the doctor-led premium tier with pricing that reflects the doctor-led integration, the structured trichoscopic examination, the comprehensive 14-marker panel, and the immediate treatment pathway access.

We do not undercut London's leading specialist hair loss clinics. We are a peer to them. The combination of doctor-led delivery, structured comprehensive blood panel, integrated regenerative treatment access, and integration with The Wellness primary care services positions us at the top of the doctor-led hair loss diagnostic tier in London 2026.

What does the diagnostic process actually deliver?

The structured pathway delivers six specific outputs.

Output one: identification of underlying medical contributors. The patient who arrives believing they have genetic hair loss often has identifiable medical contributors (iron deficiency, thyroid dysfunction, hormonal imbalance) that have been missed. Addressing these systemic factors transforms response to hair-specific treatment.

Output two: classification of the hair loss type. Female pattern hair loss responds to specific treatments (PRP, minoxidil, spironolactone). Telogen effluvium responds to trigger identification and nutritional support. Alopecia areata responds to immunomodulation. Scarring alopecia requires specialist management. Without classification, treatment is guesswork.

Output three: severity quantification. The Ludwig scale (women), Norwood-Hamilton scale (men), and SALT score (alopecia areata) provide validated measures for severity that inform prognosis and treatment selection.

Output four: trichoscopic findings. The magnified scalp examination reveals follicle miniaturisation patterns characteristic of androgenetic alopecia, exclamation mark hairs characteristic of alopecia areata, perifollicular signs of inflammation suggesting scarring alopecia, and yellow dots and black dots that further refine diagnosis.

Output five: personalised treatment plan. Combining the medical findings, hair-specific findings, and patient goals into a structured plan covering immediate interventions (iron supplementation, vitamin D, thyroid optimisation), regenerative treatment (PRP, ExoRevive, polynucleotides), prescription medications (topical and oral minoxidil, spironolactone, finasteride where appropriate), and long-term maintenance.

Output six: integration with broader health. Hair loss often reflects systemic factors. The integration with The Wellness primary care services means we address the underlying medical issues alongside the hair-specific treatment, delivering comprehensive care.

Why does The London PRP Clinic by The Wellness deliver better diagnostic outcomes than most clinics?

There are five reasons our hair loss diagnostic outcomes consistently exceed the typical clinic offering.

First, comprehensive 14-marker panel rather than basic 3-marker assessment. The depth of testing identifies what most clinics miss.

Second, hair-specific reference ranges rather than general health ranges. Ferritin "normal" at 20 mcg/L by NHS standards is severely deficient for hair growth. We interpret results against hair-specific evidence-based thresholds.

Third, doctor-led integrated review. The GMC-registered doctor reviews bloods alongside trichoscopic findings, medical history, and examination, integrating the diagnostic picture rather than treating bloods as standalone results.

Fourth, immediate treatment pathway access. Once diagnosis is established, patients can access PRP, ExoRevive, polynucleotide regenerative therapy, prescription medication, and HRT pathway through The Wellness women's health services in a single integrated clinic. Most blood-testing-only services require separate referral pathways.

Fifth, integration with broader health. The Wellness primary care services means we identify and address systemic conditions (thyroid disease, PCOS, perimenopause, autoimmune conditions, nutritional deficiency) as part of the standard pathway rather than the hair-specific treatment in isolation.

Frequently asked questions

How long do blood test results take? Same-week typically. Standard markers return in 24-48 hours. Specialist tests (ANA panels, specific antibody testing) take up to 7 days. We deliver structured diagnosis and treatment plan within 7 days of testing in most cases.

Do I need to fast for the bloods? Some markers (lipid profile, glucose, HbA1c) are best tested fasting. Others (thyroid, ferritin, vitamins) do not require fasting. We advise based on the specific panel.

Can I have the blood test without consultation? Yes. Standalone Comprehensive Hair Loss Blood Panel at £295 includes blood draw and 15-minute results review with a doctor. For full diagnostic and treatment planning, the Comprehensive Initial Consultation Package at £445 is recommended.

What if my GP already tested basic markers? We review prior bloods at the consultation. Where comprehensive panel adds substantially to what your GP has tested (which is almost always the case for hair loss), we recommend the comprehensive panel. Where prior bloods are recent and comprehensive, we save you costs by using existing results.

Will the blood tests cure my hair loss? The blood tests identify contributing factors. The treatment of those factors plus regenerative therapy delivers hair improvement. Blood tests alone do not cure hair loss; they enable effective treatment.

Does private medical insurance cover hair loss blood testing? Variable. Some UK insurers cover blood testing where ordered by an in-network specialist for medical (rather than aesthetic) hair loss. We provide structured invoicing.

What if my bloods are normal? In approximately 25-35% of cases (predominantly genetic androgenetic alopecia in men and women without contributing factors), bloods do not identify treatable causes. The treatment plan in these cases focuses on regenerative therapy (PRP, ExoRevive) and prescription medication (minoxidil, spironolactone where appropriate, finasteride where appropriate). Knowing that bloods are normal is itself valuable as it confirms the genetic-pattern diagnosis and informs realistic expectations.

How does The London PRP Clinic by The Wellness compare with Hair GP, Wimpole Her, Rejuvence, or Hair Loss London? We sit alongside these specialist providers as a doctor-led peer in the premium tier. Hair GP at £300 specialist consultation is a strong alternative for women specifically seeking female-doctor-led hair specialist pathway. The differentiators at The London PRP Clinic by The Wellness are: comprehensive 14-marker blood panel within the £445 initial package, integration with The Wellness primary care services for broader hormonal and metabolic health management, integrated access to all major regenerative options under one ecosystem, convenient Marylebone location, and multilingual care in five languages.

Should I do home blood testing first? Direct-to-consumer panels (Medichecks, Thriva, Better You) at £79-£199 are useful for general health screening. They are not adequate substitutes for specialist hair loss assessment because they lack the doctor-led trichoscopic examination, classification, and treatment plan. Many patients do home testing first then come to us for the integrated specialist assessment.
