Detective Health · Targeted Clinical Assessments

The Nutritional Investigation
Specialist Medicine
Doesn't Do

Every specialist in medicine has a domain — the fertility clinic, the surgeon, the psychiatrist, the implantologist, the aesthetics practitioner. What none of them do is assess the nutritional and inflammatory foundation on which their interventions operate. These assessments fill that gap — targeted, specific, and built around the procedure or context you're already navigating.

Specific investigations for specific clinical contexts

Unlike the TDG Five-Test Programme — which maps the full picture across hormones, gut, metabolism, nutrition, and immunity — targeted assessments address a single, specific clinical context. They are for people who are already engaged with a specialist clinical pathway (IVF, surgery, aesthetic treatment, psychiatric care) and want to ensure the nutritional foundation is optimised for that specific context.

Each assessment is built around the evidence base for that context — the specific nutrients shown to affect surgical healing, egg quality, osseointegration, neurotransmitter synthesis, or collagen production. Not a general health check. A specific investigation with a specific clinical rationale.

🎯
Context-specific
Each assessment is built around the evidence for that exact clinical situation — not a generic health panel repurposed.
📋
Written protocol
Every assessment produces a written report with specific supplement doses, forms, timing, and dietary priorities for your situation.
⏱️
Timely
Designed to be completed in the window before your procedure or alongside your current clinical pathway — not months of investigation.

Six specific contexts — six targeted investigations

Surgery · Orthopaedics · Sports Injury
Pre-Surgical Optimisation
For anyone with an elective procedure in the next 6–12 weeks

Key markers
Ferritin · Zinc · Vitamin C · Vitamin D · CRP · Albumin (protein status)

The wound healing cascade has specific nutritional requirements at every phase. None are assessed in the NHS pre-operative pathway. This assessment maps and corrects them in the 6–8 weeks before surgery — or supports rehabilitation after sports injury.

Fertility · IVF · Natural Conception
Pre-Conception Assessment
For those planning IVF, IUI, or natural conception — both partners

Key markers
CoQ10 · MTHFR variants · Vitamin D · Selenium · Zinc · Homocysteine · Thyroid (TSH, T3, T4, TPO, TgAb)

Egg quality, uterine receptivity, and implantation success are all nutritionally dependent. Nobody at the fertility clinic checks CoQ10, MTHFR status, or follicular selenium. This assessment covers the 90-day pre-conception window that matches follicular development time — for both partners.

Depression · Anxiety · Psychiatric Medication
Mental Health Nutritional Assessment
Before or alongside psychiatric treatment — with or without medication

Key markers
B12 functional status · MTHFR · Zinc · EPA omega-3 · CRP · Ferritin · Full thyroid including antibodies · Vitamin D

Before the antidepressant prescription, nobody checks these. They are documented, correctable nutritional drivers of depression and anxiety — and of antidepressant non-response. The assessment maps what's missing, identifies inflammatory vs methylation vs nutritional subtypes, and produces a specific intervention plan.

Dental Implants · Osseointegration
Pre-Implant Optimisation
For anyone planning dental implants in the next 6–12 weeks

Key markers
Vitamin D · Vitamin K2 · Zinc · Magnesium · CRP · HbA1c · Vitamin C

A £2,000 implant depends on osseointegration — bone fusing with titanium. This is a nutritionally dependent biological process. Implant failure rates vary significantly with vitamin D status, zinc, and systemic inflammatory load. Nobody checks these before placement. An 8-week preparation protocol changes the biology the implant is placed into.

Microneedling · Laser · Fillers · Chemical Peels
Pre-Procedure Optimisation (Aesthetics)
For those investing in aesthetic treatment courses

Key markers
Vitamin C · Ferritin · Zinc · CRP · Oestrogen / Progesterone · Cortisol · Vitamin D

Aesthetic procedures work by stimulating the body's repair mechanisms. The nutritional and hormonal foundation on which they operate determines how well they work and how long results last. Elevated CRP accelerates hyaluronidase — degrading filler faster. Low ferritin impairs collagen synthesis. This assessment maps and corrects both.

Biological Age · Longevity · Healthspan
DH Longevity Investigation
For those who want to measure and modify their pace of ageing

Key markers
DunedinPACE · OMICm Age (Harvard) · SYMPHONYAge · 110+ metabolomic biomarkers · Immunosenescence · Epigenetic disease risk

Not a telomere saliva kit. Clinical-grade biological age testing using DNA methylation clocks validated against mortality data — combined with 110+ metabolomic biomarkers showing exactly what is driving your pace of ageing and what to do about it. DunedinPACE is sensitive to intervention — making 12-month retesting a meaningful outcome measurement.

Nutrition · Metabolic Typing · Personalised Diet
Metabolic Natures Programme
£265

Your Metabolic Nature determines how you process macronutrients, respond to stress, recover from exercise, and thrive on different dietary patterns. This programme identifies your type through functional intake assessment, builds your personalised foods list, 7-day menu plan, and recipe library — then supports implementation through the DH Clinical Concierge for ongoing between-session guidance. What used to require weekly sessions is now delivered as a complete programme.

Which is right for you?

A targeted assessment addresses a single, specific clinical context. The TDG Five-Test Programme maps the full picture across five functional domains. Both are valid entry points — the right choice depends on what you're navigating right now.

Targeted Assessment
Specific clinical context — surgery, IVF, mental health, aesthetics
Completed in 4–6 weeks with blood draw
£295–£750 depending on assessment
Written report and protocol for that specific context
Can be followed by TDG programme if deeper investigation needed
Right if you have a specific procedure or context in focus
TDG Five-Test Programme
Full picture — hormones, gut, metabolism, nutrition, immunity
DUTCH Plus · GI-MAP · OAT · IgG Food MAP · Blood Chemistry
£3,500 — complete clinical investigation
Multi-session clinical programme with Stephen
Ongoing support and protocol adjustment
Right if you have multi-system unresolved symptoms
