Detective Health · Targeted Clinical Assessments
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
Not sure which fits?
Describe what you're dealing with — the concierge will help you identify whether a targeted assessment or the full TDG programme makes more sense for your situation, and which assessment is most relevant.
