Choose Your Starting Point

From a free 3-minute quiz to a single GI-MAP test to the full programme — every option explained. No pressure, no upsell. Find what's right for where you are right now.

Every option below is built on the same clinical principle: data before decisions, mechanism before protocol, root cause before symptom management. The difference is scope — how much of the picture we're working with.

Step 0 — Start Here
The Free Gut Health Quiz
3 minutes · No email required to see results

Not sure where to start? The quiz identifies which gut pattern is most likely driving your symptoms — based on the same clinical framework used in the full TDG programme. It won't replace testing, but it gives you a direction before you invest anything.

  • 28 questions across digestive, immune, and nervous system patterns
  • Instant results — no waiting, no email required
  • Clear next step recommendation based on your pattern

3 minutes. Tells you which system needs attention most urgently.

Step 4 — Comprehensive Investigation
TDG Five-Test Programme
5 tests · 900+ data points · Every body system · Full clinical protocol

The complete Detective Health investigation. Five functional tests running simultaneously — GI-MAP, DUTCH Plus hormone panel, comprehensive blood chemistry, Organic Acids Test, and food sensitivity panel — interpreted together, with cross-referencing producing patterns no single test can identify. For clients whose symptoms extend beyond gut health, or where the RGS or GI-MAP entry has revealed a picture warranting broader investigation.

  • All five tests dispatched simultaneously
  • Cross-system clinical interpretation report
  • Full protocol across all systems in priority order
  • 90-minute results deep-dive session
  • Randox blood draw appointment arranged

If you've already had a consultation with me and I've recommended a specific test, you can order and pay for the test kit below. I'll register you with the lab, dispatch your kit, and contact you when results are ready.

GI-MAP with Zonulin
DNA-based stool analysis — pathogens, parasites, commensal microbiome, H. pylori, digestive enzyme output (elastase), gut immune markers (sIgA, calprotectin), and intestinal permeability (Zonulin). Home collection kit. 10–14 working days to results.
£395

DUTCH Plus Hormone Panel
Complete diurnal cortisol curve, oestrogen and its metabolites (2-OH / 4-OH / 16-OH pathways), progesterone, testosterone, DHEA, melatonin, and neurotransmitter-related organic acids. Dried urine — home collection.
£295
Order Kit →
Organic Acids Test — Mosaic OAT
Cellular energy and mitochondrial function, neurotransmitter metabolites (HVA, VMA, 5-HIAA), yeast and bacterial overgrowth markers (arabinose, HPHPA/Clostridia), B-vitamin functional status, detoxification markers, and oxidative stress. First morning urine — home collection.
£318
Order Kit →
Food Sensitivity Panel (IgG 200+)
200+ food-specific IgG antibodies — delayed immune reactions to foods that may be driving inflammation, gut symptoms, skin conditions, and brain fog without obvious immediate symptoms. Finger-prick blood spot — home collection.
£195
Order Kit →
Comprehensive Blood Chemistry (Randox)
150+ markers using functional reference ranges — full thyroid panel (TSH, fT3, fT4, rT3, antibodies), fasting insulin, full iron panel, inflammatory markers, vitamin D, B12, homocysteine, lipids, and metabolic markers. Requires a venous blood draw at a Randox clinic — I'll book your nearest appointment once registered.

SIBO Breath Test + GI-MAP + Zonulin
The whole-tract gut investigation. SIBO lactulose breath test measures hydrogen, methane, and H₂S gas from small intestinal bacterial overgrowth — the gut problem no stool test can find. Combined with GI-MAP and Zonulin for the complete picture. Nordic bundle pricing. 3-hour home breath test plus stool collection.
£509

Metabolomix+ Nutritional Profile
The comprehensive OAT upgrade — adds amino acid profile (neurotransmitter precursors including tryptophan, tyrosine, GABA), fatty acid balance (DHA, omega-3:6 ratio), and oxidative stress markers (8-OHdG DNA damage) to the full organic acid panel. For ADHD, anxiety, eating disorder recovery, and complex fatigue presentations. First morning urine — home collection. Genova Diagnostics.
£419

MycoTOX Profile — Mycotoxin Testing
11 mycotoxins from 40+ mould species using mass spectrometry. For treatment-resistant presentations, water damage or damp building history, unexplained cognitive symptoms, chronic sinusitis, or gut protocols that keep failing. Ochratoxin A is the most commonly detected mycotoxin in UK practice. Creatine loading protocol required before collection. First morning urine — home collection. Mosaic Diagnostics.

EnviroTOX Complete — Full Environmental Toxin Panel
MycoTOX (11 mycotoxins) + ToxDetect (170+ environmental chemicals including phthalates, parabens, benzene derivatives, organophosphate pesticides, acrylamide) + Glyphosate and AMPA. The most comprehensive environmental toxin panel available in UK private practice. When the environmental picture is broader than mould alone — or when glyphosate exposure, dietary chemical burden, or occupational exposure are part of the clinical picture. Single first morning urine collection.
£819
Details →
GI-MAP + Zonulin + Mosaic OAT (Nordic Bundle)
Gut investigation and metabolic consequence in one order. GI-MAP identifies the organisms and immune picture in the colon; the OAT maps the downstream systemic impact — Clostridia markers, yeast metabolites, neurotransmitter pathway disruption, mitochondrial effect of dysbiosis. Nordic bundle pricing. Two home collections (stool + urine).

How test kit ordering works: When you click "Order Kit" you'll be taken to the booking page where you can pay and provide your details (name, date of birth, delivery address, email, and mobile number). I'll register you with the laboratory, arrange dispatch of your test kit, and contact you when your results are ready for interpretation. Test kit fees do not include clinical interpretation — that is arranged separately as part of your programme or as a stand-alone consultation. For the Randox blood chemistry panel, I'll need your postcode to find your nearest clinic and your preferred date and time for the blood draw appointment.

Deeper Investigation

When the Clinical Story Asks a More Specific Question

Not a premium tier. Not an upgrade. These are targeted investigations for presentations that need one more layer of investigation — the small intestine that the stool test can't reach, the mould exposure that explains why protocols aren't holding, the environmental chemical burden that's continuously disrupting the gut you've been trying to repair.

Small intestine · Breath test

SIBO Breath Testing

Hydrogen, methane, and H₂S from small intestinal bacterial overgrowth. The gut problem no stool test can find. For bloating within 90 minutes of eating, probiotics that worsen symptoms, histamine intolerance.

£509 (SIBO + GI-MAP + Zonulin bundle) →

Deeper nutritional · Urine

Metabolomix+

OAT plus amino acids, fatty acids (DHA/omega-3), and oxidative stress markers in one urine collection. For ADHD, anxiety, eating disorder recovery, and complex fatigue where the standard OAT raises questions the base panel can't answer.

£419 · Genova Diagnostics →

Mould exposure · Urine

MycoTOX Profile

11 mycotoxins from 40+ mould species by mass spectrometry. For treatment-resistant presentations, damp building history, cognitive symptoms, or gut dysbiosis that returns after treatment. Ochratoxin A is the most commonly found mycotoxin in UK clinical practice.

£398 · Mosaic Diagnostics →

Full environmental burden · Urine

EnviroTOX Complete

MycoTOX + ToxDetect (170+ environmental chemicals) + Glyphosate and AMPA in one collection. Glyphosate disrupts the gut microbiome via the shikimate pathway, increases intestinal permeability, and inhibits CYP450 detoxification. When the gut problem has an external driver.
