The Investigation · How the parts connect

Most practitioners test, then guess what it means.
We investigate first, then test what matters.

The order is the whole point. Everything below happens before a single sample is taken — and what it produces decides which tests are worth running, and in what sequence.

How the Detective Health investigation fits together The Case File intake produces a Health Status Report. The report decides which of the five functional tests to run and in what order. The analysers read those results into patterns. The patterns become one protocol delivered through a programme. AIdan runs beneath every stage answering questions, and the public Learn library sits alongside the whole sequence. STAGE 01 · BEFORE ANY TEST The Case File The full intake — health story, symptom burden, lifestyle, medication, movement, metabolic nature, toxin load, allostatic load. Read personally, not automated. STAGE 02 · THE OUTPUT OF THE CASE FILE Your Health Status Report Domain scores, system strengths and vulnerabilities, and a test priority order. decides WHICH tests, and in WHAT ORDER STAGE 03 · TEST WHAT THE REPORT POINTS AT Blood Chemistry GI-MAP DUTCH Plus Organic Acids HealthBeings IgG food panel (286 foods) STAGE 04 · THE INVESTIGATION SUITE The analysers read the results together Cross-test pattern recognition, functional ranges, and the conflict-resolution engine.

Reading the diagram

Five stages, one sequence

Nothing here is unusual on its own. What is unusual is the order — and that the sequence produces something that can be shown to be wrong.

01

Before any testThe Case File

A full intake: your health story and its timeline, a scored symptom burden across every system, lifestyle, medications and their nutrient depletions, movement and posture, metabolic nature, toxin exposure, and cumulative stress load.

Every form is read personally before your first consultation. Nothing is scored by machine and handed over unexamined.

02

What the Case File producesYour Health Status Report

A clinical picture built from the intake alone — domain scores, where your system is strong, where it is vulnerable, and a foundational protocol you can begin straight away.

And a test priority order. This is the part that saves money. Rather than running everything and sorting it out afterwards, the report says which tests will earn their cost for your specific presentation, and which sequence answers the most useful question first.

See an example Health Status Report, for a made-up client, with notes on each section.

03

Directed, not exhaustiveThe functional tests

Blood chemistry read against functional ranges rather than reference ranges; GI-MAP for the gut ecology and barrier; DUTCH Plus for hormones and their metabolites; organic acids for mitochondrial and neurotransmitter function; IgG for delayed food reactions.

Most people do not need all five at once. The report decides.

Only what the report points atIn priority order
04

The investigation suiteThe analysers

Results are not read one panel at a time. The analysers cross-reference them — a gut finding that explains a blood chemistry pattern, a hormone result that changes how an organic acid is interpreted — and a conflict-resolution engine reconciles recommendations that point in different directions.

This is the layer that turns five sets of numbers into one coherent picture instead of five separate opinions.

05

Delivered through a programmeOne protocol, and a written prediction

Diet, rest, exercise, stress and targeted supplementation, sequenced so the thing most in the way is addressed first.

And the part most frameworks leave out. Before the protocol starts, we write down what we expect to change, which markers would show it, and by when. At retest we check. One of the possible outcomes is that the prediction was not met — which is the only way any of this can be shown to be wrong.

See an example plan for the same made-up client: food, lifestyle, movement and supplements, with the evidence for each.

Sample written plan, made-up client: the plate, with protein, carbohydrate, starch and fat amounts, plain-words guidance and an evidence note.

The session
What this page is not claiming. That the framework is validated by controlled trials — it is not, and where categories or markers rest on clinical observation rather than trial evidence, the pages that describe them say so. What is well supported is that the approach someone can actually sustain is the one that works. The written prediction in stage five is the part that can come back not met.

The layer underneath everything

AIdan

Every stage above raises questions between appointments. What does this marker mean. Is this ingredient on my list. Why has my energy changed this week. I’m travelling on Thursday. Historically those questions either waited for the next session or went unasked.

AIdan answers them, at any hour, from this practice’s own clinical knowledge base — not from the open internet, and not from a general-purpose chatbot. It knows the framework, the ranges, and the reasoning that produced your protocol.

It refers rather than prescribes, states what it does not know, and never substitutes for the consultation.

Two ways in

The same investigation, from two sides

The Case File is both the thing a client goes through and the thing a practitioner can license. The depth is the point either way.

If you are a client

What you get
  • The full Case File intake
  • Your Health Status Report
  • Only the tests your report calls for
  • One protocol, not five opinions
  • A written prediction, checked at retest
  • AIdan between every session

If you are a practitioner

What you can license
  • The Case File intake suite
  • The analysers for all five panels
  • The conflict-resolution engine
  • Interpretation guides and diagrams
  • The TDG Clinical Manual
  • AIdan for your own practice
