You paid for a comprehensive test. Don't let the results sit in a folder you don't fully understand. This tool gives you a personalised interpretation of every marker — plain English, clinical context, and clear next steps.

The interactive guide is offline while I update it.
The OAT guide is a browser-based tool — you enter your values, it interprets them. Personalised to your specific results, not generic functional medicine information that may or may not apply to you.
Every marker on every section of your OAT report is covered. The tool identifies which individual findings are clinically significant, detects cross-section patterns that only become visible when multiple markers are read together, and generates a prioritised action plan based on your specific combination of results.
01
Six sections, 40+ markers
Microbial overgrowth, oxalates, Krebs cycle, neurotransmitter metabolites, nutritional markers, and detoxification — every section of your report interpreted.
02
Pattern detection across sections
Five clinical patterns that only appear when markers across different sections are read together. The mitochondrial pattern. The yeast-energy cascade. The Clostridia question, checked against stool testing. The tryptophan steal.
03
Personalised action plan
Based on your specific results, the tool generates a prioritised intervention sequence. Not a generic protocol — a plan built from what your markers actually show.
04
Cross-test integration notes
The tool identifies where your OAT findings connect to your DUTCH, GI-MAP, and blood chemistry results — the patterns that only become visible across tests.
Sample marker interpretations
This is what interpretation actually looks like.
Each marker produces a clinical interpretation tailored to what your specific level means — not a definition of the marker, but what it means for you clinically.
Arabinose — Very High
A marker that can be raised for several reasons, including diet; I read it alongside the other results, not as a diagnosis of Candida. If yeast overgrowth is the likely explanation, I check the GI-MAP findings first. Options then include caprylic acid, oregano oil, berberine and S. boulardii, with sugar cut right back.
Succinic Acid (Krebs) — Elevated
A marker that can be raised for several reasons; I read it alongside the other results, not as a diagnosis. Succinate is processed by an enzyme that needs riboflavin (B2) and CoQ10, so those are the first things I ask about. Options include CoQ10 (ubiquinol) and riboflavin-5-phosphate, then a retest.
HPHPA — Elevated
HPHPA is a compound linked to some Clostridia species. Whether a urine level tells you anything about dopamine in the brain hasn’t been shown, so I don’t read it that way. The one independent study that compared it with stool testing couldn’t confirm it as a Clostridia marker (Daneberga 2021), so I check the stool test before acting. If an overgrowth is confirmed, options include probiotics, berberine and allicin.
MMA — Elevated · Serum B12 Normal
B12 is needed to clear methylmalonic acid (MMA), so a raised MMA with a normal serum B12 is a reason to look harder at B12; kidney function can also raise it. I confirm on blood before treating. Options include methylcobalamin, and checking absorption if there’s a gut history. Retest MMA afterwards.
Doses are set individually after testing, with your other medicines checked.
How it works

1
Purchase and download
After payment you receive an immediate download link. The guide is a single HTML file — no app, no account, no login. Open in Chrome, Safari, or any modern browser.
2
Open your OAT report alongside the tool
The tool mirrors the section structure of your OAT report. Work through each section, selecting your result level for each marker (Low / Normal / Borderline High / High / Very High).
3
Click Analyse My Results
The tool generates your personalised interpretation — individual marker findings, clinical patterns detected across sections, a priority action plan, and cross-test integration notes for your DUTCH, GI-MAP, and blood chemistry.

Return to it at every retest
The tool is yours to keep. Download it once, use it with every OAT you run. Track how your markers change over time as interventions take effect.
Is this for you?
Who this guide is — and isn't — designed for.
This guide is for you if
You have OAT results and want to understand what they mean — not just receive a protocol without context
You have persistent fatigue, brain fog, mood disorders, or chronic pain that conventional testing hasn't explained
You want to understand why your energy is poor despite normal blood tests
You have elevated yeast markers on a previous test and want to understand the downstream consequences
You run OATs regularly and want a consistent clinical interpretation framework
This guide is not a substitute for
Clinical assessment — if your results show critical findings, professional guidance is appropriate
Medical diagnosis — the OAT reveals functional patterns, not disease diagnoses
GP consultation — some findings (very high VMA, very high 5-HIAA) warrant medical investigation
The full TDG five-test programme — OAT alone does not replace the complete integrated clinical picture
The Organic Acids Test is one of the five tests in the TDG Five-Test Programme (£3,500), where it is read together with blood chemistry, GI-MAP, DUTCH Plus and the IgG Food MAP. If you already have OAT results, Results & Plan (£295) gives you a full read with a consultation, a plan and a follow-up.
