Organic Acids Test

Roughly seventy metabolic markers from a single urine sample

  • ~70 urinary metabolites from one first-morning sample
  • Reads mitochondrial energy production at the chemistry level
  • Neurotransmitter turnover: dopamine, noradrenaline & serotonin
  • Flags gut yeast (Candida) and Clostridia overgrowth
  • Functional B-vitamin need and oxidative-stress load, quantified

Why this test

Why read your metabolism, not just your blood

A blood test tells you what is circulating. The Organic Acids Test tells you what your cells are actually doing with it. Organic acids are the by-products your metabolism leaves behind as it makes energy, recycles neurotransmitters, processes B-vitamins and deals with gut microbes — and they spill into urine in measurable amounts. Reading roughly 70 of them at once is a validated way to detect metabolic disturbances that a standard panel never surfaces (Van Noolen et al., 2020). That is where the explanation for unexplained fatigue, mood shifts or brain fog so often turns out to be hiding.

What you'll discover

What the Organic Acids Test reveals

One first-morning urine sample, read by metabolomic analysis, maps the by-products of your metabolism — how you make energy, recycle neurotransmitters, handle B-vitamins and host your gut microbes. Organic-acid profiling reliably identifies and quantifies these compounds to surface metabolic disturbances (Van Noolen et al., 2020).

Mitochondrial energy production — citric-acid-cycle and fatty-acid-oxidation intermediates
Neurotransmitter turnover — dopamine and noradrenaline (HVA, VMA) and serotonin (5-HIAA)
Yeast overgrowth — arabinose and related Candida markers
Bacterial dysbiosis — HPHPA and other Clostridia by-products
Oxidative-stress load — 8-OHdG, a marker of DNA oxidation
Functional B-vitamin and cofactor need — MMA (B12), FIGLU (folate), xanthurenate (B6)

Read by people, not algorithms

Every result is reviewed twice over

A lab number on its own changes nothing. What matters is who reads it — and your results pass through two layers of expertise before they ever shape your protocol.

Alessandra Ginsburg

IFM-certified Functional Nutrition Practitioner

Alessandra interprets every marker against your full clinical picture — your symptoms, history, lifestyle and goals — not against a generic reference range. She is the one who turns raw lab data into the specific, personalised actions in your protocol, and who decides when a finding warrants medical evaluation and a referral to a physician.

Nordic Laboratories

Nordic Laboratories

Specialist functional-medicine laboratory · since 1997 · 100+ countries

Your sample is processed by Nordic Laboratories, a specialist functional-medicine lab operating since 1997 across more than 100 countries. Their scientific team runs the validated PCR and metabolomic assays under strict quality control, so the data Alessandra works from is accurate, reproducible and clinically meaningful.

Where we focus

Where this test looks

The Organic Acids Test is not a single reading — it reads four connected layers of your metabolism at once, which is why it so often explains symptoms that seem to have nothing to do with one another.

Image

Mitochondrial energy

Citric-acid-cycle and fatty-acid-oxidation intermediates show where, along the energy-production line, your cells are running smoothly or stalling — a chemistry-level read on fatigue and stamina.

Image

Neurotransmitter turnover

HVA and VMA reflect dopamine and noradrenaline breakdown; 5-HIAA reflects serotonin. Together they show whether the pathways behind focus, drive and mood are running fast, slow or depleted.

Image

Gut microbial balance

Arabinose flags Candida yeast overgrowth and HPHPA flags Clostridia bacteria — microbial signals read directly from their metabolic by-products in urine, not inferred from symptoms.

Image

Oxidative stress & cofactor need

8-OHdG quantifies oxidative wear on your cells, while MMA, FIGLU and xanthurenate reveal which B-vitamins your biochemistry is functionally short of.

How this test can help

How the Organic Acids Test helps

Because metabolism sits beneath energy, mood, gut and ageing all at once, this single test reaches well past any one symptom. Here is where its findings most often reshape the plan.

Energy & fatigue

Persistent tirednessLow staminaPost-exertion crashesAfternoon slumps

Mitochondrial citric-acid-cycle and fatty-acid markers show where energy production is stalling, so we target the exact cofactors and nutrients that the chemistry says are missing rather than guessing.

What's included

More than a test

A lab result you can’t act on is just paper. Every functional test at FunctionAlps comes wrapped in the analysis, the human explanation and the plan that turn it into change.

The test

A clinically validated functional lab test, with the collection kit sent to your door.

Specialist analysis

Your sample is processed by the laboratory and returned as a full functional report.

A results call with our nutritionist

Alessandra walks you through every finding in plain language — what it means, and what it doesn’t.

Your recommendations, in the report

Written, personalised recommendations tied directly to your results — yours to keep.

A personalised plan

Foods to favour and avoid, the app to track it, tips to try, and protocols sequenced to you.

Targeted supplements

Practitioner-grade supplements matched precisely to what your results reveal.

Pre / pro / postbiotics — if needed

When the findings call for it, targeted biotics to rebalance and rebuild your flora.

In plain language

If DNA shows your potential and stool shows your microbial neighbourhood, OAT shows your engine running. Are your cells making enough energy ? Is your brain getting the building blocks for serotonin and dopamine ? Is something fermenting in your gut that should not be there ? Are you depleting nutrients faster than you are replacing them ? OAT answers those questions in a single urine sample.

Practicalities
Sample

First-morning urine, single collection at home

Preparation

Avoid vitamin C, B-vitamins and fish oil 24 to 48h before ; avoid apples, grapes, raisins and pears the day before

Turnaround

Roughly three weeks

After the test

Your results live in the FunctionAlps app

Findings do not sit in a PDF you never open again. They flow into your app, where your protocol, your daily tracking and your wearable data line up against what the test actually found.

  • Your protocol, built directly from the results
  • Track symptoms, food and energy against the markers that matter
  • Wearable and app data fine-tune the plan as you go
  • Re-test when it counts and watch the trend, not a single snapshot

The evidence

Grounded in the research

Every claim on this page is anchored in published, peer-reviewed science. The studies behind it:

References ground the science of each marker — they describe the biology and published outcomes, not a guarantee of individual results.

Functional testing at FunctionAlps is used to guide nutritional optimisation within ASCA and EMR scope. It is not a medical diagnostic tool. When findings warrant medical evaluation, we coordinate with a referring physician.
