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

How this test can help

Select the area and specific problem to see exactly how we approach it through this test.

Energy & fatigue

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.

From data to action

Precise markers mean precise actions. Once the test shows what is actually driving the pattern, the plan can target that, instead of guessing.

Where we focus

The Organic Acids Test is not a single reading, it reads four connected layers of your metabolism at once.

1 urine sample · ~70 metabolites
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.

Read together, these four layers show how you make energy, what your microbes are producing, and where a nutrient is running short.

Often paired with

Most people run one test. Where a second genuinely adds an answer the first cannot give, this is the pair we reach for.

The people behind your results

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

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.

The evidence

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.
