The Test That FindsWhat Standard Blood Work Misses.
A comprehensive functional urine test that reads the metabolic activity of your cells — detecting imbalances in energy production, gut health, and brain chemistry that standard blood panels are not designed to identify.

Panel
What's Covered
Organic acids are metabolic byproducts excreted in urine. The Organic Acids Test (OAT) measures these compounds to provide a 'factory floor audit' of your metabolism, identifying where pathways are blocked or nutrients are deficient before disease states are established.
01Mitochondrial Function
Measures organic acids from the Krebs cycle to see how efficiently your cells convert food into energy (ATP), explaining unexplained fatigue and exercise intolerance.
02Gut Microbial Markers
Detects byproducts of Candida overgrowth, Clostridia activity, and general dysbiosis. This is often more sensitive for certain microbial activities than stool testing.
03Functional Nutrient Status
Identifies deficiencies in vitamins (like B12) and minerals that are actually impairing metabolic function, even if serum levels appear normal.
04Neurotransmitter Metabolism
Provides an indirect read on brain chemistry by measuring markers related to the synthesis and breakdown of dopamine, serotonin, and noradrenaline.
05Oxidative Stress & Detox
Reflects the degree of cellular oxidative damage and the efficiency of liver phase 1 and phase 2 detoxification pathways.
06Oxalate Levels
Detects accumulation of oxalates associated with kidney stones, joint pain, and chronic inflammatory conditions.
The OAT measures what your metabolism is actually producing — the functional outputs of biochemical pathways operating inside your cells.

Audience
Who It's For
The OAT is particularly useful for those whose symptoms are real but whose standard blood test results are unremarkable. It is appropriate for people experiencing:
- Chronic fatigue, low energy, or exercise intolerance with no identified cause on standard blood work
- Persistent gut symptoms like bloating or IBS seeking functional insight beyond a stool test
- Mood disorders, anxiety, brain fog, or cognitive decline wanting a read on neurotransmitter metabolism
- Recurrent infections or suspected immune dysfunction related to gut health
- Suspected Candida overgrowth, Clostridia activity, or leaky gut syndrome
- A desire for a comprehensive longevity assessment including cellular and metabolic functional data
03
Deliverable
Sample Collection and Clinical Reporting
The OAT is a non-invasive urine test. No blood draw or clinic visit is required for sample collection.
- A collection kit is provided at or sent from EGA following booking
- Requires a first-morning urine sample collected at home following specific dietary instructions
- Sample is returned to the laboratory by post in pre-paid packaging
- Your EGA clinician reviews the findings to provide a report with written commentary
- Findings are contextualised for your specific health goals and symptom picture

Difference
OAT and the Mechanisms of Ageing
The metabolic domains the OAT assesses are precisely the systems that deteriorate with age and are most modifiable through targeted intervention.
Mitochondrial Efficiency
Mitochondrial dysfunction is a hallmark of biological ageing and a driver of the energy decline and cognitive changes associated with getting older.
Inflammageing
Gut dysbiosis is a central mechanism of systemic inflammation and immune ageing, which the OAT quantifies via microbial byproducts.
Cellular Damage
Oxidative stress is a primary driver of epigenetic ageing. Measuring it allows for targeted antioxidant and lifestyle adjustments.
Complementary Data
The OAT fills in a picture of cellular health that no single other test covers, complementing blood biomarkers and physical performance testing.

Questions
Common Questions
Is the OAT a validated clinical test?
Yes. The OAT is a well-established functional medicine test used worldwide. The individual organic acid markers have validated clinical associations, though interpreting the patterns across the entire panel requires the clinical expertise we provide.
How is this different from a stool test?
A stool test identifies which organisms are present. The OAT detects their metabolic byproducts in urine, providing a different window into their activity, especially for Candida and Clostridia.
Can the OAT replace my standard blood tests?
No. They measure different things. Blood work assesses established disease states; the OAT assesses functional metabolic activity at the cellular level. They are complementary.
Do I need to fast before collection?
Yes. An overnight fast is required (water is fine). You must also avoid apples, grapes, pears, raisins, and cranberries for 48 hours before collection as they interfere with specific markers.
How long do results take?
Your clinician-reviewed report will be available in approximately 2 weeks from sample receipt at the laboratory.
Should I stop any supplements before the test?
Certain supplements can affect results. Your clinician will advise on adjustments based on your current protocol. Never stop prescribed medications without medical advice.
Do I need to attend the clinic?
No. Sample collection is completed at home. A follow-up consultation can be arranged if you wish to discuss your results in more detail with a specialist.
What can the OAT tell me about my mood?
It measures byproducts of neurotransmitter metabolism, such as those related to dopamine and serotonin, which can provide insight into the biochemical drivers of anxiety or low mood.
