If you’ve tried everything and still can’t get to the bottom of your symptoms, the Organic Acids Test might be the missing piece. The OAT is a comprehensive metabolic snapshot that reveals how well your body’s core systems are working — from energy production and gut health to nutrient status and detoxification.
At The Allergy Clinic, Rachel McAuslin uses the OAT to uncover patterns that other tests simply don’t pick up.
What Does the Organic Acids Test Measure?
The OAT analyses a urine sample for dozens of metabolic markers. It gives Rachel detailed information about:
- Gut health — yeast and bacterial overgrowth markers, including oxalates linked to Candida
- Mitochondrial function — how efficiently your cells are producing energy
- Neurotransmitter metabolism — markers related to dopamine, serotonin, and adrenaline
- Nutritional deficiencies — B vitamins, CoQ10, and other key nutrients
- Detoxification and oxidative stress — how well your body is clearing waste and managing inflammation
- Oxalate levels — which can affect pain, kidney health, and gut function
This combination of information in a single test is what makes the OAT so powerful — particularly for people with complex, overlapping symptoms.
Who Is the OAT For?
The Organic Acids Test is worth considering if you’re dealing with:
- Chronic fatigue or low energy that doesn’t improve with rest
- Brain fog, poor concentration, or mood disorders
- Suspected Candida or yeast overgrowth
- Anxiety, depression, or neurotransmitter imbalances
- Nutrient deficiencies that haven’t responded to supplementation
- Complex, hard-to-explain symptoms across multiple body systems
It’s particularly useful when other tests have come back normal but you know something isn’t right.
How Does the OAT Work?
The OAT uses a simple first-morning urine sample collected at home. The kit is organised through Rachel’s clinic and posted directly to the lab. Results take approximately two to three weeks and are always reviewed with Rachel in a follow-up consultation — she’ll walk you through what each marker means and how it connects to your symptoms.
No jargon, no overwhelm — just clear, actionable information.
The OAT is a functional urine test that measures dozens of metabolic markers — including gut health, energy production, neurotransmitter metabolism, nutritional deficiencies, and detoxification — giving a comprehensive picture of how your body is functioning at a cellular level.
Standard blood tests screen for disease markers. The OAT looks at metabolic function — how well your body is producing energy, clearing waste, absorbing nutrients, and maintaining gut balance. It often reveals issues that blood tests miss entirely.
Yes. You collect a first-morning urine sample at home using a kit organised through Rachel’s clinic. It’s simple, non-invasive, and posted directly to the lab.
Yes — the OAT includes specific markers for yeast and bacterial overgrowth, making it one of the most useful tests for people who suspect Candida is contributing to their symptoms.
Results typically come back within two to three weeks. Rachel will book a follow-up consultation to review everything with you and explain what the findings mean for your health plan.
