Description
Our Organic Acids Test (OAT) – Microbiome & Dysbiosis Markers measures 20 organic acids linked to intestinal yeast, bacterial overgrowth, and fungal toxins. These imbalances can contribute to:
- Digestive discomfort, bloating, and constipation
- Fatigue and low energy
- Neurological and mood disorders
- Leaky gut syndrome
- Malabsorption of vitamins and minerals
Why This Gut Health Test Matters
The gut microbiome plays a vital role in digestion, nutrient absorption, immune balance, and even brain function.
Toxins produced by yeast, fungi, and certain bacteria can:
- Trigger inflammation and immune dysfunction
- Disrupt neurotransmitter balance
- Impair nutrient absorption
- Exacerbate food allergies and sensitivities
This test helps identify these imbalances early, so targeted treatment can restore gut health.
Conditions Associated With Dysbiosis
- Irritable bowel syndrome (IBS)
- Chronic fatigue syndrome (CFS)
- Autism spectrum disorders
- Depression, anxiety, and mood swings
- Recurrent yeast infections
- Small intestinal bacterial overgrowth (SIBO)
- Neurological and movement disorders
Markers Measured in This Panel
Yeast & Fungal Overgrowth
- Citramalic Acid – Linked to Saccharomyces or Propionibacterium overgrowth.
- 5-Hydroxy-methyl-furoic Acid, Furan-2,5-dicarboxylic Acid, Furancarbonylglycine – Aspergillus species markers.
- 3-Oxoglutaric Acid – Indicates possible yeast overgrowth.
- Tartaric Acid, Arabinose – Candida overgrowth; linked to leaky gut.
- Carboxycitric Acid – General fungal marker.
- Tricarballylic Acid – Byproduct of fumonisin mycotoxins (often from contaminated corn).
Bacterial Overgrowth & Dysbiosis
- Hippuric Acid – Bacterial byproduct from phenylalanine metabolism.
- 2-Hydroxyphenylacetic Acid, 4-Hydroxyphenylacetic Acid – Indicators of Clostridia overgrowth, possible SIBO or celiac disease.
- 4-Hydroxybenzoic Acid, 4-Hydroxyhippuric Acid – Linked to paraben exposure or dysbiosis.
- Benzoic Acid – Elevated in various bacterial overgrowth states.
- DHPPA – From beneficial bacteria metabolising chlorogenic acid.
- HPHPA – Overgrowth of Clostridia species; disrupts dopamine metabolism.
- 4-Cresol – Marker for Clostridium difficile overgrowth.
- 3-Indoleacetic Acid – Tryptophan byproduct from Clostridia.
- Phenylacetic Acid – General bacterial overgrowth marker.

Preparing for this test
WHL will send detailed collection, storage and return instructions with your test kit or appointment confirmation. Those test-specific instructions take priority.
Sample: Urine
Fasting: An overnight fast is usually not needed. Follow the kit’s food, drink and collection-timing instructions.
The collection time, container and storage depend on the test. Follow your WHL kit; do not switch between a spot sample and a 24-hour collection.
Do not stop prescribed medicines or prescribed supplements without advice from your treating clinician. Tell WHL about high-dose biotin; some tests need a longer pause. A short supplement pause does not remove all effects of long-term use.
If another test in the same order requires fasting, follow the combined instructions. Ask your clinician or WHL before fasting if you have diabetes, use glucose-lowering medicine, are pregnant, or are arranging testing for a child.
When to expect your results
Usually 3–10 days. This estimate starts when suitable samples reach the laboratory, not on the order or collection date. Shipping is additional. WHL will confirm any test-specific exception; a combined panel follows its slowest component.
Practical preparation tips
If fasting is requested, drink only plain water in your usual amounts. Do not have coffee, tea, juice, milk, energy drinks, sweets or chewing gum. Avoid smoking or vaping that morning. Book an early appointment and eat after collection.
For a planned blood test, avoid alcohol and unusually strenuous exercise for 24 hours, where practical, and sit quietly for about 15 minutes before collection. Tell WHL if you could not follow the preparation instructions.
Do not extend fasting or change prescribed medication on your own. Ask your clinician first if you have diabetes, need medicine with food, are pregnant, or are arranging testing for a child. WHL’s full test-specific instructions take priority.
