Organic Acids Test (OAT)
Urine Organic Acid Measurements
What is This Test?
You can review selected organic acids, which are metabolic byproducts measured in urine, with the Organic Acids Test (OAT). Diet, supplements, medicines, and other factors can affect results. These measurements do not by themselves diagnose nutritional deficiencies, infections, mental health conditions, or mitochondrial disease, and do not establish the cause of broad symptoms.
Confirm the exact panel, eligibility, preparation, and timing in your Fullscript order and current lab instructions. Kit instructions take priority over this general summary. Do not stop prescribed medicines without your clinician's guidance. Laboratory certification does not establish that every proposed clinical use is validated.
Biomarkers Tested
Gut Health & Dysbiosis
- Yeast and fungal metabolites
- Bacterial metabolites
- Clostridia markers
- Oxalate levels
Energy-Related Metabolites
- Krebs cycle intermediates
- Ketone and fatty acid metabolites
Nutritional Markers
- Selected vitamin-related metabolites
- Amino acid metabolites (not direct nutrient levels)
Other Metabolites
- Selected oxidative stress-related markers
- Neurotransmitter metabolites (not brain neurotransmitter levels)
What Should You Discuss Before Testing?
A Specific Clinical Question
Ask how urine organic acid results would inform your care and whether other testing is more appropriate.
Interpretation Limits
Do not use this panel alone to diagnose a condition or choose supplements.
Understanding Your Results
Your OAT results provide a comprehensive metabolic snapshot with clear markers and interpretations.
