Organic Acids (OAT) Test by Mosaic Labs (Formally Great Plains Labs
The Organic Acids Test (OAT) provides detailed information about your metabolic health. This urine-based test helps identify gut imbalances, nutrient deficiencies, neurotransmitter production issues, and metabolic inefficiencies.
What Does the OAT Test Measure?
- Gut Health: Identifies yeast and bacterial imbalances that can disrupt digestion.
- Energy Production: Pinpoints issues in mitochondrial function that affect energy levels.
- Nutritional Deficiencies: Highlights missing vitamins, amino acids, and antioxidants critical for health.
- Neurotransmitters: Assesses your body’s ability to correctly produce neurotransmitters that can affect mood and exacerbate other neurological issues.
- Oxalates: One of the few tests to include oxalates, offering insights into early kidney stone development before symptoms arise.
Who Should Take The Organic Acid Test?
This test is ideal for those experiencing fatigue, mood changes, digestive concerns, or hard-to-explain symptoms. It can guide targeted health improvements based on your unique metabolic makeup.
