Organic Acids Test (OAT)
76 metabolic markers from a single urine sample
$300–$400
~14 business days
The Organic Acids Test (OAT) from Mosaic Diagnostics is one of the most comprehensive metabolic snapshots available, measuring 76 organic acid markers in urine that reflect mitochondrial function, neurotransmitter metabolism, nutrient status, oxidative stress, and microbial overgrowth.
Organic acids are metabolic byproducts that, when elevated, indicate specific enzyme deficiencies, nutrient needs, or microbial imbalances. OAT is particularly valuable for identifying mitochondrial dysfunction, yeast and bacterial overgrowth, and neurotransmitter imbalances that drive fatigue, brain fog, and mood disorders.
What It Measures
Mitochondrial function and energy production markers
Neurotransmitter metabolites (serotonin, dopamine, norepinephrine)
Yeast and bacterial overgrowth markers (arabinose, HPHPA)
Oxalate levels and oxalate metabolism
Nutritional markers (B vitamins, CoQ10, glutathione)
Krebs cycle intermediates
Detoxification capacity markers
Why Gabriel Recommends It
OAT is the metabolic test that connects the dots conventional medicine misses. A patient with fatigue might have normal bloodwork but an OAT showing crippled mitochondrial function and massive yeast overgrowth. Gabriel uses OAT data to identify the specific biochemical bottlenecks driving your symptoms and to design targeted supplementation protocols — not shotgun approaches.
What to Expect
Collect a first-morning urine sample at home using the provided kit. Ship it in the prepaid envelope. Results arrive in approximately 14 business days with detailed marker analysis. The report can be complex — uploading to Gabriel ensures you get a clear, actionable naturopathic interpretation.
How Gabriel Interprets This
Conventional practitioners read these results through a disease-focused lens — looking for what's broken. Gabriel reads them through a holistic lens — looking for what's out of balance and how to restore it. We see optimal ranges, not just "normal" ranges. We connect findings across all your diagnostics to reveal patterns that siloed specialists miss.

Frequently Asked Questions
OAT analyzes 76+ metabolic byproducts in your urine to assess energy production, gut health, neurotransmitter levels, nutrient status, detoxification capacity, and oxidative stress. Think of it as a metabolic snapshot that reveals how efficiently your body's biochemical machinery is running.
Blood tests measure what's circulating. OAT measures what your cells are actually doing with those nutrients. It can detect mitochondrial dysfunction, Candida overgrowth, bacterial dysbiosis, B-vitamin deficiencies, glutathione depletion, and neurotransmitter imbalances that standard blood panels miss entirely.
You collect a first-morning urine sample at home using the provided kit and mail it to the lab. No special preparation is needed, though your practitioner may advise temporarily pausing certain supplements that could affect results.
Typically $300-400 depending on the lab (Great Plains/MosaicDX, Genova, or Diagnostic Solutions). Insurance rarely covers it, but HSA/FSA funds usually apply. Many practitioners consider it one of the highest-value functional medicine tests for the price.
Anyone with chronic fatigue, brain fog, digestive issues, mood disorders, recurring infections, or unexplained symptoms that standard testing hasn't resolved. It's particularly valuable for children with autism spectrum conditions, people with suspected Candida overgrowth, and anyone with mitochondrial concerns.
