Still not feeling right, even after doing the basics? You’re not alone, and it’s not in your head. Sometimes one more piece of the picture helps show why.
The OAT is a urine test that looks at the leftovers of your body’s chemistry. Every time your cells make energy, use a vitamin, or process a neurotransmitter, they leave small byproducts called organic acids. Measuring them shows how those processes are running at the level of the cell. Gut yeast and bacteria leave byproducts too, and those show up here as well.
Blood work shows what is circulating. The OAT shows what your cells are doing with it.
Only when it helps. Barbie recommends this test only after she has reviewed your history and your first results, and only when it would change what you do next. It is separate from the $539 New Leaf Mineral Reset, and it is not sold on this site.
What the report covers
- Yeast and fungal markers. Byproducts of Candida and other fungi, including markers tied to Aspergillus mold.
- Bacterial markers. Byproducts of gut bacteria, including Clostridia species, which can affect brain chemistry.
- Oxalate markers. Oxalates come from food, from the body’s own chemistry, and from some molds and yeast. High levels can be linked to joint pain, urinary discomfort and kidney stress.
- Glycolysis markers. How well your cells break down sugar for fuel.
- Mitochondrial markers. How well the Krebs cycle, the main energy engine inside each cell, is running.
- Neurotransmitter metabolites. Byproducts of dopamine, adrenaline and serotonin, which help show how brain chemistry is being processed.
- Folate metabolism markers. Clues about how the methylation pathway is working.
- Fat-burning and ketone markers. How well your body is using fat for energy.
- Nutritional markers. Functional signs of need for B12, B6, B2 (riboflavin), B5, biotin, vitamin C, CoQ10 and glutathione-related nutrients.
- Detoxification markers. Glutathione status, methylation and ammonia handling.
- Amino acid metabolites. How certain proteins are being broken down.
- Mineral metabolism. Phosphate, related to vitamin D and bone mineral balance.
When Barbie may consider it
- Fatigue that does not lift as minerals improve
- Numbness, tingling or other nerve symptoms
- Brain fog, low mood, anxiety, or focus and learning struggles
- Signs of yeast or gut imbalance
- A known or suspected mold exposure
- Joint pain or urinary burning that could be oxalate-related
- Progress that stalls on protocol
What it can and can’t tell you
It can show where energy production, nutrient use or brain chemistry may be under strain, and whether yeast or bacteria are adding to the load. It gives functional clues that blood work does not.
It can’t pinpoint where in the gut an overgrowth sits, and it does not name specific organisms the way the GI-MAP does. Results shift with recent food, supplements and hydration. A marker that reads high or low is a clue to follow, not a diagnosis.
How it fits with HTMA and the Functional Lab Panel
The HTMA shows mineral patterns and stress physiology. The Functional Lab Panel shows what is circulating in the blood. The OAT adds what happens inside the cell. It is most useful when minerals are being supported and something still does not add up. Because supplements change the nutritional markers, Barbie thinks about timing so the result answers the question being asked.
Practical notes
- An at-home kit. You collect your first urine of the morning and mail it to the lab.
- The kit lists a few foods and supplements to pause for a day or two beforehand. Barbie will tell you which apply to you.
- It can run on the same urine sample as the mycotoxin panel.
How Barbie explains it
“Your blood work tells us what is circulating. The OAT tells us what your cells are actually doing with it: how well you are making energy, whether your B vitamins are being used, and how your nervous system is processing what it gets. It helps me find what is driving a symptom instead of guessing.”
