Organic Acid molecules in the urine are by-products of human metabolism providing non-invasive markers of gastrointestinal dysbiosis (bacterial and yeasts), oxalate metabolism, Krebs cycle metabolism, neurotransmitter function, ketone and fatty acid oxidation, detoxification, amino acid metabolism and in some cases indicators of nutritional status. In this test 73 gastrointestinal dysbiosis organic acids levels will be accurately determined.
