Mosaic Diagnostics Urine Organic Acid Test (OAT):

The Mosaic Diagnostics Urine Organic Acid Test (OAT) is used to take a metabolic snapshot of the body’s functions through the analysis of waste products passed in the urine. Acids present in the urine at certain levels can be indicators of toxicity or even give a reading of how chemical functions are performing at a cellular level. The test can be used to provide markers for inflammation, neurotoxicity, vitamin D deficiency, bone function, exposure to parabens, mitochondrial dysfunction, beneficial bacteria, glutathione deficiency, yeast overgrowth, and the functioning of the Krebs cycle.

Using the Urine Organic Acid Test (OAT) is simple. The specimen is sent to Mosaic Diagnostics Laboratory in a prepaid envelope. All test kits and lab fees are paid through Agape Nutrition, so there’s no need to bill medical insurers. All paperwork can be submitted via the mail or online and results are available between three and four weeks after processing.

    New Markers: Analyte List


    Quinolinic Acid - Marker for Inflammation and Neurotoxicity
    Quinolinic acid is an organic acid derived from the amino acid tryptophan and can be neurotoxic at high levels. Excitotoxic substances like quinolinic acid may stimulate nerve cells so much that the nerve cells die. Brain toxicity due to quinolinic acid has been implicated in Alzheimer's disease, autism, Huntington's disease, stroke, dementia from old age, depression, HIV-associated dementia, and schizophrenia.


    Inorganic Phosphate - Marker for Bone Function / Vitamin D Deficiency
    Low phosphate is associated with hypoparathyroidism, pseudohypoparathyroidism, low nutritional phosphate intake, parathyroidectomy, and vitamin D deficiency.


    4-Hydroxybenzoic Acid - Marker for Exposure to Parabens
    4-Hydroxybenzoic acid is a metabolite of methylparaben, an anti-fungal agent, and a popular preservative in food and cosmetics. Parabens may be linked to mitochondrial failure due to depletion of cellular ATP through uncoupling of oxidative phosphorylation. They may also be produced from the microbial metabolism of polyphenols in the diet. Parabens have been found at high levels in breast cancer samples, but a definitive relationship with breast cancer has not been demonstrated.


    4-Hydroxyhippuric Acid - Marker for Exposure to Parabens
    4-Hydroxyhippuric, a glycine conjugate of 4-hydroxybenzoic acid, is a metabolite of methylparaben. This compound is increased from the intake of fruits containing polyphenols rich in anthocyanins, flavonols, and hydroxycinnamates, which are metabolized by gastrointestinal bacteria. 4-Hydroxyhippuric acid has been found to be an inhibitor of Calcium-ATPase in end-stage renal failure.


    Malic Acid - Marker for Mitochondrial Dysfunction
    When malic acid is simultaneously elevated with citric, fumaric, and alpha-ketoglutaric acids, it strongly suggests cytochrome C oxidase deficiency, indicating dysfunction in the mitochondrial energy pathways.


    DHPPA - Marker for Beneficial Bacteria

    Harmless or beneficial bacteria such as Lactobacilli, Bifidobacteria, and E. coli mediate the breakdown of chlorogenic acid to 3,4-dihydroxy phenyl propionic acid (DHPPA). High values of DHPPA are associated with increased amounts of these bacteria in the gastrointestinal tract.


    N-acetylcysteine (NAC) - Marker for Glutathione Precursor & Chelating Agent
    N-acetylcysteine is a powerful antioxidant that acts to increase the glutathione reserves in the body. It is found in body fluids but is also used as a nutritional supplement. N-acetylcysteine reduces the toxicity of drugs like acetaminophen (Tylenol) and protects against the toxicity of mercury and other heavy metals. Low levels could indicate a glutathione deficiency.


    Quinolinic Acid / 5-HIAA Ratio - Marker for Neurotoxicity and Inflammation

    A high ratio of quinolinic acid to the tryptophan metabolite 5-hydroxy indole-acetic acid indicates excessive inflammation due to recurrent infections, excessive tryptophan intake, immune overstimulation, excessive adrenal production of cortisol, or excessive exposure to phthalates.


    Other Important Markers

    Besides the new markers, the OAT still evaluates other important compounds including the Krebs cycle and neurotransmitters. This reliable test detects the overgrowth of yeast and a bacteria species, Clostridia, commonly missed by conventional culture methods. These organisms and their metabolites can produce or magnify symptoms of many medical conditions. Identification of a yeast or bacterial overgrowth paired with a successful treatment can increase the chance of recovery.


    Yeast: Intestinal growth of yeast & fungi, including Candida, are measured via by-product. High levels indicate an overgrowth.


    Bacterial: Intestinal growth of bacteria, including Clostridia species, is measured via by-product. High levels indicate an overgrowth.


    Oxalates: Elevations may indicate an excess of foods high in oxalates or Vitamin C, digestive disease, B6 deficiency, or intestinal yeast growth. Genetic markers indicate possible hyperoxaluria.


    Glycolysis: Elevations may result from infection, exercise, or B vitamin deficiency. Very high levels may result from genetic metabolic disorders.


    Oxalate Control


    Krebs cycle: Abnormalities may result from nutrient deficiencies, microbial overgrowth, or glutathione (GSH) deficiency.

    2-oxoglutaric: Low levels may result from the regeneration of amino acids to remove excess ammonia.


    Neurotransmitters: Metabolites of dopamine, norepinephrine, adrenaline, and serotonin are measured. Abnormalities may result from stress or poor detoxification, depression, toxic metal exposure, and rarely, specific tumors.


    Pyrimidines: Slight elevations occur from folic acid deficiency. Significant abnormalities can indicate possible genetic dysfunction.


    Fatty acids: Abnormalities can occur from ketogenic diets or fasting, intake of medium-chain triglycerides, carnitine deficiency, or genetic disease.


    Toxic indicators: Abnormalities can occur from deficiency of glutathione, excess ammonia, and aspartame ingestion.


    Vitamin indicators: Abnormalities involving B12, B6, biotin, ascorbic acid are measured. Amino acids: Abnormalities indicate a possible genetic error.


    Miscellaneous: Abnormalities can indicate GI microbial activity or genetic disease.
