    Organic Acids Test (OAT) - Nutritional & Metabolic Profile

    The Organic Acids Test (OAT) provides an accurate evaluation of intestinal yeast and bacteria. Abnormally high levels of these microorganisms can cause or worsen behavior disorders, hyperactivity, movement disorders, fatigue and immune function. Many people with chronic illnesses and neurological disorders often excrete several abnormal organic acids. The cause of these high levels could include: oral antibiotic use, high sugar diets, immune deficiencies, and genetic factors.

    If abnormalities are detected using the OAT, treatments can include supplements, such as vitamins and antioxidants, or dietary modification. Upon treatment, patients and practitioners have reported significant improvement such as decreased fatigue, regular bowel function, increased energy and alertness, increased concentration, improved verbal skills, less hyperactivity, and decreased abdominal pain. The OAT is strongly recommended as the initial screening test.

    The Microbial Organic Acids Test (MOAT) is ideal for follow-up to the OAT and is often recommended by practitioners looking for a specific abnormality, to monitor certain microbial imbalances, or to assess treatment efficacy.


    "After identifying a low serotonin level on an Organic Acid Test (a hallmark functional medicine test), A severely depressed and suicidal man began taking 100mg of 5htp twice a day (5htp is the direct precursor to serotonin). After 2 days, he said his depression virtually disappeared and he was no longer suicidal. I love when I can identify a biochemical glitch and someone can have such a profound emotional turn around."

    –Dr. Josh Friedman of Integrative Psychotherapy of Omaha

    "The Organic Acids Test has brought new meaning to my specialized practice in women's health. This test has allowed me to investigate more deeply the chronic issues that contribute to female related conditions like PMS, uterine fibroids, endometriosis, chronic UTIs and vulvodynia. I have had a great deal of success in treating complicated PMS cases that didn't respond to typical female hormone balancing therapies. Since utilizing the OAT, it has provided me with a variety of information to determine the underlying cause of female related issues. Some of the markers that I find valuable for women's health issues are the bacterial and yeast metabolites, oxalates, B vitamins, vitamin C, and pyroglutamic acid. I have been so impressed by this test that I can't help but want to spread the word about its uses for various women's health conditions!"

    10 Reasons Every Individual with a Special Needs Diagnosis (Autism, Aspergers, Attention Deficit, etc.) Should Do a Urine Organic Acid Test from The Great Plains Laboratory By Kurt Woeller, D.O.

    1. Evaluates for various fungal toxins, including specific markers for Candida. Many people rely on stool testing for candida diagnosis and miss the presence of candida toxins through the Organic Acid Test. Candida can create problems with brain function including goofiness, giddiness, and inappropriate laughter, as well as sensory problems and self-stimulatory behavior.

    2. Evaluates for two specific toxins related to clostridia bacteria – HPHPA and 4-cresol. Both of these toxins can inhibit a dopamine converting enzyme leading to excess dopamine and toxic reactions in the brain and nervous system. Behavior problems such as moodiness, irritability, aggression, self-injurious behavior, sleep problems and more is associated with clostridia bacteria overgrowth.

    3. The information from the Organic Acid Test helps to prioritize treatment intervention instead of just assuming everything is a candida problem. Treating for candida when clostridia bacteria are present can lead to problems, i.e. worsening behavior.

    4. Evaluates for high oxalates (oxalic acid). Oxalates are compounds found in many foods, and can be worsened from candida overgrowth. High oxalates are associated with pain in the joints, muscles, and connective tissues. They can also trap heavy metals (such as mercury, lead, and arsenic) in the body, and lead to mineral imbalances as well. Behavior and self-injurious tendencies have been associated with high oxalates.

    5. Evaluates for mitochondrial imbalances. The mitochondria are the energy factories of our cells. Often they are stressed because of toxins from yeast, bacteria, metals, and even oxalates. Mitochondrial dysfunction is seen in autism and can be a contributing factor to poor attention and cognitive skills, as well as poor physical growth and development.

    6. Evaluates for imbalances in Dopamine (HVA) and Norepinephrine (VMA). The balance between these two important brain chemicals is critical for attention, focusing, mood, calmness and other functions of the nervous system. Attention deficit problems are commonly associated with norepinephrine imbalances.

    7. Evaluates for imbalances in serotonin (an important brain chemical for mood, fine and gross motor skills, and calmness), as well additional markers that can indicate toxic stress in the brain and nervous system such as Quinolinic Acid. High Quinolinic Acid is suggestive of toxic stress in the brain and is important to evaluate before implementing certain supplements particularly L-Tryptophan which is commonly used to help with sleep.

    8. Evaluates for two specific chemicals related to folate metabolism. Folate is part of the methylation cycle that supports the inner workings of the cells related to DNA function.

    9. Evaluates for various nutritional markers such as vitamin B6, B5, vitamin C, CoQ10, as well as N-Acetyl-Cysteine which is necessary for the production of glutathione.

    10. Evaluates for glutathione production problems. Glutathione is the most powerful antioxidant in our cells and is often deficient in autism. The Organic Acid Test evaluates for cellular markers related to this important antioxidant.
