The Organic Acids Test (OAT) provides an accurate metabolic snapshot of what is going on in the body. Besides offering a most complete evaluation of intestinal yeast and bacteria, it also provides information on important neurotransmitters, nutritional markers, glutathione status, oxalate metabolism and much more.

Abnormally high levels of  microorganisms can cause or worsen behaviour 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 may 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.

The test includes a  profile of 73 organic acids (including 20 microbial organic acids) that can be useful for discovering underlying causes of chronic illness. 

The OAT assists in evaluating:

  • Krebs cycle abnormalities
  • Neurotransmitter levels
  • Nutritional deficiencies
  • Antioxidant  deficiencies
  • Yeast and Clostridia overgrowth
  • Fatty Acid Metabolism
  • Oxalate levels



  • Toxic organic chemical profile
  • IgG Food Allergy + Candida
