Yeast & Bacteria - Organic Acid Test

The Organic Acids Test (OAT) offers a comprehensive metabolic snapshot of a patient’s overall health with over 70 markers. It 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 in their urine. The cause of these high levels could include oral antibiotic use, high sugar diets, immune deficiencies, acquired infections, as well as genetic factors.

Our Organic Acids Test also includes markers for vitamin and mineral levels, oxidative stress, neurotransmitter levels, and is the only OAT to include markers for oxalates, which are highly correlated with many chronic illnesses.

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 Organic Acids Test provides an accurate snapshot of what is happening inside the body.

It provides information on yeast, bacteria and other nutritional markers.  The test includes 74 urinary metabolic markers useful in discovering underlying causes of chronic illness.

OAT Testing assists in evaluating

  • Krebs cycle
  • Neurotransmitter Levels
  • Nutritional Deficiencies
  • Antioxidant deficiencies
  • Yeast  overgrowth
  • Fatty Acid Metabolism

Select disorders which may benefit from this test

  • Autism
  • Neurological disorders
  • Mental Health disorders
  • Chronic gastro-intestianl disorders



All that is required to test for organic acids is a simple urine test. The sample
will be taken by your healthcare professional and sent to the laboratory for analysis.

Avoid apples, grapes, pears, and cranberries as well as their juices or products 48 hours before collection.
Avoid arabinogalactan, echinacea, reishi mushrooms, and ribose supplements for 48 hours before collection.

Females, please do not collect samples during menstrual cycle.

Generally speaking test results will come back within 3 to 4 weeks

Test results are sent back to your practitioner who will then schedule a follow-up visit with you to go over the results and prescribe a protocol based on results.

Many health care providers will cover testing, although it is best to confirm with them prior to testing.
