Organic Acids Test OAT + Amino Acids Mosaic Diagnostics

Mosaic Diagnostics  formerly The Great Plains Laboratory, Inc. is now offering the OAT and Amino Acids Urine Test as a combination.

The Organic Acids Test (OAT) provides a metabolic “snapshot” based on the products the body discards through the urine. These small, discarded organic acid molecules are byproducts of human cellular activity, the digestion of foods, and the metabolism of gastrointestinal flora. At certain levels, organic acids in urine may be indicators of toxicity or “markers” of the function of metabolic pathways. Levels of yeast or gastrointestinal bacteria metabolites are compared to normal levels of human metabolites, providing an assessment of yeast and bacterial activity.
The new and improved OAT has increased the number of tested compounds to 74 (including Creatinine) and two new ratios have been added. The new compounds detected may result from variations in vitamin and hormone metabolism, energy level, intestinal wall integrity, neurotransmission, and muscle function. Urine test you collect at home and send to the lab. Doctors order provided. You receive the results.

The Amino Acids Urine Test offers important clinical data on metabolic, nutritional, and neurological disorders. The test analyzes 40 amino acids and provides a detailed explanation of the possible causes and consequences of detected abnormalities, along with nutritional information. Amino acid imbalances are frequently underlying factors in disorders such as ADD, depression, Tourette syndrome, tic disorder, OCD, seizures and others.

Clinical Indications for OAT

Included along with this comprehensive profile is:

1.) The Doctor’s Order required to access testing.
2.) The kit/shipping supplies to collect your samples in the privacy of your home and return to the lab.

There are no additional fees to access this testing, you are sent the results.

Add-ons total:



The Organic Acids Test (OAT) offers the most complete and accurate evaluation of intestinal yeast and bacteria. These factors are of critical importance in neurological,gastrointestinal, and movement disorders. Abnormal toxic metabolites of these
microorganisms can cause or worsen behavior disorders, hyperactivity, movement disorders, affect energy levels and immune function. Yeast can attach to the intestinal wall causing “leaky gut” syndrome, which can cause or magnify
food allergies, impede absorption of vitamins and minerals, and cause intestinal disorders. Many people with chronic illness, allergic conditions, and neurological disorders often have one or more abnormal levels of organic acids in their system.
Factors which can cause or affect the intestinal yeast overgrowth include oral antibiotic use, excessive sugars in the diet, selective or combined immune deficiencies, genetic and other factors.
