**45 minute lab consult included 

This lab will help you assess how well your digestive system is functioning as well as where your vitamin levels are at. With over 75 markers tested, the organic acids test can help you get to the root cause of microbial imbalances like yeast (candida) and bacterial overgrowth that can cause disruptive symptoms like gas, bloating, constipation and fatigue. 

Collection Method: Urine

Lab Description

“The Organic Acids Test (OAT) offers a comprehensive metabolic snapshot of a patient’s overall health with 76 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.” - Great Plains Laboratory
