What is an OATS test?



On a few of the message boards I frequent, I heard about something called an “OAT test” which I had no clue about. It made me think of oatmeal and I immediately imagined a canister of Quaker oats. Sidebar: I miss oatmeal. Its high in oxalates, even the gluten free kind.


OAT is most definitely not oatmeal. It stands for Organic Acid Test. Here’s the official info from Great Plains Lab:

Organic acids are chemical compounds excreted in the urine of mammals that are products of metabolism. Metabolism is the sum of chemical reactions in living beings by which the body builds new molecules and breaks down molecules to eliminate waste products and produce energy. Organic acids are organic compounds that are acidic. Organic acids are substances in which carbon and hydrogen are always present but which may also contain the elements of oxygen, nitrogen, sulfur, and phosphorus as well.


The Organic Acid Test is a comprehensive assessment for a wide variety of biomarkers related to yeast (candida) and bacteria toxicity – specifically clostridia bacteria. It also evaluates oxalate toxicity, as well as mitochondria function, and various markers for vitamin and neurotransmitter problems.


So…what information can be learned?



Great Plains Lab answers:

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.


When I went for my latest doctors visit, I asked about the test but the office is not contracted with the lab and does not offer this OAT. I went home to mull over my options and learn more to see if the test was something that might shed light on my many issues.

Natural News has a good article about it, read it all here! 

I’m picking out some key info:

The organic acids test is a simple urine test that looks at biomarkers from various metabolic pathways. These biomarkers give an overview of several major systems in the body and an analysis of nutritional deficiencies in the body

There are many health conditions that could be remedied or greatly improved through the specific information the organic acids test provides. For example, many individuals are unable to metabolize folate effectively due to a condition called 5,10-methylenetetrahydrofolate reductase (MTHFR) deficiency. The organic acid test can look at methylation rates and help understand if the individual is producing folate and other key B vitamin levels.

This test also can give a good clue as to what microbes are predominating the gut such as yeast, fungi, Clostridium or Giardia. They also look at glutathione synthesis levels and liver detoxification markers. Overall this test provides excellent information for a specific supplement protocol.




Conditions that benefit from this test:

Sleep abnormalities
Mood changes
Blood sugar dysregulation
Weight gain
Multiple chemical sensitivity
Bloating, gas and distention
Joint pain
Acid reflux
Autoimmune disorders
Accelerated aging



I spent a few weeks going back and forth about the test, would it help? What information would it provide that would improve my health? I was concerned about the fact I cannot seem to get rid of this candida. Also not processing oxalates is causing me distress. Knowing if there was a bigger picture I was missing would definitely be helpful. I have a lot of small things going on in my body, maybe together this means something that my own doctor has missed.

On Dr. Jocker’s website, you can buy the test and get your results along with supplement recommendations. I am all for doing everything online and avoiding another doctors visit and expensive co-pay. I ordered the test which is nothing more than a urine test, and mailed it back then waited.

After about two weeks, I got my results which I tried to analyze myself by searching the internet for key words and phrases. I was super high in some things and low in others but the biggest revelation was that the candida wasn’t as bad as I thought. When I spoke to the nutritionist, candida wasn’t what she was most concerned with. She recommended some supplements through Dr. Jockers, which I did buy. I think they are helping…I believe one of my biggest problems is leaky gut. Oxalates weren’t even an issue according to the test but by now I am only eat low oxalates foods.

Leaky gut is a whole other topic that can be explored for days. Briefly put, the junctions in the gut which should be tight like the knot in a shoelace, are wide and loose enabling food particles to slip through and wreck havoc in the body.

I am liking the GI Regulator I have less stomach troubles than I did before.

Plus the Proteo Enzymes:

This supplement is great for people with microbial overgrowth as the proteolytic enzymes help to metabolize the outer biofilms of the various microbes.  Often, people have trouble reducing microbial overgrowth because of these biofilms.  This supplement can be a huge game changer for someone trying to heal from digestive complaints. 

Since taking both, I have noticed less candida symptoms which is actually amazing.



I would recommend doing the OAT test via Dr. Jockers website. The supplement protocol was helpful, I think they are working for me which I am grateful for. The worst part of the test was waiting for the results, count on about two weeks before you hear anything. This detailed report will be hard to  understand so the breakdown with a specialist was very helpful.

Have you had this test? Did you learn anything from it?
