I'd be very interested in having OAT testing done if I really felt it was genuine. The problem is that there's a lot of scientific jargon thrown around and it feels quite like the 23andMe bandwagon that everyone jumped on a few years ago. But quite a bit turned out to be hogwash. This is from Great Plains Laboratory: "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 Microbial Organic Acids Test (MOAT) is ideal for follow-up to the OAT and is often recommended by practitioners looking for a specific abnormality, to monitor certain microbial imbalances, or to assess treatment efficacy." Doesn't this look fantastic? We should all get this done! Right now! Why don't our mainstream doctors offer us this test? But the British NHS, (National Health Service), does do a similar one, and I'm certain Organic Acids are tested the world over, but not like this, but for: "Disorders of organic acid metabolism [which] comprise a diverse group of diseases whose biochemistry involves several areas of intermediary metabolism. These include metabolic pathways associated with amino acid metabolism, fatty acid metabolism and ketogenesis, and of pyruvate and carbohydrate metabolism including the TCA cycle". Source: NHS, UK It comes down to this: Is this a test that's been taken from the mainstream and utilised for fringe patients in a credible way for treatment? Or is it another bandwagon-cashcow?
