Organic acids testing looks at molecules that went through some metabolic pathway(s) and then get excreted in urine. Many of the metabolites measured by an organic acids test are reliably correlated to some of the body’s oxidative stress. What is that you are seeking to know with this test?
These markers can be useful in a few circumstances but it requires a specific reason for investigating them and the possibility, at least in theory, to affect them before retesting their levels. ‘Test re-test’ is a key to evidence based medicine. If these criteria aren’t met, you probably don’t need to worry about them.
