Candida is.a yeast in the gut. It's often commensal, or "friendly" - all of us likely have some of it in our bodies, but with the right fuel and the right conditions, Candida can become overgrown, "pathogenic" and cause a lot of problems. There is a whole lot of science that can be learned about Candida and other fungal things, and it's one of the most common things I find on lab testing, and I've found that it can drive a lot of issues, including autoimmunity and many of the underlying mechanisms associated with autoimmune conditions - leaky gut and permeability, Th2/Th17 codominance, inflammation, histamine, and the associated symptoms like brain fog, fatigue, anxiety, gut issues, thyroid issues, etc. More importantly, by addressing yeast and other fungal issues clinically, I see people improve, often drastically. So - - how do you find it?
There are a lot of ways to detect Candida on lab testing, and it kind of depends on what you are looking for......
Are you measuring Organic Acids that are often produced by Candida and other yeasts? This is actually my personal favorite.... #3 (Oxoglutaric) and #7 (Arabinose) on Mosaic's OAT test are yeast markers, and there are others on that test as well!
Or, are you looking for Candida in the gut using a stool sample? I like GI Map the best, but there are other methodologies that can detect it differently....
Or - are you measuring immune reactivity? If so, is it IgG, IgE, IgM, or IgA?
Is that in the blood, or is it in the saliva to measure the mucosal response (secretory IgA)?
The point is - sometimes you have to look in a different way or in a different place to find what is driving your symptoms. The best test is the one that shows us the right levers we need to pull! It takes YEARS to learn the science and the art of lab testing and to learn from experience, trust me, I know - but DO YOU (or your practitioner!) know which tests to run, what they are showing you, how to interpret the results, how to address them, and what that means to YOU and YOUR health puzzle?
