I think a CDSA for Candida will mostly return false negatives. My CDSA didn't even detect Candida. My BioScreen stool analysis measured Candida, but within the reference range. I don't think any stool analysis will show up a Candida overgrowth unless it is in the large bowel. I think most Candida overgrowth is in the small bowel, and this will not show up well on stool analysis. IMO stool analysis for Candida is in most cases useless.
