I tested high for the candida antibody IgA: 21 (HIGH) Reference: 0-9. IgE, and IgG were normal. Is this something I should begin to address or should I do more testing? Also, is blood testing for candida the gold standard, or do I need stool and/or saliva as well? This is the only positive I have turned up in my search for my CFS symptoms. The other minor positives were compound heterozygous MTHFR, and slightly elevated kryptoprolles. Other than that Candida is the first big positive I have come across.
