Unfortunately these blood tests are only about 40% accurate. They show both
false positives and false negatives. You could be allergic to foods that
don't show up on the test, and positives on the test ONLY mean there's an
antibody, it DOESN'T necessarily mean the food is a problem. We all have
intestinal permeability (leaky gut) to some degree, it's problem only when
the gut gets too permeable. The only way you can accurately find out which
foods are a problem is to run a systematic elimination diet. I'm glad I did
this, because TONS of the foods that showed up positive on the antibody test
were great foods for me, and some highly allergic foods didn't show up on the
test. Use the blood tests as one small piece of information only.
