It sounds like you had an ELISA or similar test. I had one done and I didn't
find mine to be a very good predictor of which foods would bother me. There
were some correlations--it did find a very high overall sensitivity level
for me, vs. much lower for my father, which matches our experience, and it
did find sensitivity to some of the foods that cause me symptoms, but some
foods that scored highly cause no noticeable symptoms and some that cause me
lots of symptoms didn't score very highly. Other people here have also noted
that in the past. So I think ELISA may be only suggestive rather than
prescriptive.
