Is it a trap, or is it reasonable caution? Â My daughter's test results were huge for shellfish as big as her life-threatening dairy allergy, yet her only exposure would have been in BM or in a small amount of oyster sauce. Â Our allergist tested for the more common allergens, and the dangerous ones. Â Her first skin test was at 2. Â Our allergist asked that we avoid the Big Allergens for a time for two reasons: she had a severe, confirmed allergy already. Â Her numbers were sky high for an extremely dangerous allergen. Â He believed that this kind of kid is likely to add more allergies, and he was right. Â Wheat was never a problem until around 3yo, then it became a huge problem, a miserable one until she was retested at almost 5 and we figured out the connection after she improved after eliminating it. Â
   At 4, she tested positive for a huge array of foods, many more than at 2. This could have been in part from imperfect results.  I know in retrospect that almond should have shown up the first time, but it might not have been included in the "nut mix" in the first round.  Or these new results could have been from new allergies, which I also believe. Â
  At 6.5, the doc is wanting to do more food challenges.  Corn seems to be better now, so that's a "go" in small amounts.  Next is buckwheat and rice. We have the green light to do a home challenge for fish again.  Her tests were positive, and I halted the first challenge after she complained of tingly skin when we smeared some salmon on her forearm.  Peanuts, a mild allergen on her test, he wants to challenge in office.  Shellfish he is still uncomfortable challenging, even in a clinical setting.
   I have a bazillion allergies as well, and my skin test numbers match very well with my experiences for the most part.  Reactions for each food is so different, I can tell you with a fair degree of accuracy what it was I accidently ingested just by the symptoms.  Nothing but peanuts cause my eyelids to feel fat.  Soy does something weird to my jaw: some odd, indescribable tingling sensation in some glands there.  Rice feels like a really crappy sugar rush.  Corn is a fat tongue.  Oats cause confusion and elevated heart rate.  That one's the worst.  And even though "the numbers" for sesame and hazelnuts are the same, I cannot have even small amounts of the hazelnuts.  That one is a bit tricky, I admit.Â
   I do not feel we were "entrapped".  I had seen my daughter struggle with a scary dairy allergy, and have been close to grabbing the EpiPen Jr. twice for accidental ingestion.  I am glad we tested the big ones.  I know challenges are the real test, but I am totally at ease with avoiding shellfish, even though it's possible that her shellfish allergy is a false positive.  I trust in my allergist's caution, it mirrors my own.  Now that he wants us to start challenges again, I trust him there, too.Â
   I think it was a good idea to test in our case.  I understand the other viewpoint.  I understand the vagaries of testing.  I understand allergies because I struggle with them, too.  I do think parents can relax somewhat and advise that regularly.  I have relaxed a lot in the last 6 years.  But testing?  I have no regrets.
