Which leads me to this post!
Today we saw Luke's allergist for his annual visit. We saw her several times last summer and fall for two different in office food challenges (IOFCs) for peanuts and eggs. Eggs he originally passed, but then went on to have major reactions to baked in eggs at home. Peanuts he failed after the second dose in office. She decided then that we would no longer base IOFCs on RAST (blood test) results because his RAST scores don't appear to match with his reaction. His RAST for peanuts last summer was actually negative, and the RAST for egg was extremely low. We decided to go for a skin prick test (SPT) today to see if an IOFC for either peanuts or egg, or both, would be in our future. The picture below shows his back, with the SPT in progress, about halfway through the test. She also tested for a few tree nuts.
1 - Positive control 2 - Negative control A - Almonds C - Cashews P - Peanuts W - Walnuts E - Egg
I will be very nervous about introducing tree nuts to him, but I am excited that this will open up some new food choices for our family.
One more picture of his egg wheal. She considers this a major reaction. The worst part is that this makes her feel that he will probably not outgrow his egg allergy. This of course made me extremely sad.
