My son was tested skin positive at 18m then rast positive. Fast forward to age 5, we have avoided peanuts, and manufactured in products, tell restaurants when we come in. He has never had a known reaction. He was rast tested again peanut came back "off the charts" high, he has a history of environmental allergies so we were nervous of a false positive and had him component tested. We were told his component test came back high and we are to change nothing in terms of avoiding peanuts, but I would like to better understand what the numbers mean.
The component test reads as follows:
Ara h 2 (f423) 60.2 H <0.10 kU/L
Ara h 1 (f422) 88.8 H "
Ara h 3 (f424) 0.54 H "
Ara h 9 (f427) <0.10 "
Ara h 8 (f352) <0.10 "
