Component-resolved diagnostic cannot replace oral challenge for peanut allergy

IgE antibodies to Ara h 2 distinguish peanut allergy from asymptomatic peanut sensitization

Natural history of peanut allergy: strong association between high peanut-specific IgE and reaction severity

Ara h 2 sIgE test is more accurate than whole peanut sIgE to distinguish peanut allergy from peanut tolerance

Heavy metal and peanut allergy

Higher sensitivity in peanut allergy is associated with increasing age, sIgE, and eczema

SPT < 7mm and sIgE < 2kU/L identify children likely to tolerate peanut (only 5% likelihood of failing oral challenge)
