Component analysis of milk-allergic children with α-Gal. Patients with α-Gal–specific IgE who were positive for specific IgE to milk (n = 34) were tested for milk components, including α-lactalbumin, β-lactoglobulin, and casein-specific IgE. Interestingly, there does not appear to be any reactivity to the milk components (α-lactalbumin, β-lactoglobulin, and casein), suggesting that there is no α-Gal in these immunoassays. Similar results are present for boiled milk and goat’s milk.
