Extension of food allergen specific IgE ranges from the ImmunoCAP to the IMMULITE systems

These data indicate that specific IgE levels to egg white, milk, and peanut measured by the IMMULITE and ImmunoCAP systems are highly correlated and that differences between the systems are circumscribed and modest (IMMULITE was a mean of 2- to 5-fold higher than ImmunoCAP).
