Kido J, et al. - Researchers investigated if skin prick test (SPT) and blood-specific IgE concentrations could serve as valuable diagnostic tools based on the outcome of the oral food challenges (OFCs) for heated and raw hen egg among 103 children with suspected hen egg allergy (HEA; median age 23 months, range 10–155; 72 boys, 31 girls). They found that as diagnostic tools for HEA, the SPT and blood-specific IgE can be used. They also noted that since there was no significant difference in the values of SPT and specific IgE between children with and without raw egg allergy, it is important that children without HEW allergy undergo the provocation test for raw hen egg white.
