Skin Prick Test to Egg White Provides Additional Diagnostic Utility to Serum Egg White-Specific IgE Antibody Concentration in Children.

The article discusses research being done on the use of skin-prick tests (SPT) to determine children with low egg white-specific immunoglobulin E (IgE) levels. It references a study by A. K. Knight and colleagues published in a 2006 issue of the "Journal of Allergy & Clinical Immunology." This study was a retrospective analysis of oral egg challenges in children with egg allergy and low egg white-specific IgE antibody levels. Key findings found that egg-allergic children with low egg-white-specific IgE levels, a small SPT response and a low egg/histamine index are more likely to pass oral food challenges.
