Living With Food Allergies

Food Allergy Testing - What You Need to Know

Kids With Food Allergies (KFA), a division of the Asthma and Allergy Foundation of America hosted a free educational webinar, "Diagnostic Testing for Food Allergies: What You Need to Know" on April 16, 2014. It featured pediatric allergist David Stukus, MD.

Dr. Stukus reviewed:

  • Definitions of allergy, intolerance, sensitization, antibodies
  • What is an IgE mediated food allergy
  • Symptoms of food allergy
  • The different types of food allergy tests and what they mean
  • Skin testing limitations
  • Blood specific IgE testing (ranges, classes, commercial panels)
  • False positives and predictive values
  • Do-it-yourself allergy kits and other controversial tests
  • Oral food challenges
  • Component IgE testing
  • Patch testing for delayed reactions
  • What about IgG?
  • Eczema, eosinophilic esophagitis and other related allergic diseases


An attendee gave this review as the most valuable part of the webinar:

“I liked how you had a doctor that specialized in pediatric allergies because he did a great job of explaining terminology, tests and results, and misconceptions.”
