Allergy Tests: When It’s Needed and When It’s Not

Have you ever wondered whether your child really needs an allergy test? Or have you been tempted by those flashy direct-to-consumer kits, this conversation is a must-listen. Let’s tackle the rise of at-home “food sensitivity” tests, the difference between IgE and IgG, and why a detailed history matters more than any panel of results. 

In this episode, I’m joined once again by pediatric allergist Dr. Dave Stukus to break down what parents really need to know about allergy testing. From food allergies to seasonal sniffles, we dive into when testing is actually helpful—and when it leads to confusion, false positives, and unnecessary food restrictions. 

We discuss: 

• Why most at-home food sensitivity tests are misleading—and what to do instead

• When allergy testing is truly helpful (and when it backfires)

• How to tell the difference between food allergies, intolerances, and sensitivities
