How Accurate Are Allergy Tests? Unpacking IgE-Mediated Food Allergy Diagnostics

How accurate are the tests we rely on to diagnose IgE-mediated food allergy? In this episode, we explore the science behind skin prick testing, serum-specific IgE, and oral food challenges, examining their sensitivity, specificity, predictive values, and real-world limitations.Join us as we separate evidence from assumption, discussing false positives, cross-reactivity, and component-resolved diagnostics—and how to interpret results in the context of clinical history.Whether you’re a clinician, allergy trainee, or researcher, this episode will help you navigate the complex landscape of allergy diagnostics with clarity and confidence.Source:Riggioni, C., Ricci, C., Moya, B., Wong, D., van Goor, E., Bartha, I., Buyuktiryaki, B., Giovannini, M., Jayasinghe, S., Jaumdally, H., Marques-Mejias, A., Piletta-Zanin, A., Berbenyuk, A., Andreeva, M., Levina, D., Iakovleva, E., Roberts, G., Chu, D., Peters, R., du Toit, G., Skypala, I. and Santos, A.F.
