Think diagnosing food allergies is as simple as running a test? Think again. Food allergy testing is a maze of gray areas, false positives, and, hopefully, a clear food allergy diagnosis.
Navigating food allergy testing can feel overwhelming, with skin pricks, blood tests, and conflicting advice. How do you determine which tests are truly useful? How can you avoid unnecessary dietary restrictions from false results?
In this episode, Dr. David Stukus, a board-certified allergist and immunologist, joins Dr. Gupta and Kortney to demystify the science of food allergy testing. From the importance of patient history to the latest diagnostic tools, Dr. Stukus provides clear guidance to help you make informed decisions while navigating food allergy testing.
What we cover in our episode about food allergy testing- The Crucial Role of History in Food Allergy Diagnosis: Dr. Stukus highlights why understanding a patient’s reaction history (symptoms, timing, and context) is critical for guiding effective testing decisions.
- Choosing the Right Tests: We break down skin prick testing, blood tests like IgE and component testing, and innovations like epitope mapping. Dr. Stukus explains why IgG testing is untrustworthy and emphasizes oral food challenges as the gold standard for diagnosis.
- False Positives and Negatives: Learn why expert interpretation of test results is crucial and how overtesting can lead to unnecessary restrictions and confusion.
- When to See an Allergist: Practical advice on when to consult a specialist and what to expect during your visit for evidence-based care.
