The Truth About Broad Food Allergy Panels: Why Less Is More
Feeling Tempted by Food Allergy Panels? Read This First.
Pediatricians, don’t give in to the temptation. Patients, please don’t either. Ordering broad food allergy panels might seem like a shortcut to answers, but it often leads to confusion, unnecessary worry, and even harm.
What’s the Real Problem With Broad Food Allergy Panels?
What Do Food Allergy Tests Actually Mean?
Let’s clear up some common misconceptions:
- Do these tests show allergy severity? Nope.
- Does a positive test mean you’re allergic? Nope.
- Does a negative test mean you’re in the clear? Not necessarily.
- Do they detect food sensitivities? No. In fact, no test reliably detects sensitivities, no matter what Google or marketers claim. Don’t be fooled by hype—stick with real evidence.
- Do they diagnose celiac disease? Nope.
So, what’s the point? Food allergy tests only estimate the likelihood that you’ll react to a specific food if exposed. They do not predict how severe a reaction could be.
Why Are Broad Panels a Bad Idea?
The Risk of False Positives
About half of all positive results on broad panels are false positives. If you end up with a list of “allergies” from a broad panel, but your risk factors are low, what happens next? Often, the provider who ordered the test isn’t sure how to interpret the results and refers you to a specialist—who will likely tell you the panel shouldn’t have been ordered in the first place.
The Right Approach: Targeted Testing With Context
Why History and Context Matter
Effective food allergy testing should always be guided by a patient’s history. Results need to be interpreted alongside other allergies (like pollen, shellfish, or latex) because cross-reactions are common. Sometimes, additional tests are needed to make sense of the full picture. Unless a provider understands all these interactions, important details can be missed.
The Bottom Line
Work With a Specialist
If you’re not working with a specialist in food allergies, you might not know what you don’t know. The result? Ineffective testing, unnecessary food restrictions, and more confusion than answers.
If you have concerns about food allergies, consult with an expert who can help you get the answers you need—without the risks of over-testing.
