"The key to the diagnosis of these disorders is the suspicion of these disorders."

— Dr. Luis Murguia Favela

Immune dysregulation isn’t just about infections—autoimmunity, inflammation, and even malignancy can be clues that something deeper is at play. With over 500 known inborn errors of immunity, allergists are increasingly on the front lines of identifying these conditions. But when should we suspect immune dysregulation...

“Most penicillin allergy labels are not indicative of any meaningful penicillin allergic reaction, and the vast majority can be de-labelled with direct oral challenges of amoxicillin."  — Dr. Kimberly Blumenthal

Penicillin allergy is one of the most commonly reported drug allergies—but here’s the twist: most people who carry this label aren’t actually allergic. So how did we get here, and what can be done to fix it?

On this epis...

"We use thresholds every day without even thinking about it. When we do a food challenge in our office, whether we know it or not, we're relying on the fact that there is a threshold for every patient. Some are going to be on the first dose, some are going to be at the last. And that's just part of what a threshold is." 

– Dr. Doug Mack

Food allergies aren’t one-size-fits-all, but we don’t talk enough about thresh...

For many, pets are like family, which makes pet allergies a particularly sensitive issue. On this episode, ...
