NEW: Adult Food Allergy in Primary Care: Practical Diagnosis, Pitfalls, and Management Strategies

Nearly 11% of U.S. adults meet criteria for a convincing food allergy, yet most clinicians underestimate both the prevalence and unique challenges of adult-onset disease. This episode addresses the frequent misdiagnosis and clinical uncertainty surrounding new symptoms in adults by highlighting epidemiology, risk factors for delayed and severe reactions, high-yield history-taking, diagnostic pitfalls, and guideline-supported use of specific IgE and component-resolved diagnostics. Listeners will learn to distinguish allergy from intolerance, understand psychosocial burdens, apply evidence-based testing algorithms, and recognize when to refer for oral food challenge or advanced management. With practical insights into differential diagnosis, best practices for test interpretation, and strategies to streamline care in busy settings, this episode equips providers to close the adult allergy diagnosis gap and optimize patient safety.
