Prevalence of pollen food allergy syndrome (PFAS) varies by geographic location and is between 2% and 70% based on the study. Pollen food allergy syndrome can presents as a spectrum of symptoms ranging from isolated oropharyngeal symptoms to anaphylactic shock. Treatment of PFAS needs to factor in risk of severe reaction, quality of life, cost, and patient preference. Risk assessment will be able to be more individualized as additional component testing becomes available.
