Understanding Biomarkers in Asthma and Allergic Diseases

In this episode, we explore the growing role of biomarkers in asthma and allergic diseases and why they are becoming essential in modern diagnosis, phenotyping, monitoring, and personalised treatment. We discuss key asthma biomarkers and allergy biomarkers, including blood eosinophils, FeNO (fractional exhaled nitric oxide), total and specific IgE, and their relevance in identifying type 2 inflammation, allergic asthma, severe asthma, and other allergic conditions.This episode looks at how biomarkers in asthma can help support accurate diagnosis, guide targeted biologic therapy, improve asthma management, and advance precision medicine in allergy and respiratory care. We also consider the wider application of biomarkers in allergic rhinitis, eczema, food allergy, and eosinophilic disease, highlighting their importance in shaping more individualised and effective treatment strategies.Whether you are a paediatrician, allergist, respiratory clinician, trainee, healthcare professional, researcher, or someone interested in the latest advances in asthma care and allergic disease management, this episode provides a practical and accessible overview of how biomarkers are transforming clinical decision-making in asthma and allergy medicine.Sources:Agrawal, N. and Kraft, M.
