Decoding Component-Resolved Diagnostics: A New Era in Allergy Testing
Component-Resolved Diagnostics (CRD) is transforming the way we diagnose and manage food and aeroallergy. In this episode, we break down what CRD really is, how molecular allergy testing works, and how it improves clinical decision-making beyond traditional IgE and skin prick testing.
We explore:
- ✅ What CRD is and when to use it
- ✅ Benefits of molecular allergen testing over extract-based testing
- ✅ Clinical interpretation of key allergen components (Ara h 2, Cor a 9, Fel d 1 and more)
- ✅ Risk stratification for anaphylaxis using CRD
- ✅ Practical pros, limitations, and cost considerations
- ✅ When CRD really changes patient outcomes
Whether you are a paediatrician, allergist, GP with a specialist interest, immunology trainee, dietitian, nurse specialist, medical student, or healthcare professional, this episode offers practical, evidence-based insights you can apply in clinical practice tomorrow.
🔬 Precision medicine starts with precision allergy testing — let’s decode CRD together.
