What is Molecular Allergy Diagnosis?
Molecular or component-based allergy diagnosis is a modern method of detecting allergies by identifying sensitization to specific protein allergens. Unlike traditional testing with allergen extracts, this method determines exactly which components trigger an immune response, helping distinguish true allergy from cross-reactivity.
Molecular diagnosis helps:
- Identify the true allergy source (single or multiple allergens);
- Select the most effective allergen-specific immunotherapy (ASIT).
House Dust Mite Allergy and the Role of rDer p 23
House dust mite allergy is one of the most common causes of allergic rhinitis, asthma, and skin reactions. Mites like Dermatophagoides pteronyssinus live in mattresses, pillows, blankets, and carpets, feeding on dead human skin cells. Their waste products contain protein allergens that can trigger allergic reactions.
One of the key allergens of house dust mites is rDer p 23 IgE, which plays a significant role in allergy development and is detected in a large percentage of sensitized patients.
Symptoms of rDer p 23 Allergy:
- Nasal congestion or runny nose
- Sneezing
- Watery, red, itchy eyes, eyelid swelling
- Skin rashes, redness, itching
- Coughing, wheezing, shortness of breath (in severe cases – asthma symptoms)
Why is rDer p 23 IgE Testing Important?
- Helps determine true house dust mite allergy.
- Prevents unnecessary lifestyle restrictions.
- Allows doctors to select the most effective therapy, including ASIT.
If you experience allergy symptoms, consult an allergist for proper diagnosis and treatment planning
