Allergen component testing is a new technology that pinpoints sensitization to
specific allergen components (proteins) of a substance that may be causing a
Allergen Component Testing helps the physician:
- Identify primary, species-specific, allergen components (proteins) that cause
allergic sensitization in patients
- Assess the patient’s risk of an allergic reaction to those proteins found in certain foods
- Provide clarity regarding the patient’s risk of allergic reaction to ease fears and help target effective management: ensure relevant dietary modifications
and medications, determine appropriateness of a patient for oral food challenge testing
The ImmunoCAP Allergen Component tests are a group of tests, carefully selected to evaluate peanut
IgE sensitization patterns at the protein level. This level of detail allows the clinician to
assess the patient’s risk of allergic reaction and to differentiate between symptoms caused by
cross-reactive proteins verses primary, species-specific proteins.

ImmunoCAP Component Tests are commercially available for peanuts, cow’s milk and hen’s egg.
Additional tests to common allergens are currently being researched and developed through the
Phadia Immunology Reference Laboratory Center for Innovation.
