About Allergy Testing Testing
Traditional allergy testing often fails to provide the diagnostic clarity needed for effective management. Our Component-Resolved Diagnostics identify precisely which protein components trigger your immune response. This is critical for distinguishing mild oral allergy syndrome from severe anaphylaxis risk requiring adrenaline auto-injector prescription.
The ALEX2 Multiplex simultaneously screens 295 allergen components from a single blood sample: respiratory allergens (pollens, moulds, dust mites, pet danders), food allergens (milk proteins, eggs, nuts, shellfish), insect venoms, and latex. Results in kUA/L enable monitoring of immunotherapy efficacy or natural tolerance development.
