ALEX2

What is ALEX2?

  • The Allergy Explorer2 (ALEX2) is an allergy test developed by MacroArray Diagnostics GmbH that can assist physicians in diagnosing allergy.
  • It is a state-of-the-art multiplex Enzyme-Linked Immunosorbent Assay (ELISA) test based on proven immunoassay chemistry and detection methods.
  • It is an extremely comprehensive allergy test, testing for 295 molecular allergens simultaneously.
  • It is a next generation quantitative in-vitro multiplex diagnostic test that measures allergen specific IgE (sIgE).
  • It is also a semi-quantitative in-vitro diagnostic test for total IgE (tIgE) in human serum or plasma.
  • The ALEX 2 assay protocol integrates a powerful Cross-reactive Carbohydrate Determinants (CCDs) inhibitor during serum incubation, which will clear up your specific IgE results.
  • This reduces the interpretative burden for physicians of CCD positive patients and increases the specificity of test results.

ALEX2 offers many advantages over other allergy tests:

  • Comprehensiveness
    • It can help give a complete picture of allergic reactions to pollen, mites, animals, insects, mould, yeasts, food, latex- everything except drugs.
    • Tests for 295 allergens simultaneously
    • Simultaneous measurement of total and specific IgE
    • Near-complete allergen panel, individually optimised
  • Speed
    • Tests are conducted entirely in Hong Kong
    • Results within 7 working days
    • Extract blood sample ’n’ go
  • Safety
    • In-vitro: no risk of adverse reaction
    • Requires less than 2ml of blood
  • Convenience
    • Multiplex test with on-demand panel composition
    • Integrated CCD inhibition
    • Reduces interpretive burden for physicians
    • Does not require patients to sit and wait in your waiting room or surgery

FAQs

  • What do I tell my patient if the panel comes back negative for all allergens?
    • Our patient did not display an IgE-mediated allergic reaction to the 295 allergens. However, this does not necessarily mean your patient has no allergies.
  • What types of blood are acceptable?
    • Any, including capillary tube blood sampling
  • How much blood is needed?
    • 2 ml
  • Does ALEX2 test for drug allergies?
    • No
