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.

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
