ALEX test or ALEX² test (Allergy Explorer) — is a modern molecular allergy test performed on a blood sample that allows for the detection of sensitization to 295 allergens simultaneously.
What does the ALEX test determine?
- Total IgE level — immunoglobulin E, responsible for allergic reactions.
-
Specific IgE to:
- Molecular components of allergens (e.g., individual proteins in pollen, foods, etc.),
- Whole extracts of allergens (e.g., birch pollen, milk, dust mites, etc.).
Advantages of the ALEX² test:
- Minimum blood (only a few microliters),
- One test instead of dozens of separate analyses,
- Detection of cross-allergy (e.g., between pollen and fruits),
- Can be done even while taking antihistamines,
- Painless (does not cause an allergic reaction, unlike skin tests),
- Creation of an allergy profile or patient passport.
What is it needed for?
- Diagnosis of respiratory, food, contact allergies,
- Understanding which specific molecules cause allergies (this is important for deciding whether to conduct allergen-specific immunotherapy),
- Detection of hidden or non-obvious allergens.
