What is it?

The Alex² test is the largest allergen panel on the market, used to obtain an accurate and complete picture of a patient’s sensitisations, including potential cross-reactions (CCD).

It allows simultaneous analysis of up to 300 allergens; 117 allergen extracts and 178 molecular allergens, in addition to 60 allergens unique to the Alex² test.

• Molecular extracts: the test uses allergen extracts when molecular allergens are not well characterised or are redundant due to a high degree of cross-reactivity.
• Molecular allergens: used when allergen extracts are described as unstable. A more accurate risk assessment is achieved.

The combination of both ensures an accurate profile of the patient’s sensitisation status.

What technique do we use?

It is a multiplex test, meaning that from a single blood sample it simultaneously detects IgE to multiple allergen extracts and molecular allergens in a single assay.

Multiplex tests provide the most complete and reliable picture possible of a patient’s sensitization profile, whereas singleplex tests can leave gaps and empty spaces that make the picture incomplete.

Benefits of the Alex² test

• Avoids the need for invasive skin testing.
• No need to stop anti-allergy medication.
• Complete picture of the patient’s sensitization status.
• Prevents the occurrence of cross-reactions (CCD).
• Covers almost 100% of globally relevant allergens in a single assay.
• Molecular allergens allow specific IgE to be determined against a multitude of allergens.

Who is it for?

• Patients with rhinitis, conjunctivitis and/or asthma, atopic dermatitis, urticaria.
• People allergic to food, inhalants (pollen, mites, epithelia, fungi), latex, hymenoptera venom.
• People who have experienced anaphylaxis(s) and do not know the cause.
