Alex2 test: allergen diagnosis

250,00 €

The largest allergy panel on the market that analyses up to 300 allergens (non-invasive). Get an accurate and complete picture of your body’s allergic sensitizations, including possible cross-reactions (CCD).

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?

The Alex2 test is especially indicated to determine specific sensitizations in patients with suspected allergies, to improve the diagnosis of these patients and to avoid diagnostic and therapeutic errors related to allergies.
Especially indicated 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.

Results

The results report includes a summary of detectable sensitivities to:
Pollens: trees, grasses and weeds.
Mites: from house dust and storage.
Plant-based foods: legumes, cereals, spices, fruits, vegetables, nuts and seeds.
Foods of animal origin: milk, eggs, fish, shellfish and meat.
Insects and poisons: ant, bee, wasp and cockroach.
Microorganisms: spores, yeasts, fungi and molds.
Epithelia: pets and farm animals.
Others: latex, ficus, CCD and parasites.

Sensitization of increasing degree by allergen groups is also specified, from negative or doubtful sensitivity to very high IgE detection level.

In addition, a summary of the interpretation of the results is added with specific comments and recommendations.
