ALEX² Allergy Explorer Test for Patients with Hay Fever, Asthma, Hives or Food Reactions

What is ALEX² Allergy Explorer Test?

The ALEX² Allergy Explorer (Allergy Explorer 2) is an advanced blood test that screens for almost 300 allergens, including pollen, foods, animal dander, mites, moulds, venoms and more—including molecular components to clarify cross-reactivity patterns  .

Who can benefit?

Best suited for patients experiencing:

• Hay fever (seasonal allergic rhinitis)
• Asthma — especially if linked to allergies
• Chronic hives (urticaria)
• Suspected food allergy, especially in cases of severe or unexplained reactions
  It’s ideal when standard testing hasn’t pinpointed the trigger.

Why choose ALEX² Explorer Test?

1. Comprehensive screening
   Evaluates IgE antibodies to ~295 allergens in one test  .
2. Molecular precision
   Analyses allergen molecules to differentiate true sensitisation from cross-reactivity, critical for foods, pollens and more  .
3. Convenient sample
   Requires only a small blood sample—quick clinic draw or finger‑prick home kit; no need to stop antihistamines or steroids  .
4. Fast results
   Typically available in 5–7 working days  .
5. Supports treatment planning
   Helps in tailoring allergen avoidance, prescribing immunotherapy and guiding dietary advice  .
6. CE-certified & research-backed
   Proven reliable in clinical trials and widely used in precision allergy diagnostics  .

Who is it for?

• People whose symptoms persist despite standard treatments
• Those who are polysensitised (react to multiple pollen/food types)
• Patients needing clarity on molecular cross-reactivity (e.g., pollen–food syndrome)
• Individuals planning allergen immunotherapy, such as for grass pollen

What the Alex2 Allergy Explorer Test involves

1. Discuss your symptoms and history with your doctor.
2. Collect a blood sample (clinic draw or home kit).
3. Send your sample to the lab.
4. Receive a detailed PDF report within 5–7 days.
5. Review the results with your doctor for next steps.

Understanding your results

Your report will show:

• Sensitisation levels (IgE classes 0–4) for dozens of allergens.
• Molecular profiles, showing where sensitisation is genuine or due to cross-reactivity, helping tailor your treatment  .

Advantages for Specific Conditions

Condition	How ALEX² Helps
Hay fever	Identifies specific pollen triggers; supports immunotherapy decisions
Asthma	Pinpoints allergy-driven asthma triggers—even from dust mites
Hives	Detects hidden allergic sensitisation when skin testing isn’t possible
Food reactions	Highlights severe risks vs co‑reactivity (e.g., Bet v 1 & birch‑related foods)

Important things to remember

•   A positive IgE result = sensitisation, not necessarily true allergy.

•   Negative results reduce the likelihood of IgE‑mediated allergy, but don’t exclude non‑IgE causes.

•   Results must be interpreted in context—consider medical history and symptoms.

•   Further tests (e.g., challenge tests, skin prick, immunotherapy) might be needed

Summary

The ALEX² Allergy Explorer offers a single, comprehensive blood test to uncover allergies linked to hay fever, asthma, hives and food reactions. It features fast results, minimal disruption and molecular clarity—supporting personalised treatment plans and helping you avoid triggers so you can reduce exposure and minimise allergic reactions.
