What's included

6 deliverables in this treatment

  • IgE testing against 117 allergen extracts (pollen, dust mites, pets, moulds, foods)
  • IgE testing against 178 molecular allergen components (component-resolved diagnosis)
  • Cross-reactive carbohydrate determinant (CCD) identification
  • Single blood draw — no separate skin prick appointments needed
  • Phlebotomy included
  • Results report within 1–2 weeks

The ALEX2 Comprehensive Allergy Panel tests IgE reactivity against 295 allergens — 117 standardised extract-level allergens plus 178 molecular (component-resolved) allergens — in a single blood sample. This is the most extensive allergy testing methodology available outside of specialist immunology centres, covering pollen (grasses, trees, weeds), house dust mites, pet dander, moulds, and a wide range of food allergens. By testing both extract-level and molecular allergen components simultaneously, ALEX2 distinguishes true primary sensitisation from cross-reactive false positives — a critical advantage over skin-prick testing or single-allergen IgE panels. Results within 1–2 weeks require physician interpretation to translate the 295 results into a meaningful clinical picture.

About this treatment

Allergic disease affects approximately 40% of the European population and is increasing in prevalence due to environmental changes, dietary shifts, and the hygiene hypothesis. Accurate identification of the causative allergens — rather than empirical avoidance of broad food categories or environments — enables targeted allergen avoidance, specific immunotherapy planning, and informed decision-making about dietary restrictions. The ALEX2 allergy…

Who is this for?

Adults and children with suspected allergies to multiple sources — pollen, food, pets, or dust mites — who want a definitive one-visit test rather than repeated skin-prick appointments, or who need to plan specific allergen immunotherapy.

Preparation required

Fasting not required. Inform staff of any antihistamine use — high-dose antihistamines may mildly suppress IgE levels but blood testing is far less affected than skin-prick testing. Physician consultation recommended before ordering to define clinical priorities.

Panel categories

Allergy Panel

Biomarkers tested

5
Histamine
IgE kU/L

Immunoglobulin E (IgE) is a protein associated with allergic reactions that is normally found in very small amounts in the blood. IgE functions as part of the body's immune system (its defence against 'intruders').

IgG mg/dL

Immunoglobulin G (IgG) is the most common type of antibody in the blood, important for fighting bacterial and viral infections.

pH pH units

Imbalances in gut pH influence short-chain fatty acid production and their effects.

Clinical team

IFCOR was founded and is led by RNDr. František Flek, who established the original allergy and immunology laboratory in 1994. The network holds ISO 15189:2013 accreditation across five facilities (ČIA number M 8106) and participates in four external quality assurance programmes: SEKK, EHK SZÚ Prague, Instand, and ÚHKT. The Jihlava laboratory team covers nine specialist disciplines — clinical biochemistry,…
