What's included
6 deliverables in this treatment
- Venous blood draw performed by a trained phlebotomist
- Simultaneous testing of 280+ allergen components (molecular allergen components, not just extracts)
- Allergen categories: tree and grass pollens, house dust mites, moulds, animal epithelia, insect venoms, food proteins (milk, egg, wheat, soy, nuts, shellfish, legumes, fruits)
- Luminescence-based multiplex immunoassay (ALEX2 platform) — identifies sensitisation at molecular component level
- Printed laboratory report with component-level IgE values and reference ranges
- Optional laboratory consultation to review results (by arrangement)
The ALEX Allergy Xplorer panel is one of the most comprehensive single-draw allergy blood tests available in Europe, testing sensitisation to more than 280 allergen components from a single venous sample. Unlike skin-prick tests or standard single-allergen IgE panels, ALEX2 uses multiplex luminescence immunoassay technology to measure specific IgE antibodies at the molecular component level — identifying exactly which protein within a pollen, mite, or food is triggering a response. At Laboratoře Mikrochem, this analysis is performed in their ISO 15189-accredited immunology laboratory in Olomouc, with results available within 7 working days. The panel covers all major inhalant allergens (grass, tree, and weed pollens; dust mites; moulds; animal epithelia), insect venoms, and a broad food allergen set including milk proteins (casein, whey), egg, wheat gluten, soy, tree nuts, peanuts, shellfish, and tropical fruits. A single venous blood draw is all that is needed — no repeated skin punctures, no allergen exposure on the day.
About this treatment
The ALEX Allergy Xplorer (ALEX2) panel is a state-of-the-art multiplex allergy diagnostic that tests specific IgE antibody levels against more than 280 individual allergen molecules from a single tube of blood. It is among the most comprehensive allergy blood tests commercially available and is increasingly used by allergologists across Central Europe to replace or supplement conventional skin-prick testing — particularly for patients with complex or…
At Laboratoře Mikrochem's ISO 15189-accredited Olomouc laboratory, the ALEX2 assay uses luminescence-based multiplex immunoassay technology: allergen components are arrayed on a solid-phase matrix and incubated with the patient's serum; a fluorescent anti-IgE antibody then reveals which specific molecules triggered IgE production. The result is a quantified IgE titre for each component, expressed in kUA/L, allowing the allergologist to distinguish between…
The panel is divided into seven major categories. Inhalant allergens include over 50 grass, tree, and weed pollen components (including the major cross-reactive allergen groups PR-10, profilins, and polcalcins), house dust mite proteins (Der p 1, Der p 2, Der p 23), storage mites, moulds (Alternaria, Cladosporium, Aspergillus), and animal dander proteins from cat, dog, horse, and rodents. Insect venom components cover bee and wasp venom proteins including…

Who is this for?
Adults or children with unexplained allergic symptoms (rhinitis, asthma, eczema, urticaria, food reactions, suspected insect venom allergy) where conventional skin-prick tests have been inconclusive or incomplete. Also suited to anyone who has already had individual allergen tests and wants a comprehensive picture in one draw.
Preparation required
No fasting required. No antihistamines needed — this is a blood test, not a skin challenge. Arrive at any collection point from 07:00. No appointment necessary for a walk-in blood draw.
Panel categories
Biomarkers tested
5Immunoglobulin 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').
Immunoglobulin G (IgG) is the most common type of antibody in the blood, important for fighting bacterial and viral infections.
Imbalances in gut pH influence short-chain fatty acid production and their effects.
