ALEX Molecular Allergy Test

ALEX is a comprehensive molecular allergy blood test screening 218 molecular allergens and 82 extracts at once — pollens, foods, animals, moulds and more — from a single sample. Self-pay, no referral, results electronic.

The ALEX (Allergy Explorer) test is a comprehensive molecular allergy panel that screens 218 individual molecular allergen components and 82 allergen extracts from a single blood sample — covering pollens, foods, animal dander, house-dust mites, moulds, insect venoms and more. By measuring at the molecular-component level rather than just whole extracts, it can distinguish genuine sensitisation from cross-reactivity, helping build a far more precise allergy profile than traditional broad tests. SYNLAB Czech offers ALEX on a self-pay basis through its e-shop: order online, attend any SYNLAB collection point for a single venous draw, and receive your results electronically from SYNLAB's accredited laboratories — no referral or insurance required. A separate food-intolerance test is also available for those focused specifically on dietary triggers. The breadth of ALEX makes it well suited to people with complex, multi-trigger or unexplained allergy symptoms who want a single comprehensive screen. Results are best interpreted with an allergist, who can relate the molecular findings to your clinical history and guide avoidance or immunotherapy decisions.
