Alexander, 35 years from Czechia

• The morning after meat consumption the bite sites were reddened, inflamed and still itchy.
• The question arises: is it meat allergy?
• ALEX³ was performed - it covers the following meat allergens: Ach d (house cricket); Bos d_meat, Bos d 6 (cattle); Equ c_meat (horse); Gal d_meat, Gal d 7 (chicken); Loc m (migratory locus); Mel g (turkey); Ory c_meat (rabbit); Ovi a_meat (sheep); Sus d 1 (pork); Ten m (mealworm)
• No allergens were positive, except for one: Alpha-gal!
• Alexander shows clinically relevant sensitisation to red meat

• Before the tick bite, Alexander had never shown any signs of meat allergy or alpha-gal syndrome (ALEX² and FOX have been tested previously)
• He sensitised to alpha-gal by a tick bite and now shows clinically relevant allergy to meat
• ALEX³ detected positive IgE to alpha-gal (2.25 kUA/L)
• Strict avoidance of red meat is recommended
• ALEX³ includes alpha-gal as regular allergen spot

Novel findings revealed by ALEX³

• Alpha-gal syndrome
