nSus s – a pig allergen component, serum albumin, which is excreted in the animal's urine and spread by microscopic dust particles in the air. Sus s1 is a respiratory and food allergen component found in pig dander, meat, milk, and saliva. This protein is thermolabile and denatures during food processing. Sus s1 belongs to serum albumins and shows cross-reactivity with other mammals.
Sus s1 is an important marker of sensitization to pig allergens. Contact with this allergen component most often occurs during food consumption and preparation, as well as in occupational settings. It is known that Sus s1 cross-reacts with serum albumins of other animals, including cats (Fel d2), chickens (Gal d5), and cows (Bos d6), which can influence the clinical picture of allergy. This test helps identify potential cross-allergic reactions, which is important for comprehensive treatment and prevention.
FEIA (Fluorescence Enzyme Immunoassay) using ImmunoCAP (Solid-phase Immunofluorescence) – quantitative determination of sensitization level.
