PURPOSE: To investigate the main characteristics of HDM-induced allergic diseases in children and to explore allergen component-specific sensitization patterns, features, and correlations with clinical symptoms. METHODS: Serum samples were collected from children with HDM-induced allergic diseases. Information on age, sex, and clinical symptoms was recorded. A protein chip method was used to detect specific IgE (sIgE) against HDM components, including RESULTS: 116/120 (96.67%) exhibited positive reactions to HDM components. The highest positive rates were for
