Methods 7 085 patients were examined for tlgE and slgE to 15 allergens, based on the protocols of reversed enzyme allergosorbent test and the sandwich enzyme-linked immunosorbent assay. Results 3 758 (53.04%) patients tested positive for tlgE, and 4 640 (65.49%) for slgE. Der pteronyssinus, Derfarinae, eggs, and cow's milk were the most common allergens leading to higher positive rates of slgE responses. Several peaks of sensitization were: Der pteronyssinus, Derfarinae, and Blomia tropicalis at age 10-12; cow's milk at age below 3; eggs at age 4-6. The mean level and positive rate of tlgE tended to increase in subjects sensitized to more allergens. Sensitization to Der pteronyssinus (OR, 1.6; P〈O.05), Der farinae (OR, 1.5; P〈O.05), Blomia tropicalis (OR, 1.4; P〈O.05), Blattella germanica (OR, 1.5; P〈O.05), cow's milk (OR, 1.3; P〈O.05), and soy beans (OR, 2.0; P〈O.05) were independently correlated with allergy-related conditions in preliminary diagnosis. Conclusion The major allergens in Guangzhou include Derpteronyssinus, Derfarinae, cow's milk, and eggs. Sensitization to these allergens appears to be predictors of allergy-related disorder.展开更多
