Objective To test the allergen‐specific‐IgE in different districts for bronchial asthma children ,and analyze the re‐sults .Methods The blood samples of bronchial asthma children which selected from Heyuan City and Shenzhen City were detected by using German Ormond Western Blot Method reagents .Results The total positive rate of bronchial asthma children′s allergen‐specific‐IgE from Heyuan was 61 .7% .The positive rate of inhalation allergen was 43 .4% .The top three of inhalation allergens were house dust(41 .7% ) ,combination of mole(33 .3% ) ,the dog epithelium(20 .0% ) .The positive rate of food‐borne allergen was 36 .7% .The top three of food‐borne allergens were milk(33 .3% ) ,peanut(23 .3% ) ,beef(11 .7% ) .The total positive rate of bron‐chial asthma children′s allergen‐specific‐IgE from Shenzhen was 86 .7% .The positive rate of inhalation allergen was 73 .3% .The top three of inhalation allergens were combination of mole (63 .3% ) ,house dust (61 .7% ) ,The Liu/Yang/Elm combination (33 .3% ) .The positive rate of food‐borne allergen was 58 .3% .The top three of food‐borne allergens were shrimp(31 .7% ) ,crab (28 .3% ) ,the cod/lobster/scallop combination(21 .7% ) .Conclusion There were different parterns of the positive rate of bronchial asthma children′s allergen‐specific‐IgE in different districts .
