50 patients of Bronchial Asthma were skin tested with fifty allergens of local importance. 90% cases gave positive results, pollen being the most common offender followed by fungi and dusts. Amongst the dusts House Dust accounted for more than halt of positive tests. In insects sex specific antigens were noted with respect to cockroaches. Skin tests were invariably positive in younger ages and in those with onset of Asthma dating back to childhood. Prausnitz Kustner test and Bronchial Sensitivity Test showed good corroboration with positive skin tests when considered patient wise. Pollen and dust in younger ages and pollen and fungi in older ages were the more common offender. Where attacks were irregular or perennial more than one allergen was responsible for the attacks Intrinsic asthmatics had more a seasonal pattern of attacks and no perennial pattern was noted.
