Background: The World Allergy Organization estimate of allergy prevalence of the world’s population ranges between 30-40%. The prevalence of allergic diseases in the developing as well as developed world has increased over the recent decade. Skin prick test is useful in identifying the offending allergen and provides an opportunity for the overall management by allergen avoidance wherever possible and allergen specific immunotherapy. Methodology: Present study was conducted at allergy center, Kempegowda Institute of Medical Sciences (KIMS) Hospital & Research center, Bangalore over a period of 12 months. Skin Prick Test was done in 184 patients suffering from Nasobronchial allergy, by using 49 allergens extracts after taking informed consent from the patients. Allergen extracts included 19 pollens, 10 fungi, 5 dusts, 2 dust mites (Dermatophagoides farinae and Dermatophagoides pteronyssinus), 10 insects and 3 epithelia. Results: Out of 184 patients who underwent skin prick test,84(46%) were males and100(54%) were females. Majority i.e., 55% were in the age group of 21 -40 years. 68(37%) had family history of atopy.Out of 184patients 124(67%) were sensitive for one or more allergens. The common offending allergens found in the study were dust mites (DF and DP) -40.49% , dusts -15.22% , pollens –6.41%, insects -4.78% , fungi -2.17%, and epithelia –1.63% Conclusion: The most common allergens in Nasobronchial allergy were dust mites followed by dusts and pollens.
