F, food allergen sensitized patients; A, aero-allergen sensitized patients.
Pattern of SPT positive aero-allergens among male and female patients. Total counts: house dust, 78.06%; pollens, 73.05%; thrashing dust, 67.64%; raw cotton, 56.90%; poly sensitization, 82.93%.
Association of professions with aero-allergic disease pattern. AR, allergic rhinitis; BA, bronchial asthma; A&B, allergic rhinitis and bronchial asthma; Urt, urticaria; AE, allergic eczema; AC, allergic conjunctivitis.
