Introduction: Clinical history and examination are very important for determining allergy. The most common forms being bronchial asthma (BA) and allergic rhinitis (AR). A lot of patients respond to the primary line of treatment. Patients come forward with the objective of uprooting the cause of these allergies. Skin prick test (SPT) helps in finding the most likely cause after which we can offer them the desensitization and protective advice. Objective: To evaluate the performance of various aeroallergens by assessment with SPT in Central India population. Materials and Methods: One hundred and forty-three patients with BA and AR were subjected to SPT. SPT was performed with antigen extracts from India. Results: Of the 143 patients, 86 (60%) patients had both BA and AR. These 143 patients showed 454 positive SPT results. Of the 454, 223 (49%) were positive for mites alone. Among the three mites tested for, Dermatophagoides pteronyssinus 81 (17.8%) was the most common. The study of seasonal distribution of allergens showed peaked results for mites in winter. Parthenium hysterophorus (congress grass) 11 (7.7%) was the most common pollen found. Conclusions: The dust mite had the greatest frequency in this study. Humidity levels are critical for the growth of mites, which provides a valuable clue to protect against it. Avoiding the relevant allergens can be a remedy for AR patients and reduce the frequency of symptoms in asthmatics.
