Abstract: Objective    To evaluate the common allergens in Tianmen patients with allergic rhinitis and the distribution of allergic rhinitis in people of Tianmen. Method    All suspected allergic rhinitis cases underwent  skin prick tests with 11 kinds of aeroallergens. Results    Among all the patients, the positive skin reaction rate was 87%. The positive rate of Dermatophagoides pteronyssinus(Der p)was the highest， then followed up by Dermatophagoides farinae(Der f), Blomia tropicalis，Blatella germanica, dog hair. Most of patients who were positive reactivity in mites were concomitant reactivity to multiple allergens. There was no difference in the positive rates of skin reaction between males and females, but there was statistical significance between the adult and the children(P<0.05). Conclusion    Mite is the most prevalent allergen in Tianmen. The male and female had no difference in positive rates of skin reaction, and children have higher allergic positive rates than the adult.
