　Background : We have reported the positive rates of Japanese standard allergens (JSA) since 1994. Objective : To examine JSA-positive rates. Subjects : 2,209 cases (male, n=533 ; female, n=1,676) in 2013 and 1,929 cases (male, n=424 ; female, n=1,505) in 2014. Results : The positive rates in 2013 and 2014 were high for the following allergens : nickel sulfate (15.1 and 16.7%, respectively) , urushiol (10.5 and 12.5%, respectively) , cobalt chloride (8.8 and 8.4%, respectively) , p-phenylenediamine (7.2 and 7.7%, respectively) , fradiomycin sulfate (7.7 and 7.6%, respectively) , gold sodium thiosulfate (5.2 and 5.7%, respectively) , and fragrance mix (6 and 5.6%, respectively) .
