Contact sensitization to 34 common contact allergens in university students in Beijing

Epidemiological studies of contact allergy in the general population provide important evidence for the prevention of contact allergy. In 2010, we reported frequencies of contact allergy to 20 common allergens selected from the European baseline series in university students in Beijing (1). In the present study, we tested 34 common allergens selected from the European baseline series and a cosmetic series to investigate possible changes concerning common contact allergens in the general population in Beijing.
