The objective of this paper is to present trends in contact sensitization from the DKG and IVDK patch test clinics, which have led to changes in the DKG standard series (as of 1.1.2014), as well as the current legal framework which has influenced these trends and the way patch testing is performed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Patients and methods<\/jats:title><jats:p>The patients from 56 DKG and IVDK patch test clinics from 2010 (n = 13,117), 2011 (n = 13,320) and 2012 (n = 12,529) were analyzed with regard to frequencies of sensitization (hit list) to contact allergens as well as the location of allergic contact dermatitis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>With a sensitization rate of 15 % nickel is still the most frequently recognized contact allergen. An increase can be observed for fragrance mix I (9.1 %), the preservative composition of methylchloroisothiazolinone\/methylisothiazolinone (MCI\/MI) (4.5 %) and methylisothiazolinone (MI) alone (6.8 %). A decline is present for potassium dichromate from above 6 % (2007) to 3 % (2012) and for bufexamac (currently at 0.6 %).
