Incremental doses of various schedules used for DBPCFCs. Individual doses are expressed as micrograms of protein in the food administered during the active food challenge. Schedules shown are either generic or derived from those devised for challenges with cow’s milk. The numbers shown with symbols refer to the source publications in the reference list.

Scoring the challenge outcome (modified from Bock et al65 and Nowak-Wegrzyn et al14). The scoring system proposed here can be used for IgE-mediated reactions to determine the degree of response in various target organs and changes from baseline. Challenges should usually not commence if there are baseline symptoms exceeding descriptions in green (an exception might be AD that remains moderate despite maximal therapy). See the text for additional comments. (Please note that I,C,1 was made orange because it is similar to mild objective symptoms in other areas, is not a stopping indication, and, depending on clinical judgment, might or might not represent contact urticaria).
