Abstract
In patch testing, a standardized manner of testing and of patch test reading is essential. In this chapter, the basic aspects of these issues are discussed, as well as thoughts on when patch testing should be probably, with what to patch test, especially considering the baseline series, and pitfalls when patch test reading.
