According to the individual action spectrum, characteristic wheals are often triggered after the light stairs have been carried out with UVA and UVB. In order to determine the exact action spectrum and the minimum dose of wheals, additional irradiation between 250 and 700 nm with a monochromator is recommended (but it is not necessary in clinical routine!). The test reactions are read immediately and within one hour after irradiation.
