title: Phototesting and photopatch testing: when to do it and when not to do it.
abstract: Phototesting and photopatch testing are among the most important tests in the evaluation of photodermatoses, yet their use has been restricted to specialized centers. To assist clinicians interested in conducting these procedures and in updating their techniques, we asked 4 experts to comment on these tests in the context of diagnostic approach to the photosensitive patient. A list of photoallergens and a protocol for their use is provided.
