[Photopatch testing].
This article reminds a review of photopatch tests with detailed analysis of: (1) materials used for double patch tests, and where possible, triple copies, one of which is protected from light while the other is exposed to UVA (5mJ/cm2) and the other exposed to UVB or a total spectrum of 0.75 DEM (minimum erythematous dose), with at least two readings; (2) interpretation of results to distinguish between contact allergy, contact photoallergy and/or phototoxicity; (3) materials used for UV exposure; (4) the list of (photo)allergens used in a standard series and/or a series specifically suited to the patient as well as suppliers of such series; (5) finally, the circumstances prompting photodermatological exploration.
