What to Expect: Fluorescent UVA1 Minimal Erythema Test
This is the tenth video in our 'What to Expect' series. The video shows the process of light sensitivity testing using a fluorescent ultraviolet-A1 (UVA1) light source. This test determines a starting dose for UVA1 phototherapy or is used to investigate light sensitivity (photosensitivity) at the Scottish Photobiology Unit in Ninewells Hospital, Dundee, Scotland.
