Abstract [en]

Conventional skin UV-sensitivity phototesting is based on semi-quantitative assessment of minimal erythema dose (MED). This study demonstrates a method for quantitative MED determination, using a lengthwise attenuating UVB-field combined with tissue viability imaging (TiVi). The study aim was to investigate the agreement between MED acquired by traditional phototest and by the new method. Forty-seven voluntary subjects underwent phototesting with a traditional phototest and with the new technique. Test reading, carried out after 24 h, showed moderate agreement between the methods when assessed with TiVi (Kappa value=0.46) and visually (Kappa value=0.48). For the new method, no systematic differences were seen between outcomes assessed with TiVi or visually (95% CI for the mean difference=-1.6-2.0). In conclusion, the results give promising support for the concept of achieving a more precise MED estimation by combining continuous attenuating UV fields with new available bioengineering technology.
