Prevalence of gold contact hypersensitivity in the West of Scotland

373 patients attending for routine patch testing were tested with 0.5% and 0.05% gold sodium thiosulfate (GST). 8 (2.1%) patients had a positive patch test, and a further 4 (1.0%) patient reactions which were interpreted as irritant 2 out of 8 patients with a positive patch test to GST suspected gold allergy prior to testing, and both of these patients reported that their eczema resolved if they avoided gold jewellery. This is the lowest prevalence of hypersensitivity to GST reported and suggests that gold contact allergy may not be as widespread as has been recently proposed.
