ABSTRACT
Although the authors did not provide information on the rapidity of the initial patch test to diagnose allergy, they did suggest that active sensitization can occur, leading to a more rapid response on retesting. To diagnose contact allergy to gold sodium thiosulfate, readings at 3 days might be supplemented by readings at 1 and 3 weeks.4 All the patients remained positive for contact allergy to gold sodium thiosulfate from the point of their initial diagnosis to the time of this study.
