No seasonal influence of UV sunlight on patch test reactions in humans over a period of 9 year, of clinical practice was found in this retrospective study of almost 8OOO patients. Although the mean U V monthly dose varies seasonally, up in the summer and down in the winter, no significant differences could be identified for patch test reactions, either for the mean number of positive test reactions or for the intensity of the skin reaction or for the id‐like spread reactions seen in summer or winter. Furthermore, no short‐term influences of UV exposure during the weekend preceding patch testing could be demonstrated. Therefore, reliable patch‐test results can be expected at any season of the year from a general population, at least in Belgian‐type climates.
