Abstract

Positive reactions to patch tests must be carefully evaluated in order to judge their clinical relevance, in terms of any relation between the positive reaction and the patient’s dermatitis. Such relevance may be present (related to the current dermatitis), past (related to past clinical events, not correlated to the current complaint), and unknown (related to some clinically latent sensitization). The assessment of clinical relevance of a patch test reaction is a complex process with many possible pitfalls.

Keywords
