- Abstract
All skin tests were negative, except in one patient who showed an immediate positive SPT to Gb, which was the involved GBCA. Adverse reactions to GBCA were immediate in 13 patients (12 urticaria and 1 anaphylaxis), and delayed exanthema in the remaining 3. Negative predictive value of skin tests to GBCA has been estimated in 84%.1 Thus, more than 10% of patients could react using an alternative negative skin-tested GBCA, and good tolerance to GBCA should be confirmed through a single-blind placebo-controlled drug challenge test (DCT).4.
