Hypersensitivity to iodinated contrast products (ICP) affects 1 to 3% of injected patients. These reactions require an allergological assessment with skin tests in order to distinguish allergic immunological mechanisms from other non-specific mechanisms. Current recommendations recommend carrying out prick tests followed by intradermal reactions up to a 10th dilution. However, undiluted IDRs are carried out by several teams under certain conditions, without this having been validated. Experience tends to show that these IDRs are relevant in certain patients to make the diagnosis without risk.
