We have prospectively performed patch and intradermal tests on 105 consecutive patients, attending for patch testing, to determine the optimum method of screening for corticosteroid hypersensitivity. Patch tests with Pivalone and a corticosteroid series (all 1% in ethanol) detected all the patients with steroid sensitivity. However, intradermal tests were essential to exclude false positive reactions and detect all relevant steroid allergies in any individual patient.
