Cold temperature challenges for acquired cold urticaria

In summary, I concur that the Peltier method can provide a standardized cold test for patients with acquired cold urticaria and for patients with convincing histories of cold urticaria who have a negative test result at 0°C to 4°C. However, I believe there is also value in performing the cold stimulation time test, either with the Peltier device or with ice in a plastic bag, to test for therapeutic efficacy and to predict spontaneous remission.
