			==Evaluation==
			*Cold Stimulation Test (CST) is main diagnostic test<ref name=Hochstadter />
			**Ice cube (or other object at 0-4° C) placed on forearm for 5 minutes
			**Test is positive if weal develops after 5-10 minutes of rewarming
			*Consider lab testing:
			**CBC if suspect infection
			**C1 esterase inhibitor level in cases of angioedema
			**ESR/CRP if suspect underlying autoimmune disease

	==Management==		==Management==
	*~~Treat similarly to urticarial lesions from other causes~~ (~~i.e. antihistamines~~)		*[[Antihistamines]] (preferably second generation)
