What is the best evaluation for angioedema and urticaria? Evidence-Based Answer: Evidence is insufficient to recommend any particular stepwise workup for angioedema and urticaria, as even with significant testing the etiology is idiopathic in up to 82% of cases. Consensus opinion recommends being guided by a thorough history and physical examination (SOR: C, nonconsecutive observational studies and consensus opinion).
