title: [Urticaria, angioedema and complement abnormalities].
abstract: For urticaria and/or angio-oedema in a child, it may be valuable to measure some complement components, especially C3 and C4. If a state of hypocomplementemia is found, an attempt must be made to understand its significance. Is it consumption exaggerated by immune complexes in some urticarias of infectious or drug origin or urticarial vascularitis, or more exceptionally a congenital deficiency of some factors?
