Topic Area


The diagnosis of acute urticaria is basically clinical and infections (in particular viral infections) account the far most common cause during childhood. Testing patients for allergies is indicated only when there is a close temporal relationship between food ingestion and the appearance of urticarial eruption: laboratory investigations are not indicated in first instance, it is appropriate to limit allergologic tests to the skin test (SPT) by using commercial extracts or fresh food (prick by prick).
