The Angioedema Activity Score (AAS) allows the patient to score each of five key factors relating to their experience of angioedema from 0 to 3 (giving a daily score of 0–15) Daily AAS can be summed to provide 7-day (AAS7), 4-week (AAS28), and 12-week (AAS84) scores Assessment of quality of life in chronic urticaria
