Urticaria Activity Score
Urticaria activity score (UAS7) is a scoring system, which is helpful for evaluation of spontaneous urticaria severity. It is a questionnaire-based system which mainly inquire about pruritus and wheals experienced by the patients.
| Score | Wheals | Pruritus |
|---|---|---|
| 0 | No wheals have been appeared | Patient didn't experience any pruritus |
| 1 | Appearance of less than 20 wheals within 24 hours | Patient experienced pruritus, nevertheless it didn't annoy the patient |
| 2 | Appearance of 20 to 50 wheals within 24 hours | Patient felt annoyed with pruritus, nevertheless it didn't interfere with him/her daily activities or sleep |
| 3 | Appearance of more than 50 wheals within 24 hours or involvement of a large surface of body with confluent wheals | Patient felt annoyed with pruritus and it interferes with him/her daily activities or sleep |
Ice Cube Test
Ice cube test is recommended as a diagnostic test in order to diagnose cold-induced urticaria. This test is performed by applying a plastic bag containing melting ice cubes on the patient's forearm for 5 minutes. Appearance of wheal within 10 minutes after removing the plastic bag is considered a positive test.[1]
