Overview
Urticaria activity score (UAS7) is a questionnaire-based scoring system which inquires about pruritus and wheals experienced by the patients. It is helpful to determine the spontaneous urticaria severity. Moreover, there is another diagnostic test, named ice cube test in order to diagnose cold-induced urticaria. The aforementioned test is a practical method to observe wheals appearance after cold exposure.
Other Diagnostic Studies
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 scoring system which mainly inquires about pruritus and wheals experienced by the patients. [1][2]
| 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 |
- Scores have a range of 0 to 6 for each 24 hours.
- Scores should be measured for the whole week, which can have a total range of 0 to 42.
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.[3]
