Urticaria Control Test (UCT)

Retrospective (4-week) disease control in chronic urticaria, four items each 0-4 (range 0-16); ≥12 = well-controlled.

Evidence tier: Validated instrument.

Formula / logic

UCT = sum of four items, each scored 0-4 (higher = better control); range 0-16. Cutoff ≥12 = well-controlled; 16 = complete control.

Interpretation

Validated control instrument for CSU and chronic inducible urticaria; the ≥12 threshold and MID of ~3 points come from the validation study.
