The Prurigo Control Test (PCT) is a validated, user-friendly designed instrument to assess disease control in patients with chronic prurigo.

The PCT is a retrospective instrument and can be evaluated directly, quickly and easily. Its cut-off value of 11 points helps to distinguish patients with poorly controlled chronic prurigo from patients with well-controlled disease.

The PCT was developed at the Charité and Münster University Hospital by a team led by Dr. Karsten Weller and Prof. Martin Metz.
