Abstract

An apparatus for extracorporeal treatment of blood () has a supply line (), a waste line () and an ultrafilter () inserted in the supply line (). An air inlet line is connected to the first chamber () of the ultrafilter () and a pressure sensor () configured for detecting pressure in the waste line (). A controller () is configured to carry out, with the hydraulic circuit () in by-pass configuration, an integrity test procedure for detecting if the ultrafilter membrane has multiple or single fiber breaks. A method of testing the ultrafilter () is also disclosed.
