MONITORING OF WOUNDS BY MEASUREMENT OF PROTEASE AND PROTEASE INHIBITOR LEVELS IN WOUND FLUIDS

摘要

A diagnostic test apparatus for determining a ratio of: (a) at least one endogenous protease enzyme inhibitor, to (b) at least one endogenous protease enzyme, in a sample of a wound fluid. Suitably the protease enzyme is a neutrophil elastase and the protease enzyme inhibitor is alpha-1-antitrypsin. Also provided are wound treatment systems comprising an apparatus according to the invention and a wound dressing comprising an oxidized cellulose. Also provided are methods of diagnosis, prognosis and treatment of wounds using the apparatus and systems of the invention.
