Marker of wound infection
First Claim
1. A system for use in the diagnosis and treatment of wounds comprising a diagnostic device, the diagnostic device comprising an indicator device adapted to give a detectable signal when the antioxidant capacity of a sample of a mammalian wound fluid exceeds a predetermined minimum level which is characteristic of an infection, the indicator device comprising a housing containing one or more reagents, the housing having at least one inlet provided therein for introduction of the sample, wherein the indicator device comprises a source of at least one reactive oxygen species and an indicator molecule that reacts with the reactive oxygen species to produce a detectable change, and a wound dressing comprising at least one antimicrobial agent, the wound dressing to be applied to the wound when the measured total antioxidant capacity is indicative of an infected wound.

Abstract
An indicator device adapted give a detectable signal when the antioxidant capacity of a sample of a mammalian wound fluid exceeds a predetermined minimum level which is characteristic of an infected wound. Also provided system for use in the diagnosis and treatment of wounds comprising the inventive diagnostic device and a wound dressing comprising at least one antimicrobial agent for selective application to infected wounds. Also provided are methods of diagnosis and treatment by means of the inventive device and system.
