    摘要： A device for detecting a mammalian host-derived enzyme in a sample of a wound fluid, said device comprising: a housing having an inlet for the sample and side walls defining a fluid flow path extending from said inlet an indicator moiety that is bound to a solid substrate by means of a peptide linker moiety that is cleavable by said host-derived enzyme, said solid substrate being located in a reaction zone of said fluid flow path; and a detector moiety located in a detection zone downstream from the reaction zone in said fluid flow path, wherein the detector moiety interacts with an indicator moiety that has been cleaved from said solid substrate to produce a detectable change in said detection zone. Suitably, the device further comprises a control moiety located in a control zone in said device, wherein the control moiety can interact with a component of the wound fluid sample to improve the accuracy of the device. Also provided are systems comprising a device of the invention and a swab or biopsy punch adapted for use therewith.
