A device and method for the rapid on-site detection of inhibitors of enzymes, such as, acetylcholinesterase is described where the device contains 2 reaction zones containing a reporter enzyme substrate. One reaction zone is for the test sample while the other is for an onboard negative control. Sample and control fluids are preincubated with the enzyme in separate reaction containers, then an aliquot of each reaction mixture is added to designated reaction zones on the test device. A purpose-built reader or an illuminating device, such as, containing an incandescent light source, a diode, a UV light source or any other illumination source that is suitable for the reporter or mere visualization is used to determine the level of reporter.

Rapid tests for the detection of inhibitors of enzymes and human exposure to the same

A device and method for the rapid on-site detection of inhibitors of enzymes, such as acetylcholinesterase, is described wherein the device contains all reagents added to a sample pad containing dried releasable enzyme creating a reaction mixture wherein inhibitor deactivates the enzyme, while said reaction mixture travels via a longitudinal membrane to a distal porous pad containing a substrate for the enzyme. The reaction of the enzyme and the substrate results in a product that can generate a measurable signal such as color, fluorescence or luminescence to serve as a reporter. Signal that is generated at this reaction zone is inversely proportional to inhibitor concentration in the test sample. A device containing two such strips, one for a test sample, the other for a negative control fluid as an onboard comparator is described. A purpose-built reader or an illuminating device, such as, containing an incandescent light source, a diode, a UV light source or any other illumination source that is suitable for the reporter or mere visualization is used to determine the level of reporter.
