Abstract:
1. A method of assaying an enzyme in a sample of blood or blood derivative by detecting an electroactive reaction product thereof, comprising the steps of: introducing the sample into a cartridge which includes an analysis location, metering a portion of the sample in a holding chamber terminating in a capillary stop, moving the metered sample through the capillary stop to the analysis location, mixing the metered sample with reagent at the analysis location, allowing the enzyme to react with the reagent to form the electroactive reaction product in the sample, positioning the sample at an amperometric sensor in the analysis location, and detecting the electroactive reaction product of the enzyme reaction using the amperometric sensor, wherein the electroactive reaction product may be correlated to the amount of enzyme in the sample of blood.
