Patent ID: 8231832

Claim:
An arrangement constructed and arranged to detect the presence or concentration of an analyte present in bodily fluid, the arrangement comprising: a channel member configured to receive a sample of the bodily fluid from a conduit; an assay pad in fluid communication with the channel member, the assay pad containing a reagent; a plurality of detectors, each detector constructed and arranged to produce a signal indicative of a reaction between the analyte and the reagent; and electronics constructed and arranged to monitor and interpret the signals produced by the plurality of detectors to provide the following outputs: (i) an estimate of the volume of the sample received by the channel member based at least in part on the number of detectors that produce a signal indicating a reaction between the analyte and the reagent; and (ii) information about the kinetics of the reaction between the analyte and the reagent based at least in part on the time between signals.
