1. A glucose measurement system comprising:
a biosensor having a plurality of electrodes with a reagent disposed thereon; anda meter including:
a microcontroller coupled to a power source, memory and the plurality of electrodes of the biosensor and in which the microcontroller is configured to:
apply a signal to the at least two electrodes after application of a fluid sample proximate the at least two electrodes to start a test measurement sequence for an electrochemical reaction of the glucose in the fluid sample with the enzyme;obtain an estimate representative of the glucose in the fluid sample from respective output signals of each of the plurality of the electrodes at a plurality of selected time intervals from the start of the test measurement sequence;obtain another estimate representative of the glucose in the fluid sample from a combination of respective output signals from the plurality of electrodes at a plurality of specific time intervals from the start of the test measurement sequence; anddetermine a final glucose value of the fluid sample from a median of all the estimates of the glucose in the fluid sample.
