Abstract

A system and method of processing a test current for an analyte measurement in a fluid using a test strip and a test meter are disclosed. The method comprises sampling the test current at a pre-determined sampling rate to acquire a plurality of A/D conversions. The method also comprises filtering out at least a highest magnitude A/D conversion and a lowest magnitude A/D conversion leaving a plurality of accepted A/D conversions. Further, the method comprises calculating an average or a summation of the plurality of accepted A/D conversions and converting the average or the summation into a glucose concentration.
