1. A method of determining analyte concentration in a physiological fluid, comprising:
- receiving, by a test meter, a sample of physiological fluid ;
causing a current to run through the fluid sample;
sampling the magnitude of the current a plurality of times to form a plurality of analog to digital (A/D) conversions;
discarding a subset of the plurality of A/D conversion, based on the magnitudes;
generating an analyte concentration based on the remaining A/D conversions;
identifying the presence of the fluid in a position to be detectable by the meter; and
determining whether the identification is in error.

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.
