1. A method for determining an analyte in a sample comprising the steps of:

  • introducing a sample to be evaluated into an electrochemical test strip having working and counter electrodes;

    applying a potential between the electrodes sufficient to generate a diffusion-limited current when analyte is present in the sample;

    dynamically determining a time, tpeak, as the time when diffusion limiting current at the counter electrode is established;

    sampling the current value at a time, tmeas, wherein tmeas is after tpeak, and tmeas is determined based on the value of tpeak, and generating an indication of analyte in the sample based on the sampled current value at time tmeas.
