1. A method for determining a concentration of blood glucose comprising:

  • providing a blood glucose solution on a test strip comprising an enzyme;

    detecting a change in accumulation of a product of a chemical reaction occurring in response to said blood glucose solution on said test strip;

    representing said change in accumulation of a product as an analog signal;

    converting said analog signal to a digital signal;

    converting said digital signal to a wave pattern having a first time and a second time, wherein the first time comprises an initial time and wherein the second time corresponds to a peak value;

    calculating a difference value between said first time and said second time, wherein said difference value comprises a rising time of said wave pattern; and

    correlating a concentration of said blood glucose to said rising time.
