1. A method of determining a concentration of glucose in blood, the method comprising:

  • stimulating a region of skin other than a fingertip for a period of time adequate to obtain a glucose concentration measurement that is at least 10% closer to a glucose concentration determined from blood obtained from a fingertip measurement than a determination of a glucose concentration from blood obtained from the region of skin without stimulating;

    after stimulating the region of the skin, lancing the skin to cause a flow of blood from the region;

    contacting a portion of an electrchemical sensor to the blood and transporting at least a portion of the blood to a sample chamber of the electrochemical sensor; and

    electrochemically determining the concentration of glucose an the blood sample.
