1. A biological fluid constituent sampling and analyte concentration measurement device comprising:

  • (a) an elongated member having an open distal end configured to pierce a skin surface and to provide access to the biological fluid;

    (b) concentrically-spaced electrodes positioned within the elongated member that define an electrochemical cell for measuring the concentration of a target analyte within the biological fluid; and

    (c) a constituent transfer medium comprising a hydrophilic material in fluid communication with the elongated member and with the electrochemical, wherein the constituent transfer medium transfers at least one biological fluid constituent present at the open distal end of the elongated member into the electrochemical cell.
