1. A method for measuring analyte levels in a body fluid, comprising:

  • providing an analyte level detection device that includes an analyte detecting member;

    the analyte detecting member including a biosensor electrode that includes a cross-linkable hydrophilic polymer dispersion containing a hydrophilic monomer mixture, a low molecular weight cross-linker and a hydrophilic high molecular weight polymer and an initiator, the biosensor including a zwitterionic-surfactant, the hydrophilic molecular weight polymer including a non-ionic co-surfactant, the co-surfactant having surface active properties that increase a mobility of a mediator, the biosensor electrode having an upper portion distal from a substrate that is wider that a lower portion coupled to the upper portion and to the substrate, at least a portion of the biosensor electrode being screen printed.
