Systems, devices and methods for determining the concentration of
physiological fluid analytes are provided. The subject systems have a
plurality of biosensor devices present on a disposable cartridge. Each
biosensor device includes a biosensor and a skin penetration means. In
practicing the subject methods, a movement means of the device is used to
move each biosensor device in a first direction that provides for
penetration of the skin-piercing means into a skin layer followed by
movement of the biosensor in a second direction that provides for removal
of the skin-piercing means from the skin layer, where this movement
profile provides for physiological fluid access and analyte concentration
determination by the analyte sensor means. The subject systems, devices
and methods for using the same find use in determining the concentration
of a variety of different physiological fluid analytes, and are
particularly suited for use in detection of physiological fluid glucose
concentration.
