Abstract
Devices and methods for sampling a biological fluid and measuring a target constituent within the biological fluid are provided. Generally, the subject devices include a sampling device configured to pierce a skin surface to provide access to biological fluid and concentrically-spaced working and reference electrodes positioned within the elongated sampling device that define an electrochemical cell for measuring the concentration of analyte within the biological fluid. The subject devices and methods are particularly suited for use in the sampling and concentration measuring of glucose in interstitial fluids. Also provided are kits that include the subject devices for use in practicing the subject methods.
