Methods and apparatuses for electrically connecting a medical glucose monitor to a glucose sensor set, as well as for testing the operation of the glucose monitor, monitor cable and glucose sensor set are provided. In one embodiment, an electric cable comprises a cable member, a first connector and a second connector. The cable member in turn comprises at least one insulated conductor, a conductive shielding layer disposed around the at least one insulated conductor; and an insulating layer disposed around the conductive shielding layer. A glucose monitoring system test plug provides for a releasable electrical connection with the electric cable. In one embodiment, the test plug comprises a housing and a fitting affixed thereto which is adapted to electrically couple the test plug with the electric cable. The test plug further includes an electrical circuit that produces a signal that is read by the glucose monitor to test the operational performance of the glucose monitor and the electric cable when the test plug is coupled to the electric cable and when the electric cable is coupled to the glucose monitor.

The present invention is related to optical non-invasive methods and instruments to detect the level of analyte concentrations in the tissue of a subject. The spectra of mid-infrared radiation emitted from a subject's body are altered corresponding to the concentration of various compounds within the radiating tissue. In one aspect of the invention, an instrument measures the level of mid-infrared radiation from the subject's body surface, such as the eye, and determines a specific analyte's concentration based on said analyte's distinctive mid-infrared radiation signature.
The present invention is related to non-invasive methods and instruments to detect the level of analyte concentrations in the tissue of a subject by measuring electromagnetic radiation signatures from the subject's conjunctiva. The spectra of mid-infrared radiation emitted from a subject's body are altered corresponding to the concentration of various compounds within the radiating tissue. In one aspect of the invention, an instrument floods the conjunctiva of the subject with electromagnetic radiation in the mid-infrared range and measures analyte concentrations based on mid-infrared radiation reflected back to the instrument.
