Abstract:
1. A method of determining concentrations of a plurality of analytes from a single blood sample, placed in a single opening, the method comprising: (a) placing said single blood sample in an opening; (b) absorbing said blood sample with a test matrix that includes a plurality of layers and a chromogenic agent; (c) generating a colored response with said test matrix wherein said colored response is proportional to a concentration of a first analyte; (d) drawing a portion of said single blood sample into a capillary tube; (e) contacting said portion of said single blood sample with an electrode and a counter-electrode; and (f) measuring an electrical property of said single blood sample though said electrode and counter-electrode wherein said electrical property is proportional to a concentration of a second analyte in said single blood sample.
