1. An analyte detection system for detecting more than one analyte, the system comprising:
- an analyte detector in fluid communication with a source of a material sample and configured to measure a first characteristic of the material sample;
a processing circuit in electronic communication with the analyte detector, the processing circuit configured to use the first measured characteristic to determine the concentration of a first analyte in the material sample and compare the concentration of said first analyte to a range given by an upper and a lower value of concentration, the processing circuit further configured to activate said analyte detection device to measure a second characteristic of said material sample, if the concentration of the first analyte is outside the range, and use the second measured characteristic to determine the concentration of a second analyte.

Abstract
An analyte detection system is configured to measure concentrations of at least first and second analytes in a single material sample supported by a sample element. The measurement of a second analyte can be conditioned on a quantitative or qualitative result of the first measurement. In one embodiment, the first analyte is glucose and the second analyte is a ketone. According to such an embodiment the ketone is measured if the result of the glucose measurement exceeds a previously-specified value or falls outside of a previously-specified range.
