1. An analyte detection system for detecting more than one analyte, the system comprising:
- an analyte detection device configured to measure a concentration of first and second analytes in a material sample;
a processing circuit configured to determine whether a concentration of said first analyte falls within a previously-specified range, and activates said analyte detection device to measure a concentration of a second analyte if said concentration of said first analyte falls outside of said previously specified range.

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.

16. A device for measuring a concentration of an analyte in a material sample, said device comprising:
-
an optical source configured to emit electromagnetic radiation in a range of about 4.275 to about 10.060 μ
m;
a detector positioned with respect to the source, so that the source and the detector define an optical path therebetween;
a sample element configured to support a material sample in said optical path;
a first array of filters disposed in said optical path between said sample element and said source, said first array of filters being configured to allow electromagnetic radiation of a first set of previously determined values to impinge on the sample element, the first set of previously determined values associated with a first analyte;
a second array of filters disposed in said optical path between said sample element and said source, said second array of filters being configured to allow electromagnetic radiation of a second set of previously determined values to impinge on the sample element, the second set of previously-determined values associated with a second analyte . - View Dependent Claims (17, 18, 19, 20)
