1. A system for analyzing a disposable cartridge to measure a quantity of a breath analyte captured by an interactant contained in the disposable cartridge, the system comprising:
a cartridge holder that holds the disposable cartridge;
a first plurality of light emitting diodes (LEDs) that emit light of a first wavelength, the first plurality of LEDs arranged to illuminate the disposable cartridge when the disposable cartridge is positioned within the cartridge holder;
a second plurality of LEDs that emit light of a second wavelength, the second plurality of LEDs arranged to illuminate the disposable cartridge when the disposable cartridge is positioned within the cartridge holder;
a photodiode positioned to measure light reflected from the disposable cartridge when the disposable cartridge is illuminated; and
a processor configured to use the first and second pluralities of LEDs and the photodiode to generate at least (1) a first measurement of an intensity of light of the first wavelength reflected from the disposable cartridge, and (2) a second measurement of an intensity of light of the second wavelength reflected from the disposable cartridge, wherein the processor is configured to generate the first and second measurements at different respective times during a time period in which a reflectance of the interactant is changing as a result of a chemical reaction involving said breath analyte.
