摘要:
A disposable cartridge is provided for indicating the concentration of an analyte of interest in breath. The cartridge includes a housing having a side wall and a longitudinal axis, a reaction chamber in the housing, an optically transparent window in the side wall, for viewing contents of the reaction chamber, the window having a height measured in the direction of the longitudinal axis, and a liquid chamber in the housing. The cartridge is configured to display a color that extends along the entire height of the window following the transfer of liquid from the liquid chamber into the reaction chamber. The intensity of the color corresponds to a concentration of the analyte of interest in the reaction chamber.
