1. A non-invasive, portable glucose monitoring device comprising:

  • a) at least one collection reservoir for collecting at least one exhaled breath sample, wherein said collection reservoir comprises a sensor and a signaling means, said sensor, said signaling means or both either comprising or being in operative communication with at least one processor; and

    b) a means for extracting condensates from the exhaled breath sample, wherein said sensor is equipped to identify glucose and at least one solute in the extracted condensate, and where the concentration of said at least one solute, the concentration of which is both tightly regulated in blood and which concentration is substantially identical in airway lining fluid to that in blood, is used by said processor as a ratio with the concentration of that same solute in blood to determine a dilution factor to be utilized in correlating the concentration of glucose in blood with the glucose identified in the extracted condensate by multiplying said dilution factor with the concentration of glucose in said condensate.
