[Determination of glucose in exhaled breath and saliva by ion chromatography].

A novel noninasive method was developed for determining glucose levels in human exhaled breath and saliva using ion chromatography. This innovative approach involves collecting exhaled breath and saliva samples using a self-designed condensation device and non-stimulative method to ensure minimal participant discomfort. The glucose contents in both exhaled breath condensate (EBC) and saliva were analyzed using ion chromatography, which is highly sensitive and specific.
