The kit uses an improved 5,5'-dithiobis(2-nitrobenzoic acid) (DTNB) method that combines deproteination and detection into a single reagent, with DTNB reacting with reduced glutathione to form a yellow product
Both compounds affect gastrointestinal function, which means combination protocols require careful monitoring and management strategies
Hundreds of different volatile organic compounds can be detected in exhaled breath 27 , and VOCs in exhaled breath are analyzed mainly by technologies based on mass spectrometry or on sensor arrays such as the electronic nose (e-NOSE) 23,28 Currently, gas chromatography coupled with mass spectrometry (GC/MS) is one of the most suitable techniques because it enables VOC identification in exhaled breath samples with high sensitivity in the ppb range 29
