Serum and Blood Glucose

In principle, serum or blood glucose may be quantified either by using MIR spectroscopy or by exploiting any of three sets of NIR absorptions, namely those corresponding to vibrational combination bands (2000-2500 nm), the first overtone absorptions (1400-1800 nm), or the second overtone bands (950-1250nm). All of these have been explored in attempting to quantitate serum glucose,

To summarize the present state of the art the most accurate NIR analysis of serum glucose, carried out using the spectral window and transmission path length optimal for NIR detection, approaches the level of accuracy required for clinical use and the NIR detection of glucose in blood is less accurate, mainly due to the confounding influence of fight scattering by the blood cells.
