Paper Abstract
We have been developing a new technique for measuring urine glucose concentration using near infrared spectroscopy
(NIRS) in conjunction with the Partial Least Square (PLS) method. In the previous study, we reported some results of
preliminary experiments for assessing feasibility of this method using a FT-IR spectrometer. In this study, considering
practicability of the system, a flow-through cell with the optical path length of 10 mm was newly introduced. Accuracy
of the system was verified by the preliminary experiments using urine samples. From the results obtained, it was clearly
demonstrated that the present method had a capability of predicting individual urine glucose level with reasonable
accuracy (the minimum value of standard error of prediction: SEP = 22.3 mg/dl) and appeared to be a useful means for
long-term home health care. However, mean value of SEP obtained by the urine samples from ten subjects was not
satisfactorily low (53.7 mg/dl). For improving the accuracy, (1) mechanical stability of the optical system should be
improved, (2) the method for normalizing the spectrum should be reconsidered, and (3) the number of subject should be
increased.
