A prediction scheme of the glucose level involving a set of probe wavelengths belonging to the visible and infrared bands is proposed and verified. These discrete wavelengths were selected because the correlation between the glucose level and the optical reflection or transmission for an aqueous glucose solution was sufficiently high. The glucose level was predicted by means of the partial least squares algorithm. The standard error of calibration and the standard error of prediction were tested to assess the proposed method. The demonstrated standard errors of prediction for the cases involving the reflection response for a set of probe wavelengths (410, 550, 780, 950, and 960 nm) and the transmission response for another set of probe wavelengths (960, 1060, 1150, 1330, 1630 nm) were 2.8 and 1.5, respectively, which were approximately comparable to those of the conventional case resorting to a continuous wide spectral band. © 2011 Wiley Periodicals, Inc.
