A method for noninvasively measuring blood concentration of a substance, such as, for example, blood glucose levels, is described herein. The method may comprise measuring an initial absorption data using near infrared spectroscopy (NIR), and obtaining a second set of absorption data. The initial absorption data, along with the second set of absorption data, may then be adjusted by applying a convolution function and a Monte Carlo simulation to the raw data. In a step, an initial estimate of the level of the substance in the blood, such as, for example, initial blood glucose level, may be calculated based on the adjusted data and pulse oximetry information using a mixing model equation. |
