A single detector infrared ATR glucose measurement system is disclosed
herein. The device uses attenuated total reflection infrared
spectroscopy. Preferably, the device is used on a fingertip and compares
two specific regions of a measured infrared spectrum to determine the
blood glucose level of the user. A single IR detector is utilized along
with an alternating filter. This device is especially suitable for
monitoring glucose levels in the human body, and is especially beneficial
to users having diabetes mellitus. The device and procedure may be used
for other analyte materials which exhibit unique mid-IR signatures of the
type described herein and that are found in appropriate regions of the
outer skin.
