Abstract
A metabolite concentration is measured in vivo using Raman spectroscopy in such a way as to receive at a detector light scattered from the metabolite in interstitial fluid in skin in a measurement location at a depth of from 200-300 μm below the skin surface providing improved retention of correct calibration and transferability of calibration between individual subjects.
