Method and apparatus for non-invasively determining glucose level in fluid of subject, typically blood glucose level. Impedance of skin tissue is measured and the measurement is used with impedance measurements previously correlated with directly determined glucose levels to determine the glucose level from the newly measured impedance. It is thus possible, to routinely non-invasively determine fluid glucose levels.
Cette invention a trait à une technique et à l'appareil correspondant permettant de déterminer de manière non effractive le taux de glucose dans les liquides organiques d'un sujet et, notamment, le taux de glucose sanguin. On mesure l'impédance du tissu cutané et l'on utilise cette mesure avec des mesures d'impédance précédemment mises en corrélation avec des taux de glucose directement établis, ce qui permet de déterminer le taux de glucose à partir de l'impédance venant d'être mesurée. Il est, de ce fait, possible de déterminer des taux de glucose d'un liquide de manière non effractive et routinière.
