    Abstract: The present invention relates to a system and method for improving glucose sensor accuracy by utilizing multiple calibration methods and selecting the most accurate method depending on a consensus glucose concentration estimate. Embodiments of the present invention comprise the steps of performing at least one in vivo update of surrounding glucose to acquire glucose values; calculating multiple updated calibration estimates using the updated glucose values; calculating an initial consensus glucose estimate from sensor output using each updated calibration estimate; applying a smooth crossover function to the multiple calibration estimates based on the value of the initial consensus glucose estimate; and adding weights to the multiple calibration estimates to acquire a consensus glucose estimate.

    Abstract: A system and method are provided for utilizing radiometric fluorescence detection to determine a glucose independent concentration value when measuring frequency bands that do not contain the system isosbestic point. Preferably two bands are chosen such that a first band is below the system isosbestic point, and a second band is above the system isosbestic point, and both points are sufficiently far from the frequency endpoints to maximize the signal to noise ratio.
