1. A method of estimating a blood analyte level using an optical coherence tomography (OCT) device, the method comprising:

  • receiving, from an OCT device, at least two OCT scans of an area of biological tissue along a depth dimension, the at least two OCT scans obtained at different times;

    computing intensity differences between the at least two OCT scans to generate an intensity difference plot;

    selecting, based on one or more portions of the intensity difference plot having large changes in intensity, corresponding one or more portions of the at least two OCT scans having large changes in intensity; and

    estimating a blood analyte level based on a comparison of the one or more portions of the at least two OCT scans with OCT calibration data.
