1. A method comprising:

  • receiving, from an optical coherence tomography apparatus, an intensity data measurement for a region of tissue;

    passing the intensity data measurement through a first frequency band filter having a first bandwidth to produce a first output;

    passing the intensity data measurement through a second frequency band filter having a second bandwidth that is wider than the first bandwidth to produce a second output;

    determining, by a processor, an indication of fluid flow in the region of tissue by comparing the first output and the second output; and

    in response to determining a positive indication of fluid flow in the region of tissue, determining, by the processor, a blood analyte measurement based on at least some of the intensity data measurement.
