1. A method for performing optical coherence tomography measurements to determine an analyte level in tissue, comprising:

  • aligning an optical coherence tomography system to a tissue region of a subject through an optical coupler, wherein the tissue region includes at least a first tissue site and a second tissue site, and wherein the first and second tissue sites comprise spatially distinct two-dimensional regions of a skin surface of the subject;

    scanning, by a scanner of the optical coherence tomography system, a beam over the first tissue site using the optical coupler to collect a first set of optical coherence tomography measurements;

    scanning, by the scanner of the optical coherence tomography system, the beam over the second tissue site using the optical coupler to collect a second set of optical coherence tomography measurements;

    determining, by a processor of the optical coherence tomography system, based on the first set of optical coherence tomography measurements, that the first tissue site is an analyte correlating region, wherein an analyte correlating region comprises a tissue site that is valid for measuring an analyte level;

    determining, by the processor of the optical coherence tomography system, based on the second set of optical coherence tomography measurements, that the second tissue site is not an analyte correlating region and not valid for measuring an analyte level; and

    monitoring, by the processor of the optical coherence tomography system, the analyte level by at least;

    causing the scanner to monitor the first tissue site and processing optical coherence tomography measurements associated with the first tissue site to measure the analyte level; and

    causing the scanner to not monitor and not processing optical coherence tomography measurements associated with the second tissue site.
