1. A system for monitoring a glucose concentration in a host, the system comprising:

  • a continuous glucose sensor configured to produce a signal indicative of a glucose concentration in a host;

    monitoring system electronics operably connected to the sensor and configured to receive reference data from a single point glucose measuring device, the single point glucose measuring device configured to receive a biological sample from the host and to measure a concentration of glucose in the biological sample, wherein the reference data is indicative of a measured glucose concentration in the biological sample, wherein the monitoring system electronics are configured to provide real-time calibrated glucose concentration values of the host based on the signal, and wherein providing the real-time calibrated glucose concentration values comprises evaluating an acceptability of the reference data in real time using a clinical acceptability grid, and calibrating or confirming the signal responsive to the acceptability evaluation of the reference data.
