1. A continuous analyte sensor system, the continuous analyte sensor system comprising:

  • a fluid coupler configured to operably connect with an IV equipment and with a vascular access device configured for communication with a vascular system of a host;

    a continuous analyte sensor located in at least one of a lumen of the fluid coupler or a lumen of the vascular access device, wherein the continuous analyte sensor is configured to measure a concentration of an analyte within the vascular system of the host; and

    a computer system operatively connected to the continuous analyte sensor, wherein the computer system is configured to receive analyte sensor data from the continuous analyte sensor, wherein the computer system is configured to process sensor data from the continuous analyte sensor by using information obtained prior to implantation, and wherein the computer system is configured to detect a change in sensitivity without requiring a reference analyte measurement;

    wherein the continuous analyte sensor system is configured to measure analyte concentration without requiring a reference analyte measurement for calibration performed after implantation of the continuous analyte sensor.
