Patent ID: 7927274

Claim:
A system for monitoring a glucose concentration in a biological sample in a host, the system comprising: a continuous glucose sensor configured to produce sensor data indicative of a glucose concentration in a host, wherein the glucose sensor comprises a sensing membrane comprising an enzyme domain; and a receiver unit adapted to receive the sensor data from the continuous glucose sensor, wherein the receiver unit comprises a housing, and wherein the receiver unit comprises: a single point glucose monitor physically connected to the housing, wherein the single point glucose monitor is configured to produce a glucose concentration measurement from a biological sample obtained from a host, wherein the glucose monitor comprises a sensing membrane comprising an enzyme domain, wherein the receiver unit is configured to calibrate the sensor data from the continuous glucose sensor using the glucose concentration measurement from the single point glucose monitor, and wherein the enzyme domain of the sensing membrane of the continuous glucose sensor and the enzyme domain of the sensing membrane of the single point glucose monitor are substantially the same.
