Analyte sensors with modified calibration

An analyte monitoring kit comprising:

• a package;
• a plurality of analyte monitoring devices that are separately sealed in the package and configured to be accessed independently from one another;
• and
• a code or tag provided on or in the package that is separable from the package;
• wherein each of the plurality of analyte monitoring devices comprises a sensor, and where all of the sensors provided in the analyte monitoring kit were fabricated on a same substrate using substantially uniform processes and assembled to their respective analyte monitoring devices without the respective sensors being individually calibrated;
• wherein a further representative sensor fabricated together with all of the sensors provided in the analyte monitoring kit on the same substrate using the substantially uniform processes is tested to determine a first sensitivity, and wherein the first sensitivity is associated with the code or tag, such that the code or tag is configured to be utilized by the patient to automatically apply the first sensitivity to the sensors of each of the plurality of analyte monitoring devices provided in the kit.
