Do not insert the sensor in muscle or areas constrained by
clothing or accessories, areas with tough skin or scar tissue, sites
subjected to rigorous movement during exercise, or in sites under
a belt or on the waistline for best sensor performance and to avoid
accidental sensor removal.
Removing the sensor
When you are ready to change your sensor, disconnect the
transmitter from the sensor as described in your transmitter user
guide. Gently pull the sensor from your body to remove it. Place
the sensor in a sharps container.
Reagents
The sensor contains two biological reagents: glucose oxidase, and
human serum albumin (HSA). Glucose oxidase is derived from
Aspergillus niger and manufactured to meet industry requirements
for extraction and purification of enzymes for use in diagnostic,
immunodiagnostic, and biotechnical applications. The HSA used
on the sensor consists of purified and dried albumin fraction V,
derived from pasteurized human serum which is cross-linked
via glutaraldehyde. Approximately 3 μg of glucose oxidase and
approximately 10 μg of HSA are used to manufacture each sensor.
HSA is approved for IV infusion in humans at quantities much
larger than in the sensor.
Storage and handling
CAUTION: Do not freeze the sensor, or store it in direct
sunlight, extreme temperatures, or humidity. These conditions
may damage the sensor.
Only store sensors at room temperature between 36 °F to 80 °F
(2 °C to 27 °C).
Discard sensor after the “Use by date” indicated on the label, if the
package is damaged, or the seal is broken.
Sensor life of use
The sensor can be used one time, and it has a maximum life of
170 hours (seven days). The 170-hour life span of the sensor
begins when the sensor is connected to the transmitter.
