What to Know Before You Apply the Sensor
• The Sensor Pack and Sensor Applicator
are packaged as a set and have the
same Sensor code. Check that the
Sensor codes match before using your
Sensor Pack and Sensor Applicator.
Do NOT use Sensor Packs and Sensor
Applicators with different Sensor codes
together as this will result in incorrect
glucose readings.
• Wash the application site on the back of your upper arm using a
plain soap, dry, and then clean with an alcohol wipe. This will help
remove any oily residue that may prevent the Sensor from sticking
properly. Allow site to air dry before proceeding. Carefully preparing
the site according to these instructions will help the Sensor stay on
your body for the full 14 day wear period and help prevent it from
falling off early.
• Clean hands prior to Sensor handling/insertion to help prevent
infection.
• Change the application site for the next Sensor application to
prevent discomfort or skin irritation.
• Only apply the Sensor to the back of the upper arm. If placed in
other areas, the Sensor may not function properly.
• Select an appropriate Sensor site to help the Sensor stay attached
to the body and prevent discomfort or skin irritation. Avoid areas
with scars, moles, stretch marks, or lumps. Select an area of skin
that generally stays flat during normal daily activities (no bending or
folding). Choose a site that is at least 1 inch away from an insulin
injection site.
When is Sensor Glucose Different from Blood Glucose
• Physiological differences between the interstitial fluid and capillary
blood may result in differences in glucose readings between the
Sensor and results from a fingerstick test using a blood glucose
meter. Differences in glucose readings between interstitial fluid and
capillary blood may be observed during times of rapid change in
blood glucose, such as after eating, dosing insulin, or exercising.
