When you see the symbol during the fi rst 12 hours of wearing a Sensor, this is a reminder
that your body might still be getting used to the new Sensor. Confi rm Sensor glucose readings with a blood glucose test before making treatment decisions.

Before breakfast
Lisa sees:
the †
because she placed
her sensor 11 hours
ago, before going to
bed. The trend arrow
is pointing diagonally
down.
Lisa:
performs a
blood glucose check
with the built-in test
strip port before
deciding how many
carbs to eat. She
could consider taking
a little less insulin
since glucose is
falling.
Before lunch
Lisa sees:
the
trend arrow is
pointing diagonally
up, indicating that
her glucose is rising.
Lisa:
takes enough
insulin to cover
the meal, and a
little more, since
the trend arrow is
pointing upwards.
After lunch
Lisa sees:
her
glucose is high,
but trend arrow is
pointing diagonally
down, indicating
glucose could
decrease
15-30 mg/dL in
the next 30 minutes.
Lisa:
does not take
a correction dose as
it is within 2 hours of
her meal dose and
the trend arrow is
pointing downward.
This could result in
“insulin stacking” and
low glucose. Lisa sets
a reminder to scan
again in 30 minutes.
Before sleep
Lisa sees:
her
glucose is in range
but the trend arrow
is pointing down.
She remembers that
she ate less than
usual at dinner.
Lisa:
eats half a
sandwich prior to
getting ready for
bed and will scan
again before turning
off her light.
After breakfast
Lisa sees:
the trend
arrow pointing
diagonally up,
indicating her
glucose could rise
15-30 mg/dL in the
next 30 minutes.
Lisa:
takes no
action at this time
and decides she will
scan again later
because it is normal
for her glucose to
rise after a meal.
Before exercise
Lisa sees:
her
glucose is in range,
however the trend
arrow is pointing
diagonally down,
which indicates
her glucose could
decrease between
15 and 30 mg/dL in
the next 30 minutes.
Lisa:
decides to
take a snack with
her for her daily,
30-minute walk, in
case her glucose
goes low. She also
remembers to bring
her reader so that
she can scan again.
