Performing a Blood Glucose Test From an Alternate Site
Consider AST when:
Use fingertip testing:
• Testing before a meal.
• Within two hours after a
meal.
• You are in a fasting state.
• Within two hours after insulin
dosing.
• Two hours have passed
• Within two hours after
since a meal.
physical activity.
• Two hours have passed
• If you have a history of
since insulin dosing.
hypoglycemia, are
experiencing low blood
• Two hours have passed
glucose, or suffer from
since physical activity.
hypoglycemic unawareness
(you cannot tell when you
have low blood glucose).
• To confirm your blood
glucose level if your AST
result is not consistent
with how you feel.
• During times of stress or
illness.
Step 1
Choose a Site: Select a soft,
fleshy area on the palm that is
free of visible veins and moles
and away from bone. Wash the
area with warm, soapy water.
Rinse and dry completely. If you
use alcohol wipes to cleanse
the site, make sure the area is
dry before lancing the site.
Step 2
Insert lancet and cock
lancing device.
Step 3
Remove test strip from the
bottle. Immediately replace
the bottle cap tightly. Insert
test strip as shown in diagram.
A beep will sound and the
meter will turn on automatically.
Verify that all symbols appear
on the screen.
Verify that the code number
displayed on the screen
matches the code number on
Code No.

Step 4
a) PRESS AND VIGOROUSLY RUB THE SELECTED
AREA for 10 SECONDS until it starts to feel
warm to the touch.
b) Firmly hold the cocked lancing device
b
against the clean skin for 5-10 seconds.
c) Press the release button
on the lancing device
to lance the skin. Continue
to hold the lancing device
firmly against the skin until
a blood drop forms.
d) Once a large enough drop of blood has
formed, remove the lancing device.

d
Repeat blood draw if fluid is clear.
Step 5
Pick up the meter. Touch the end of the test strip
to the blood sample until the reaction site is full.
Immediately remove the meter and test strip from
the blood drop.
NOTE
If it took longer than 20 SECONDS to
obtain a blood sample and touch the
strip to the blood drop, repeat test.
IMPORTANT
• Was the sample free of clear or watery fluid?
• Was the drop large enough (at least 0.3 µL)?
• Did the reaction site fill with enough blood all at once?
IF NOT,
REPEAT TEST.
Step 6
The meter will count down and display result in 7 seconds.
CONSIDER YOUR RESULT.
REPEAT ALTERNATE SITE TEST:
• IF the blood sample appeared to be diluted with clear fluid.
• IF you did not vigorously rub the test site.
• IF the blood drop was not large enough to fill the reaction site
• IF the test was accidentally marked as a "Control" result.
• IF your result was not consistent with how you feel.
• IF more than 20 seconds elapsed from sample collection to
a
measurement (evaporation of the blood sample may cause
a test result that is higher than the actual value).
Any of the above situations can lead to an inaccurate test result.
If the repeated alternate site result is still not consistent with how you
feel, confirm your blood glucose level with fingertip testing.
Step 7
Always record your results in your self-testing logbook along with
other information such as insulin dosage, diet, and exercise.
The result is automatically stored in memory with the time and date.

Step 8
Remove the test strip and dispose of it in accordance with local
guidelines or as directed by your healthcare professional.
The meter shuts off automatically when the test strip is removed.
