Important Information about
Using Alternative Sites Testing
• Alternative sites where you can test are dorsal hand, ventral palm, upper arm,
forearm, calf, and thigh.
• Under certain conditions, blood glucose test results obtained using samples taken
from your alternative sites may differ significantly from fingertip samples.
• The conditions in which these differences are more likely to occur is when your
blood glucose is changing rapidly such as following a meal, insulin dose, or physical
exercise.
• When blood glucose is changing rapidly, fingertip samples show these changes
more quickly than alternative sites samples.
• When your blood glucose is falling, testing with a fingertip sample may identify a
hypoglycemic (low blood sugar) level sooner than a test with an alternative site
sample.
• Use alternative sites samples only for testing prior to or more than two hours after a
meal, insulin doses, or physical exercise.
• Testing performed within two hours after meals, insulin doses, or physical exercise or
whenever you feel that your glucose levels may be changing rapidly should be done

from the fingertip.
• You should also use fingertip testing whenever you have a concern about hypogly-
cemia (insulin reactions) particularly if you suffer from hypoglycemic unawareness
(lack of symptom to indicate as insulin reaction), as forearm testing may fail to
detect hypoglycemia.
Test Results
The results are displayed on the meter as milligrams of glucose per deciliter of blood
(mg/dL). The meter displays results between 20~600mg/dL. If the test result is
below 20mg/dL, "Lo" will appear on the meter display. Consult with your healthcare
professional immediately on how to treat extremely low blood sugar (hypoglycemia).
If the test result is above 600mg/dL, "HI" will appear on the meter display. This
indicates extremely high blood sugar (hyperglycemia). Seek medical assistance
immediately.
IMPORTANT NOTE
Blood sugars may be altered by your food, physical activity, and/or stress.
