It is generally recommended that a blood sample
for a blood glucose test performed at home is
taken from the fingertip. If you are not able to
take a blood sample from your fingertip, you
can also take one from another part of the body
(AST), such as the ball of the hand or lower arm
using the lancing device. g
In this case, exchange the protective cap on the
lancing device with the AST cap. After inserting
the lancet, put the transparent AST cap on the
lancing device instead of the protective cap and
tighten. Note that the AST cap is not intended to
be used for a blood sample from the fingertip.
We recommend, only to use the
alternative site testing (AST), when:
• at least 2 hours passed after the
last meal
• at least 2 hours passed after the
last intake of insulin and / or
exercise
Discuss the readings from an AST
measurement with your doctor, if:
• The glucose results are often
fluctuating
• The results do not match the way
you feel
In the case of low glucose (hypoglycemia),
the blood sample must be drawn from
the finger tip, as any changes in the blood
glucose level are quicker to detect from a
blood sample from the finger than from
any other part of the body.
The readings from a finger tip blood
sample and from another part of the body
can lead to the readings which radically
differ from one another. Therefore, always
consult your doctor before you perform a
blood glucose test using a blood sample
from another part of the body.
