Testing blood glucose 3
In rare instances bruising may occur following
collection of blood from alternate sites.
If the result obtained using blood taken from the
palm, forearm, the upper arm, the calf or the
thigh produces a result that does not agree with
the way you feel, test again with blood collected
from a fingertip. If the test result still does not
agree with the way you feel, please contact your
healthcare professional.
do not change your treatment based only on a
single result.
only use the Accu-Chek FastClix Mobile AST cap
in conjunction with the Accu-Chek FastClix
Mobile lancing device.
using the AST cap with a different lancing de-
vice or using a different AST cap with the lan-
cing device can result in damage to the lancing
device and/or the AST cap or prevent them from
functioning properly.

The success of obtaining a suitably sized drop of
blood from alternate sites may differ from per-
son to person and from site to site.
The right moment
Before you test with blood collected from the palm,
forearm, the upper arm, the calf or the thigh, be aware
of the following limitations: Capillary blood in the
fingertip responds more quickly to changes in blood
glucose levels than blood at alternate sites due to
higher concentration of blood vessels. Blood glucose
values obtained from blood taken from alternate sites
may therefore differ from values obtained from blood
taken from the fingertip.
do not test blood from the palm, forearm, the upper
arm, the calf and the thigh:
up to two hours following a meal, when blood glu-
cose values can change quickly
after exercise
if you have a temperature or a medical condition
limiting your mobility or if you are confined to bed
if you suspect that your blood glucose is extremely
low (hypoglycemia)
if you know that you sometimes do not notice when
you are hypoglycemic
during peak action time of short-acting insulin (up to
approximately 4 hours after the injection) or rapid-
acting insulin analogues (up to approximately 2
hours after the injection)
