Preparing the Puncture Site
Rubbing the puncture site before blood extraction has a significant
influence on the accuracy of your test results.
Blood from an alternate site that has not been rubbed exhibits a
measurably different glucose concentration than blood from the finger.
When the puncture site was rubbed prior to blood extraction, the test
result will be more precise.
Please follow the suggestions below before obtaining a drop of
blood:
Wash and dry your hands before starting.
Select the puncture site either at fingertips or another body parts
(please see section "Alternative Site Testing" (AST) on how to select
the appropriate sites).
Rub the puncture site for about 20 seconds before penetration.
Clean the puncture site using cotton moistened with 70% alcohol
and let it air dry.
NOTE:
Choose a different spot each time you test. Repeated punctures at the same
spot may cause soreness and calluses.
It is recommended that you discard the first drop of blood as it might contain
tissue fluid, which may affect the test result.
Fingertip testing
Hold the lancing device firmly against
the lower side of the fingertip. Press the
release button to puncture the finger;
you will hear a click indicating that the
puncture is complete.
