Testing blood glucose

Notes
Use a new lancet each time you obtain blood. This not only
reduces the risk of infection but also helps ensure virtually pain-
free blood sampling.
Do not prime the finger pricker until you are ready to collect
blood. Keeping the finger pricker in this primed state can cause
parts to become misshapen through tension, impairing its opera-
tion.
i
The amount of blood that emerges at the puncture site depends
on the penetration setting and the pressure used to hold the fin-
ger pricker against the skin. If the amount of blood you obtain is
too small, try again, applying more pressure this time. If you still
obtain insufficient blood, repeat the procedure with progressively
deeper settings. If too much blood emerges, reduce the penetra-
tion depth.
