Testing blood glucose 3

Obtaining a blood drop

Use a new lancet each time you obtain blood.

This reduces the risk of infection and helps

ensure virtually pain-free blood sampling.

In general, all the ngers are suitable for obtaining

blood. Certain ngers can be unsuitable if, for example,

a skin or ngernail infection is present. We recommend

obtaining capillary blood from the side of a ngertip as

this registers the least pain (see black areas in the

illustration on the left).

The amount of blood that emerges at the puncture site

depends on the penetration depth setting and the

pressure used to hold the lancing device against the

skin.

If you nd that the amount of blood for a test is



insufcient, press the lancing device more rmly

against the skin next time. If you still obtain insuf-

cient blood, also increase the penetration depth one

setting at a time when you perform your next tests.

If, on the other hand, you obtain too much blood,



reduce the penetration depth next time.
