5 Measuring blood glucose values Warning • If the protective disc on a lancet needle has already been removed, do not use the lancet needle. • If you have dropped the lancing aid with an inserted lancet needle, carefully pick it up and dispose of the lancet. Important • Use the lancing aid only with lancet needles by the same manufacturer. The use of other lancet needles may impede the functionality of the lancing aid.
5.2 Taking a blood sample Warning • Change the puncture area for each measurement, e.g. a different finger or the other hand. Repeatedly using the same area may cause inflammation, numbness or scarring. • Without the cap, there is a danger of injury from the exposed lancet. • Do not use the AST cap to take blood samples from the finger. • Do not squeeze your finger to obtain a larger drop of blood. If squeezed, the blood is diluted with tissue fluid and this may lead to an incorrect measuring result.
5 Setting the penetration depth You can set seven different penetration depths on the lancing device. The penetration depth is displayed by the markings in the cap. • soft or thin skin • normal skin • thick or callous skin Turn the moving upper part of the cap until the desired penetration depth is displayed. Note When using the AST cap, penetration depth does not need to be set. 6 Pull the tensioning device back until it audibly engages. Release the tensioning device.
12 You may now use the lancing aid to take a blood sample. Please ensure that the blood remains a droplet and is not spread. Immediately use the blood droplet to take a measurement.
