TESTING USING BLOOD
SAMPLES
WARNING:
In order to limit the chance of an infection:
• Never share a lancet or lancing device with
others.
• Always use a new sterile lancet. Lancets are
single-use only.
• Ensure that you do not get any hand lotion, oil
or residual dirt in or on the lancets or lancing
device.
Preparing the lancing device for
a blood test
Follow the instructions on the package insert of the
lancing device for drawing a blood sample.
Preparing the puncture point
Stimulating blood perfusion by rubbing the
puncture point before taking a sample has a major
impact upon the test results. Blood extracted from
a point that you did not rub beforehand will return
a signicantly different value than a blood sample
extracted from a point you did rub in advance.
We recommend that you perform the following
steps before drawing a drop of blood:
• Wash and dry your hands before starting.
• Select a puncture point.
• Rub the puncture point for around 20 seconds
before inserting the lancet.
• Clean the puncture point with a cotton swab
moistened with a 70% alcohol solution and
allow your skin to air-dry.
• Testing using a ngertip (h)
Firmly press the lancing device against the
underneath part of your ngertip. Press the
release button to puncture your nger and the
device will click when the procedure is complete.
NOTE:
• Every time you test, use a different puncture
point. Repeatedly puncturing the same point
can cause a sore to form and callousing.
• We recommend that you wipe away the rst
blood drop, as it could contain tissue uid that
will affect the test results.
Performing a blood sugar test
In order to test your blood sugar levels, you require
the following: (b), (c), (e) and (f).
1. Insert a test strip into the meter’s test slot to
activate it
Wait until “
” and “ ” are displayed on the
meter.
2. Select the required meter mode by pressing
M.
3. Taking a blood sample (i)
Use the pre-set lancing device to puncture your
skin at the selected point. We recommend that
you wipe away the rst blood drop with a clean
tissue/cotton swab. The size of the blood drop
must be at least as large as (
actual size), which
equals around 0.5 microliter (µL) volume for a
blood sugar test and 0.8 microliter (µL) volume
for a β-ketone test. Carefully squeeze the area
around the puncture point to draw a further
blood drop. Take care NOT to smear out the
blood sample.
4. Apply the sample to the test strip (j)
Carefully allow the test strip to come into contact
with the blood drop at an angle. The control
window of the test strip will be sufciently full
once enough blood is applied. Do NOT take your
nger away before the device beeps.
