Preparing to test and testing
Preparing to test
1 Have the test strip container close by.
2 Make sure the code chip associated with that lot of test strips
is inserted in the monitor.
Prepare the lancing device by inserting a fresh lancet.
Do not prick your finger until asked to do so.
The CoaguChek Softclix lancing device is intended only for
patient self-monitoring by a single person.
It must not be
used to collect blood in a multi-patient setting as it
does not incorporate any features to guard against
cross-infection
.

1 Wash your hands with soap and warm water. Dry them
thoroughly.
Residues of water on the skin can dilute the drop of blood
and so produce false results.
2 Place the monitor on a level, vibration-free surface or
hold it
in your hand so it is roughly horizontal
. Turn the monitor on
by pressing the On/Off button .
3 Check that all of the display segments are functioning and that
the date and time are correctly set.
Note:
An explanation for each symbol appearing on the display is
given at the end of this Quick Reference Guide.

4 The flashing test strip symbol prompts you to insert a test strip.
Remove a test strip from its container.
Close the container again with the stopper immedi-
ately after removing the test strip. Leaving the con-
tainer open for a longer period of time may destroy
the strip and create error messages.
5 Slide the strip in as far as it will go (in the direction indicated
by the arrows). A beep tone indicates that the monitor has
detected the test strip (providing the beep tone is turned on in
the settings).

6 The code number of the code chip inserted in the monitor
flashes in the display. Make sure that this number is identical
with the code number printed on the test strip container. If the
two numbers are identical, confirm by pressing the
M
button.
7 The hourglass symbol shows that the test strip is warming up.
When this process is complete, you may apply the drop of blood.
8 The blood drop symbol and the application area flash to indi-
cate that the monitor is ready to test. At the same time a 120-
second countdown begins. Within this time you must have
applied the drop of blood to the test strip, otherwise you
receive an error message

9 Now prick the side of a fingertip with the lancing device. Stroke
the lanced finger until a drop of blood is formed. Do not press
or squeeze the finger.
Apply the first drop of blood from the finger.
10 Apply the blood directly from the finger to the semicircular,
transparent sample application area of the test strip. Alterna-
tively, you can touch the blood drop against the side of the
sample application area (instead of applying it to the centre
from above). The test strip draws up the blood by capillary
action. During this process you must hold the blood drop to the
test strip until the flashing blood drop symbol disappears and
the monitor beeps (providing the beep tone is turned on).
Apply the blood drop to the test strip
within 15 seconds
of
pricking the fingertip.

11 When you have applied enough blood, the blood drop symbol
disappears and measurement starts.
Do not add more blood. Do not touch the test strip until
the result is displayed.
12 Following a successful outcome of the automatic quality con-
trol check (“QC” is shown with a tick after it), the actual test
begins. The hourglass flashes until the monitor has the result.

13 The result is displayed in your chosen unit, and is automatically
saved. Enter the test result in your patient logbook.
14 Remove the test strip from the measurement chamber and turn
the monitor off.
A “c” is displayed along with the result.
This may occur if the haematocrit value is very low or due to
erroneous blood collection (e.g. wet hands). Repeat the measure-
ment and make sure that your hands are dry. If the message persists,
please contact your healthcare professional for a haematocrit check.
