• A haematocrit value (proportion of red blood cells) between 20% and 60% has no significant influence
on the measurement results.
• A very high or low haematocrit value (proportion of red blood cells) may lead to incorrect
measurements. In the event of a very high haematocrit value (above 60%), the displayed blood
glucose value may be too low; in the event of a very low haematocrit value (below 20%), it may be
too high. Consult your GP if you do not know your haematocrit value.
• Do not use the test strips to measure blood glucose values on newborns.
• Do not use NaF or potassium oxalate anticoagulants to prepare for venous blood samples.
• Do not test any severely ill patients using this device.
• Use fresh whole blood only. Do not use serum or plasma.

Warning
• If the protective disc on a lancet needle has already been removed, do not use the lancet needle.
• If you drop the lancing device with an inserted lancet needle, carefully pick it up and dispose of the
lancet.
Important
• Use the lancing device only with lancet needles from the same manufacturer. Using other lancet
needles may prevent the lancing device from working properly.
• If you are using a third-party lancing device, please read the accompanying instructions for use.
5.1 Preparing to take a blood sample
1
Choose a part of the body from which to take a blood sample
Using the lancing device, you can take a blood sample from the fingertip. To make the procedure
as painless as possible, do not take samples directly from the centre of the fingertip, but
slightly to either side.
Warning
• In the event of suspected hypoglycaemia: take blood from the fingertip only. Reason:
changes to blood glucose levels can be detected quickly in blood samples taken from the
fingertip.
2
Prepare all parts
Prepare the following items: GL50 evo measuring device (A), test strip box or test strips in
film packaging (C) and sterile lancet needles (D).
Make sure that the ON/OFF switch is in the “ON” position.
3
Wash your hands
Wash your hands with soap and warm water before taking a blood sample. This not only
ensures optimal hygiene but also encourages good blood circulation at the puncture area on
the finger. Dry your hands carefully.
Warning
If you have used alcohol for cleaning, ensure that the area has fully dried prior to measuring.
Beurer GL50 evo 21
5.2 Preparing the lancing device for taking a sample
1
Remove the cap
Securely hold the monitor with one hand on the lancing device cover.
With your other hand, remove the cap from the monitor’s lancing device.
2
Insert the lancet needle
Insert a sterile lancet needle into the lancing device.
Note
Your starter set contains lancet needles in 2 dierent sizes. If you are
unable to take an adequate blood sample using the smaller needles
(purple, 33G), please use the slightly larger needles (blue, 28G).
Push firmly on the lancet until it audibly engages and it cannot be
pushed further into the holder.
3
Remove the protective lancet disc
Remove the protective lancet disc by bringing it into a horizontal position
and taking it o. Retain the protective disc for the safe disposal of the
used lancet needle after taking a blood sample.
4
Place the cap onto the lancing device. Make sure that the curved part
of the cap fits on the curved part of the lancing device. Press firmly on
the cap until it audibly engages.
5
Select the penetration depth
You can set seven dierent penetration depths on the lancing device
using the dial with printed numbers.
• 1 to 2: soft or thin skin
• 3 to 5: normal skin
• 6 to 7: thick or calloused skin
Turn the dial until the required bar is in the centre of the black marking.
6
Tension the lancing device
Pull back the slider in the direction of the arrow (on the image: to the
right) until it stops and then release. The slider automatically springs
back into position. The lancing device is now tensioned.
22 Beurer GL50 evo
5.3 Taking a blood sample and measuring the glucose level
Warning
• Change the puncture area each time you take a measurement, e.g. use a dierent finger or the other
hand. Repeatedly using the same area may cause inflammation or scarring.
• If the cap is not in place, there is a risk of injury from the exposed lancet.
• 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 measurement.
• Please note that insucient blood circulation at the puncture area, e.g. caused by cold temperatures
or illness, can lead to incorrect results.
Important
Do not apply any blood samples or control solutions to the test strip before inserting it in the monitor.
1
Prepare the test strip
Take a test strip from the box/film packaging and immediately close it again. Use the test strip
within three minutes of removal.
2
Insert test strip
Take the monitor in your left hand. Hold the monitor so
that the display is facing you.
Insert the test strip into the slot on the rear end of the
blood glucose monitor with the contacts first. Make sure
that the front of the test strip is facing you. You can touch
any part of the test strip with clean, dry hands.
3
The device switches on automatically
After you have inserted the test strip, the blood glucose
monitor switches on automatically and the Beurer logo,
the date and the time are briefly displayed.
The measuring device is ready to measure as soon as
the test strip animation is displayed.
Important
If segments of the display are missing, stop using the
device and immediately contact Customer Services.
Beurer GL50 evo 23
4
Lancing to take a blood sample
The lancing device can now be used to take a blood
sample. Make sure that the blood remains as a droplet
and is not spread.
Blood sample from the fingertip
Firmly position the lancing device slightly to the side of
the centre of the fingertip. Press the trigger. Remove the
lancing device from the finger. A round drop of blood of
at least 0.6 microlitres (corresponds to approx. 1.4 mm
in diameter, original size: ) must have formed.
Please also note the following:
• If the blood glucose test results do not match how you feel, carry out another test using blood
from your fingertip.
• DO NOT change your treatment purely on the basis of a measurement that was carried out
using blood taken from an alternative area. Carry out another test with blood from your fingertip
in order to confirm the test result.
• If you often fail to notice that you have a low blood glucose level, carry out a test using blood
from your fingertip.
5
If necessary, repeat the lancing process
If you do not obtain sucient blood, repeat the lancing process with a greater penetration
depth in a dierent area.
6
Apply blood to the test strip
Turn the monitor by 180°. Hold the blood input gap
(at the tip of the test strip) to the drops of blood until the
gap is completely filled and the monitor in the display
starts counting backwards.
Do not press the penetration area to the test strip.
The blood must not be spread. The blood is sucked into
the gap.
OK
Note
Error message “Error 2” appears on the display if the gap was not correctly and suciently filled
with blood. Repeat the measurement using a new test strip and a greater penetration depth.
24 Beurer GL50 evo
Note
• Do not apply blood to the sides of the test strips
• Do not add blood later if the device does not start measurement. Remove the test strip and end this
test. Use a new test strip.
• If the test strip has already been inserted into the device but no blood is added to the test strip within
two minutes, the device switches itself o. Briefly remove the test strip and reinsert it so that the
device automatically switches itself back on.
• Contact Customer Services if you are unable to fill the test strip with blood correctly.
5.4 Reading the result and marking measurements
Reading the result
As soon as the blood input gap is filled with sucient
blood, the device performs the blood glucose
measurement. The monitor counts down for approx. five
seconds. The measurement is then shown on the display.
MEMORY
MEMORY
Read your measured value. Check again that you have read the result correctly. The underline must
be below the measured value, otherwise you need to turn the monitor by 180°. For explanations of
and measures regarding the measured values, see “5.6 Evaluating measured blood glucose values”
on page 26. If an error message is displayed, read chapter “8. What if there are problems?” on
page 34.
Marking the measurement
You have the following options for marking measured values:
ONo marking
Before meal
After meal
General marking (e.g. after exercising).
Marking measured values enables you, your GP or diabetes consultant to better monitor your blood
glucose values. For example, you can display the average values of all measurements taken before
a meal.

5.6 Evaluating measured blood glucose values
Your blood glucose monitor can process measured values between 20 and 630 mg/dL (1.1 and
35.0 mmol/L). A warning message is displayed in the event of measured values lower than 20 mg/dL
(1.1 mmol/L) and measured values higher than 630 mg/dL (35.0 mmol/L).
Warning
• If you suspect that the blood glucose results are incorrect, first repeat the test and, if necessary,
perform a functional test using control solution. Seek medical advice if dubious results persist.
• Seek medical attention immediately if your symptoms do not correspond to your measured blood
glucose values and you have followed all instructions for the Beurer GL50 evo blood glucose monitor.
• Do not ignore symptoms of too high/low blood glucose levels. Always seek medical attention!

5.7 Functional check using control solution
The control solution is used to test the entire blood glucose monitoring system. This helps to determine
whether the monitor and the test strips are working optimally together and whether the test is being
performed correctly.
Perform the control solution test if you suspect that the blood glucose monitor and/or the test strips
could be faulty or if you have repeatedly measured unusual blood glucose values. Also test the monitor
if it has been dropped or is damaged. The control solution is available separately. For the control
solution test, please observe the additional notes in the instructions for use for the control solution.
Important
• Do not use third-party control solution. Correct functioning of your monitor can only be tested using
Beurer LEVEL3 + LEVEL4 control solutions.
• Control solution measurements: when using the device, specialist personnel must follow statutory
guidelines.
• Do not apply any blood samples or control solutions to the test strip before inserting it in the monitor.
Performing a functional test using control solution
Warning
To obtain correct results, the measuring device, the test strip and the control solution must be the
same temperature. For the “Functional test using the control solution”, the temperature is to be
between 20°C and 26°C.
1
Insert test strip
Hold the monitor so that the display is facing you. Insert a test strip into the slot on the monitor
with the contacts first. Make sure that the front of the test strip is facing you (see section “3.5
Test strips”).
Beurer GL50 evo 29
2
Activate control mode
Once you have inserted the test strip, the blood glucose monitor
switches on automatically and briefly shows the initial display. Once
the initial display has disappeared, quickly rotate the scroll wheel all
the way from the left to the right until “CONTROL” appears at the top
of the animation display.
IMPORTANT: Control solutions and blood react to temperature influences in dierent ways.
It is therefore of vital importance that control solution measurement is always performed in
control solution mode. If this mode is not used, results may be obtained that are outside the
target range.
3
Drip control solution on surface
Choose a clean surface to carry out the functional test
correctly. Shake the control solution well before use. Undo the
cap and squeeze two drops next to each other on the clean
surface without touching them. Use the second drop for the
measurement.
Note
Never apply the control solution straight from the bottle to a test strip. Reason: the remaining
solution in the bottle will be contaminated if the top of the bottle comes into contact with the
test strip.
4
Apply drop to the test strip
Hold the input gap (at the tip of the test strip) to the drop of control solution until the gap
is completely filled. When the gap is suciently filled with solution, the device performs a
measurement. The device counts down for approx. five seconds. The measurement is then
shown on the display.
5
Evaluate result of functional test
Check whether the result is within the specified range of results for the control solution. This
range of results is printed on the test strip box or the test strip packaging or on the information
sheet included.
Expected results
At room temperature, the measured values from the test using the control solution should be within
the range printed on the test strip box in approx. 95% of all tests.
Warning
The result range printed on the test strip box applies only to the control solution. This is not a
recommended value for your blood glucose level.
30 Beurer GL50 evo
If measurements are outside the specified range, check the following possible causes:
Cause Action
• The first drop of control solution was not
disposed of.
• The tip of the bottle was not cleaned correctly.
• The bottle was not shaken well enough.
Rectify the cause and repeat the test.
Control solution or test strip is contaminated.
Repeat the test using a new bottle of control
solution and/or new test strip.
The control solution, test strip or blood glucose
monitor is too warm or too cold.
Bring the control solution, test strip and monitor
to room temperature (+20°C to +26°C) and
repeat the test. The check performed at room
temperature is used as a general functional
check. The operating range specified in
the technical specifications is valid without
restriction.
The test strips and control solution were kept
at a temperature and humidity outside the
specified range.
Repeat the test using new, correctly stored
accessories (test strips and control solution).
Damaged test strips. Possible causes include
• Test strips were exposed to fresh air for too
long.
• The test strip box was not closed completely.
Repeat the test using a new test strip and/or a
new box of correctly stored test strips.
Test strip or control solution has expired.
Repeat the test using a new bottle of control
solution and/or new test strip from a new box.
Functional test using control solution was
performed incorrectly.
Repeat the test and follow the instructions.

Test strip functionality
Test strips enable a quantitative measurement of the glucose level in fresh whole blood (capillary or
venous). When the gap for taking blood comes into contact with a drop of blood, it is automatically
filled by simple capillary action. The blood is sucked into the absorbing gap on the test strip and the
monitor measures the glucose level in the blood.
The test is based on the measurement of an electric current that is generated by the chemical reaction
of the glucose with the enzyme glucose dehydrogenase (Aspergillus oryzae) on the strip.
Beurer GL50 evo 37
During the reaction, a mediator transports electrons through the electrode surface and so generates
a current.
The monitor analyses this current. The current flow is proportional to the glucose content in the blood
sample. The results are shown on the blood glucose monitor display. Only a small amount of blood
is required (0.6 microlitres) and measurement takes approx. 5 seconds. The test strip detects blood
glucose values from 20 to 630 mg/dL.
Chemical components of the test strip sensor
• FAD glucose dehydrogenase 6%
• Potassium ferricyanide 56%
• Non-reactive components 38%
Control solution functionality
The control solution contains a fixed amount of glucose that reacts with the test strip. A test with
control solution is similar to a blood test. However, control solution is used instead of blood. The
measurement using control solution must be within the result range. This range is printed on each
test strip box.
Chemical composition of the control solution
The control solution is a red solution with the following D-glucose level (in percentage shares).
Substances LEVEL 3 control solution LEVEL 4 control solution
D-glucose 0.14% 0.37%
Non-reactive components 99.86% 99.63%
