2 SAFETY INFORMATION AND WARNINGS
Risk of infection
All components of the measuring device and accessories may come into contact
with human blood, and are therefore a possible source of infection.
WARNING
x This measuring device must display the blood sugar content in
mmol/L. The unit of measure mmol/L follows the blood su gar value. If
your device does not display mmol/L, contact customer ser vices immediately. You risk damaging your health if you perform a blood sugar measurement using an unfamiliar unit of measure, since values
may be interpreted incorrectly and cause the wrong corrective measures to be taken.
x This measuring device must only be used by one person. There is a risk of
infection if the same device is used by more than one person.
x The lancing device is intended for self-testing. Never share the lancing
device or needle lancet with another person (risk of infection).
x Use a new sterile needle lancet for each blood sample (for single use only).
Measuring
WARNING
x The measured values you determine are useful for information purposes
only – they are not intended to replace consultation with your doctor. Discuss your blood sugar values with your doctor on a regular basis. Do not
change any aspects of your treatment unless instructed by your doctor.
x Dehydration or l oss of fluids, for example, through sweating, can lead to
incorrect results.
x A very high or very low haematocrit value (proportion of red blood cells)
can lead to incorrect measurements. With a very high haematocrit value
(over 60%), the displayed blood sugar value may be too low. If you have a
very low haematocrit value (below 20%), the blood sugar value may be too
high. If you do not know your haematocrit value, ask your doctor.
x Do not use the test strips to take blood sugar measurements of newborn
infants.
x Metabolites such as uric acid, ascorbic acid, acetaminophen (paracetamol),
dopa, methyldopa, L-dopa, and tolbutamide do not influence the results if
they are present within the physiological value range.
x Lipemia effects: Elevated blood triglyceride levels of up to 22.6 mmol/L
rarely influence the results. Above this level, however, the blood sugar test
may be affected.
Beurer GL34 mmol/L

x Only use fresh capillary whole blood. Do not use serum or plasma.
x Use capillary blood obtained without squeezing the puncture site. When
squeezed, the blood is diluted with lymph from the tissues and therefore
leads to an incorrect measurement result.
x Do not use the test strips at an altitude above 3275 m.
Note
The Beurer GL34 mmol/L measuring system is designed for measuring
capillary whole blood.
Storage and maintenance
WARNING
x Store the measuring device and accessories out of the reach of young
children. Small parts such as the needle lancets, batteries or test strips
may be harmful if swallowed. If parts are swallowed, seek medical advice
immediately.
x The test strip container contains a desiccant that may cause skin or eye
irritations if inhaled or swallowed. Keep the container out of reach of young
children.
Batteries/Saving measured values
WARNING
x Batteries may be fatal if swallowed. Therefore, always store batteries out of
the reach of young children. If a battery is swallowed, seek medical advice
immediately.

carefully and dispose of the lancet.
CAUTION
x Only use the lancing device with needle lancets made by the same manu-
facturer. The use of other needle lancets may impair the function of the
lancing device.
x If the lancing device is manufactured by a third party, consult their instruc-
tions for use.
Choose a site on the body from where you wish to take the blood sample. You
1
can use the lancing device to take a blood sample from the fingertip or alternative sites such as the palm of the hand, forearm, upper arm, thigh, or calf. We
recommend that you take the blood sample from the fingertip. To make the
blood sample as pain-free as possible, do not take the blood directly from the
centre of the fingertip, but instead from slightly to the side of the centre.
WARNING
x If you suspect hypoglycaemia: Always take blood from the
fingertip. This is because changes in blood sugar levels are mo-
re rapidly detected in blood from the fingertip.
x Measurement at the fingertip and measurement at other body
sites (AST) can lead to considerably different measured values.
Always consult your doctor before starting to test at alternative

dried completely before beginning the measurement.
WARNING
x Change the lancing site for every test, e.g. use a different finger or the
other hand. Repeated lancing in the same location may lead to infections,
loss of sensation, or scarring.
x Do not use the AST cap to take a blood sample from the finger.
x Never squeeze the finger to obtain a larger droplet of blood. When squee-
zed, the blood is diluted with lymph from the tissues, which may lead to an
incorrect measurement result.
x Note that inadequate circulation at the puncture site, for example caused
by cold or illness, can lead to inaccurate measurements.
Twist to remove the cap from the lancing device.
Place a sterile needle lancet in the lancing device and
push the lancet firmly into place.
Remove the protective disc from the lancet by twisting
3
while holding the shaft of the lancet firmly. Keep the
protective disc for safe disposal of the used needle
lancet after you have obtained the blood sample.
You will need to use a different cap depending on the
4
site from which you want to take the sample:
Fingertip: Cap (grey)
Other body sites: AST cap (transparent)
Place the selected cap on the lancing device and twist
it into place.
Beurer GL34 mmol/L
16
Five different puncture depths can be selected on the
5
lancing device:
x 1 to 2: Delicate or thin skin
x 3: Normal skin
x 4 to 5: Thick or rough skin
Turn the cap in the appropriate direction until the
arrow points to the required puncture setting.
Pull back the tensioning device until you hear it click
6
into place. If it does not engage, the lancing device
may have unintentionally already been tensioned
when inserting the needle lancet and could already be
engaged.
The lancing device can now be used to take the blood
7
sample. Ensure that the blood remains in a droplet
form and is not smeared.
Blood sample from the fingertip
Place the lancing device firmly against the finger,
slightly to the side of the centre of the fingertip. Press
the release button. Lift the lancing device from the
finger. A round blood droplet of at least
0.5 microlitres (approx. 1.2 mm, original size: z) is required.
Blood sample from an alternative
site (AST)
Choose a site that is soft, not next to a bone, with no
visible veins and without excessive body hair. Warm
the puncture site to ensure good circulation, for example by lightly massaging the area. Place and hold the
lancing device against the puncture site for a few
seconds and press the release button. Continue to
hold the lancing device against your skin until a round
droplet of blood has formed under the cap. Maintain
the pressure until the blood droplet has reached a size
of at least 0.5 microlitres (approx. 1.2 mm, original
size: z). Lift the lancing device carefully away from the skin.
If insufficient blood was collected, increase the punc-
8
ture depth and repeat steps 5 to 7.
Untwist the cap and carefully remove it from the lanc-
9
ing device.

Place the protective disk you kept earlier flat on a hard
10
surface. Pierce the protective disk with the tip of the
needle so that the needle is covered.
Carefully remove the needle lancet from the lancing
11
device and discard the lancet in a suitable sharp-proof
container.
Carefully dispose of all blood samples and materials
with which you have come into contact. This prevents
injury and prevents infection spreading to other people.
Twist the (grey) cap back in place.

dance with the applicable guidelines in order to prevent infection of other
people.
Note
x If the device does not begin the measurement, do not subsequently apply
more blood. Instead, remove the test strip and end the test procedure.
Start again using a new test strip.
x If the test strip is already inserted in the device and you do not apply any
blood to the test strip within three minutes, the device switches itself off. In
this case, remove the test strip and reinsert it into the slit. The device will
switch on again automatically.
x If you experience difficulties applying blood to the test strip correctly, con-
tact customer service.
5.3 Evaluating the measured value
Your blood sugar measuring device can process values between 1.1 and 33.3 mmol/L.
The warning message "Lo" is displayed for measured values below 1.1 mmol/L. The
warning message "Hi" is displayed for measured values above 33.3 mmol/L.
Note
If you suspect that the blood sugar values are incorrect, first repeat the test
and, if necessary, perform a function test using the control solution. If you
consistently have reason to doubt the results, contact your doctor.

5.4 Function test using control solution
The control solution is used for checking the whole blood sugar measuring system. This
enables you to determine whether the measuring device and the test strips are functioning
correctly together and whether the test is performed correctly. It is very important that you
perform these tests using the control solution to ensure accurate measuring results.
CAUTION
Never use control solutions made by other manufacturers. The correct functioning of your Beurer blood sugar measuring device can only be checked
using the Beurer MEDIUM control solution.
When is it recommended to perform a test using the control solution?
x After opening a new test strip container.
x If you suspect that the measuring device or the test strips may be defective.
x If your blood sugar measurement values do not correspond to the way you are feeling..
x If you have dropped the measuri ng device or it has been subjected to other mechani-
cal strain.
x Every time you suspect that the blood sugar results may be incorrect.
It is sufficient to perform a single control solution test if the result is within the recommended range.
WARNING
Do not ingest the control solution. The control solution is only to be used for
function tests and is for external use only.
Note
x Store the control solution in a tightly sealed container at room temperature
below 30°C. Do not refrigerate.
x Store the control solution out of reach of young children.
x Do not store the control solution in the medicine cabinet. It ma y be mis-
taken for medicine to be consumed.
Preparations
x Do not use the control solution once the expiry date has passed. Using control solution
that is out-of-date may lead to incorrect function test results. The expiry date is located
on the bottle next to the egg timer symbol
x The control solution can be kept for three months once the bottle is open. Make a note
of when this time will run out (date of opening + 3 months) on the label

EMC
This device complies with European standard EN 61326 and is subject to specific preventive measures in terms of electromagnetic compatibility. Note that portable and mobile
high-frequency communications equipment may interfere with this device. Further details
can be requested by contacting the customer service address provided below.
Note regarding function of test strips
The test strips enable a quantitative measurement of the glucose content of capillary
whole blood. When the slit for collecting blood comes into contact with a drop of blood, it
fills automatically through simple capillary action. The blood is sucked into the absorbent
slit of the test strip and the measuring device measures the sugar level in the blood.
The test is based on the measurement of an electric current caused by a chemical reaction between the glucose and the test strip reagent. The device analyses this current. The
strength of the current varies according to the glucose content in the blood sample. The
results are shown on the display of the measuring device. Only a small quantity of blood is
required (0.5 microlitres) and the measurement takes approx. 6 seconds. The strips can
detect blood sugar levels in the range 1.1 to 33.3 mmol/L.
Chemical components of the test strip sensor
x Glucose oxidase 10%
x Electron shuttle 50%
x Enzyme protection 8%
x Non-reactive components 32%
Note regarding function of the control solution
The control solution contains a fixed concentration of glucose that reacts with the test
strip. A test with the control solution is performed in the same way as a blood test, but the
control solution is used instead of blood. The results of the control solution test must lie
within the specified results range. This results range is printed on every test strip container.
Chemical composition of the control solution
The control solution is a red-coloured solution with a D-glucose content of less than 0.2%.
Ingredient Percentage concentration
D-glucose 0.05 – 0.19%
Salts 1.4%
Active ingredient for viscosity regulation 15.0%
Standards
The Beurer GL34 mmol/L measuring system fo r self-testing com plies with the following
European Directives and standards: IVD (98/79/EC), EN 61010-1, EN 61010-2-101,

Comparison between measured values and laboratory values
Performance characteristics: Accuracy and precision
The blood sugar results were compared with the YSI 2300 laboratory device. At a concentration of < 4.2 mmol/L, 95% of values were within +/- 0.83 mmol/L, while at a sugar
concentration 4.2 mmol/L,
(coefficient of variation) (%) is < 5 %. The blood sugar measuring device is therefore
comparable with a laboratory system.
> 98% were within 20% of the reference values. The CV
