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

• This measuring device must display the blood sugar content in
mg/dL.The unit of measure mg/dL follows the blood sugar value. If
your device does not display mg/dL, contact customer services 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.

• 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.

• The lancing device is intended for self-testing. Never share the lancing
device or needle lancet with another person (risk of infection).

• Use a new sterile needle lancet for each blood sample (for single use only).

Measuring

WARNING

• 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.

• Dehydration or loss of fluids, for example, through sweating, can lead to

incorrect results.

• 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.

• Do not use the test strips to take blood sugar measurements of newborn

infants.

• 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.

• Lipemia effects: Elevated blood triglyceride levels of up to 2000 mg/dL

rarely influence the results. Above this level, however, the blood sugar test
may be affected.

Beurer GL32 mg/dL

6

• Only use fresh capillary whole blood. Do not use serum or plasma.

• 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.

• Do not use the test strips at an altitude above 3275 m.

Note

The Beurer GL32 mg/dL measuring system is designed for measuring
capillary whole blood.

Storage and maintenance

WARNING

• 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.

• 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

• 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.

• Do not throw batteries into a fire: Risk of explosion.

CAUTION

• Remove the batteries if they have run out or if the device is not used for a
long period of time. This prevents any damage that may be caused by
leaking batteries.

• Do not charge the batteries or reactivate them using other means. Do not
disassemble or short-circuit the batteries.

• Do not use rechargeable batteries.

Handling test strips

Note

• Before using the first test strip, ensure that the seal on the container is
unbroken. If the seal is damaged, do not use the test strips.

• Once you have removed the test strip, tightly close the container again
immediately.

• Do not use test strips if the expiry date has passed. The use of expired test
strips can lead to inaccurate measurements. The expiry date is located on
the container next to the egg timer symbol

.

• The test strips can be stored for three months once the container is ope­ned. Make a note of when this time will run out (date of opening + 3
months) on the label

. The shelf life decreases if the expiry date is rea­ched before the end of the 3 months (see the date next to the egg timer
symbol

).

• Do not use the test strips if either of these dates has expired (

/ ).

• Any part of the test strip may be handled with dry, clean hands.

• Use the test strips immediately upon removal from the container.

• Do not bend, cut, or otherwise modify the test strip.

• Do not use test strips that have come into contact with liquids for the blood

sugar measurement.

Storing your test strips

Note

• Store test strips in a cool, dry place between +4°C and 40°C. Protect test
strips against direct sunlight or heat. Do not store test strips in the fridge.

• Test strips may be stored at a relative humidity between 10 % and 85 %.

5 MEASURING YOUR BLOOD SUGAR

WARNING

If you drop the lancing device while a needle lancet is inserted, pick it up
carefully and dispose of the lancet.

CAUTION

• Only use the lancing device with needle lancets made by the same manu­facturer. The use of other needle lancets may impair the function of the
lancing device.

• If the lancing device is manufactured by a third party, consult their instruc­tions for use.

Beurer GL32 mg/dL

5.1 Obtaining a blood sample

Preparing to take the blood sample

1

Choose a site on the body from where you wish to take the blood sample. You
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

• 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.

• 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
sites.

2

Have the following components ready: Measuring device, container of test strips,
lancing device, and a sterile needle lancet. If obtaining a blood sample from a
site other than the fingertip, you will also need the AST cap.

3

Before taking the sample, wash your hands using soap and warm water. In addi­tion to optimal hygienic conditions, this is also ensures good circulation of blood
through the fingertips. Dry your hands carefully. Also ensure that your lancing site
is hygienically clean if taking a blood sample from an alternative site (AST).

WARNING
If you wipe the lancing site with alcohol, ensure that the site has

dried completely before beginning the measurement.

Taking the blood sample

WARNING

• 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.

• Do not use the AST cap to take a blood sample from the finger.

• 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.

• Note that inadequate circulation at the puncture site, for example caused
by cold or illness, can lead to inaccurate measurements.

Beurer GL32 mg/dL

16

1

Twist to remove the cap from the lancing device.

2

Place a sterile needle lancet in the lancing device and
push the lancet firmly into place.

3

Remove the protective disc from the lancet by twisting
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.

4

You will need to use a different cap depending on the
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.

5

Five different puncture depths can be selected on the
lancing device:

• 1 to 2: Delicate or thin skin

• 3: Normal skin

• 4 to 5: Thick or rough skin

Turn the cap in the appropriate direction until the
arrow points to the required puncture setting.

6

Pull back the tensioning device until you hear it click
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.

Beurer GL32 mg/dL

17

7

The lancing device can now be used to take the blood
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.

8

If insufficient blood was collected, increase the punc­ture depth and repeat steps 5 to 7.

9

Untwist the cap and carefully remove it from the lanc­ing device.

10

Place the protective disk you kept earlier flat on a hard
surface. Pierce the protective disk with the tip of the
needle so that the needle is covered.

Beurer GL32 mg/dL

18

11

Carefully remove the needle lancet from the lancing
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.

12

Twist the (grey) cap back in place.

5.2 Measuring the blood sugar value

1

Hold the measuring device so that the display is facing you.

2

Insert a test strip, contacts first, into the device. Ensure that the front side is
facing you. You can handle any part of the test strip with clean, dry hands.

3

The device switches on automatically and shows the start display, shortly
followed by the checking symbol “

“ . As soon as the flashing blood droplet

symbol 6 is displayed, the device is ready to perform measurements.
Hold the blood collection slit (at the point of the test

strip) against the blood droplet. Do not press the
puncture site (fingertip or other body part) against the
test strip. The blood must not be smeared. The blood
is sucked into the slit.

4

WARNING

Hold the blood collection slit of the test strip against the blood
droplet until the slit is completely filled and you hear a beep.
Withdrawing the test strip from the blood droplet before the beep
may lead to incorrect measurements.

5

Once the slit is filled with blood, the device performs the blood sugar meas­urement. The measuring device counts down for 6 seconds, and the result of
the measurement is then shown in the display. Read the measured value. For
an explanation of the measured value and possible actions, see the next
chapter "5.3 Evaluating the measured value", page 19.
If an error message is displayed, refer to chapter “8 Troubleshooting" on page 29.

Beurer GL32 mg/dL

19

6

Remove the test strip from the device and dispose of it carefully in accor­dance with the applicable guidelines in order to prevent infection of other
people.

Note

• 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.

• 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.

• If you experience difficulties applying blood to the test strip correctly, con­tact customer service.

5.3 Evaluating the measured value

Your blood sugar measuring device can process values between 20 and 600 mg/dL. The
warning message "Lo" is displayed for measured values below 20 mg/dL. The warning
message "Hi" is displayed for measured values above 600 mg/dL.

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.

The following table shows a classification of blood sugar values according to the guide­lines of the German Diabetes Association (DDG).

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?

• After opening a new test strip container.

• If you suspect that the measuring device or the test strips may be defective.

• If your blood sugar measurement values do not correspond to the way you are feeling..

• If you have dropped the measuring device or it has been subjected to other mechani-

cal strain.

• 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

• Store the control solution in a tightly sealed container at room temperature
below 30°C. Do not refrigerate.

• Store the control solution out of reach of young children.

• Do not store the control solution in the medicine cabinet. It may be mis-

taken for medicine to be consumed.

Preparations

• 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

.

• 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

. The shelf life
decreases if the expiry date is reached before the end of the 3 months (see the date
next to the egg timer symbol

).

Beurer GL32 mg/dL

22

• Do not use the control solution if either of these dates has expired (

/ ).

• Allow the measuring device, test strips and control solution to reach room temperature
(+20°C to +25°C).

Performing a function test using the control solution

1

Hold the measuring device so that the display is facing you.

2

Insert a test strip into the slit on the measuring device, contacts first. Ensure
that the front side of the test strip is facing towards you (see "3.3 Test strip",
page 11).

3

The device switches on automatically and shows the start display, shortly
followed by the checking symbol “

“. As soon as the flashing blood droplet

symbol 6 is displayed, the device is ready to perform measurements.

4

Press the ON/OFF/Forwards button to switch to control mode. In control
mode, the measured value is not stored and hence does not distort your
measurement statistics.

5

"CTL" appears in the display.

6

Shake the control solution well before use. Unscrew the cap and squeeze out
a drop of solution. Wipe away the first drop and squeeze out an additional
drop.

7

To prevent the remaining control solution in the bottle from becoming con­taminated through the tip of the bottle in contact with the test strip, do not
apply the drop directly to the test strip. Instead, apply the drop to a clean
surface, and then apply the drop from there to the blood collection slit on the
test strip. The solution is sucked into the slit. Wipe the tip of the bottle using a
clean, dry paper tissue.

8

Once the slit is filled with solution, the device begins the measurement. The
device counts down for 6 seconds, and the result of the measurement is then
shown in the display.

9

Check whether the result is within the specified results range for the control
solution. This results range is printed on the test strip container.

Beurer GL32 mg/dL

23

Expected results

At room temperature, the measurement results for 95% of all control solution tests should
lie within the results range printed on the test strip container.

WARNING
The results range printed on the test strip container applies only for the control

solution. This is not a recommended value for your blood sugar level.

If measurement results are outside the specified range, check the following possible
causes:

Cause Remedy

• The drop of control solution was not
discarded.

• The tip of the bottle was not wiped
clean.

• The bottle was not shaken vigourously
enough.

6 THE MEASURED VALUE MEMORY

Your blood sugar value is stored automatically each time you take a measurement. Ex­ception: if "CTL" is activated during a measurement with control solution, the value is not
stored. The measured value memory can store up to a maximum of 448 values. Once this
number is reached, the measured value always replaces the oldest value in the memory.
You can display the average value for the last 7, 14, 21, 28, 60 and 90 days, as well as
displaying each value individually.

Note

• If measured values are already stored in the memory and you then reset
the date, the average values are calculated according to the new time pe­riod.

• "---" indicates that the measured value memory is empty. "OFF" is then
displayed briefly and the measuring device switches off automatically.

6.1 Displaying individual values

You can display individual values for the last 448 measurements. The most recent value

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 in 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 20 to 600 mg/dL.

Chemical components of the test strip sensor

• Glucose oxidase 10%

• Electron shuttle 50%

• Enzyme protection 8%

• 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 GL32 mg/dL measuring system for self-testing complies with the following
European Directives and standards: IVD (98/79/EC), EN 61010-1, EN 61010-2-101,
EN 13640, EN ISO 15197, MDD (93/42/EC).

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 < 75 mg/dL, ≥ 95% of values were within +/- 15 mg/dL, while at a sugar concen­tration ≥ 75 mg/dL,

> 98% were within 20% of the reference values. The CV (coefficient of

variation) (%) is < 5 %. The blood sugar measuring device is therefore comparable with a
laboratory system.
