warninGs and safety notes
Risk of infection
All components of the blood glucose monitor and its accessories may come into contact
with human blood and are therefore a possible source of infections.
Warning
• This blood glucose monitor must display the blood glucose content in mg/dL. The unit of measure-
ment mg/dL accompanies each blood glucose value. Please contact Customer Services if the device
does not display mg/dL. You risk damaging your health if you measure your blood glucose value
using a unit of measurement with which you are not familiar, misinterpret the values and therefore
take incorrect measures.
• When using the blood glucose monitor for various persons, observe the generally applicable regula-
tions regarding disinfection, safety and contamination.
• Medical carers and others who use this system on several patients must be aware that all products
or objects that come into contact with human blood must be handled, even after cleaning, as though
they could transfer pathogens.
• The lancing device is suitable for self-testing. Do not share the lancing device or lancet needles with
others or amongst various patients (risk of infection!).
• Use a new, sterile lancet needle for each blood sample (for single use only).

General notes
Warning
Do not use the device in the vicinity of strong electromagnetic fields and keep it away from radio
systems or mobile telephones.
Measuring the blood glucose content
Warning
• The measurements taken by you are for your information only – they are no substitute for a medical
examination! Consult your GP regularly regarding your measured values. Do not alter the procedures
prescribed by your GP.
• Despite the simple usage of the Beurer GL42 monitor for self-monitoring of blood glucose levels, you
may possibly need to obtain instructions for using the system from your healthcare professional (for
example, your GP, chemist or diabetes consultant). Only proper use will guarantee exact measure-
ments.
• A lack of water, high fluid loss, for example perspiration, frequent passing of water, severe hypoten-
sion (low blood pressure), shock or hyperosmolar hyperglycaemic non-ketotic coma may lead to
incorrect measured results.
• An excessively high or low hematocrit value (proportion of red blood cells) may lead to incorrect
measurements. In the event of a very high hematocrit value (above 60%), the displayed blood glu-
cose value may be too low; in the event of a very low hematocrit value (below 20%), it may be too
high. Consult your GP if you do not know your hematocrit 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.
•The level of Acetaminophen (up to 10 mg/dL), Ascorbic acid (up to 4 mg/dL), Bilirubin (up to
20 mg/dL), Cholesterol (up to 500 mg/dL), Creatinine (up to 10 mg/dL), Dopamine (up to 5 mg/dL),
EDTA (up to 400 mg/dL), Fructose (up to 200 mg/dL), Galactose (up to 200 mg/dL), Gentistic acid
(up to 2 mg/dL), Glutathione (up to 3 mg/dL), Haemoglobin (up to 200 mg/dL), Heparin (up to
60 mg/dL), Ibuprofen (up to 40 mg/dL), Icodextrin (up to 200 mg/dL), Lactose (up to 200 mg/dL), L‐
DOPA (up to 3.0 mg/dL), Maltose (up to 200 mg/dL), Methyl‐DOPA (up to 1.25 mg/dL), Pralidoxime
Iodide (up to 1.25 mg/dL), salicylate (up to 20 mg/dL), Tetracycline (up to 4 mg/dL), Tolazamide
(up to 55ug/dL), Tolbutamide (up to 100 mg/dL), Triglyceride (up to 3000 mg/dL), Uric acid (up to
7mg/dL), and Xylose (up to 5 mg/dL) in blood has no significant interference reaction (the average
dierence between the test sample and the control sample ≤ 0.55 mmol/L (10 mg/dL) at glucose
concentration of 50~100 mg/dL and ≤ 10% at glucose concentration of 250‐300 mg/dL) on GL42.
•The xylose level (up to 10 mg/dL) in the blood causes a significant deviation with the GL42 device
(average deviation between test and control test >0.55 mmol/L (10 mg/dL) with a blood glucose
concentration of 50-100 mg/dL and >10% with a blood glucose concentration of 250-300 mg/dL).
• Use fresh capillary whole blood only. Do not use serum or plasma.
• Use capillary blood without squeezing the penetration area. If the area is squeezed, the blood is di-
luted with tissue fluid and this may lead to an incorrect result.
• Do not use the test strips above an altitude of 6,000 m.

functional check usinG control solution
The control solution is used to test the entire blood glucose monitoring system. This helps to deter-
mine 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 blood
glucose monitor if it has been dropped or is damaged. The control solution is available separately.
Please observe the additional notes in the instructions for using the control solution for the test.

18 Beurer GL42 mg/dL
Important
• Do not use third-party control solution. Correct functioning of the measuring device can only be
tested using the Beurer control solutions (LEVEL5 + LEVEL6).
• 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 moni-
tor.
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 be-
tween 20 °C and 26 °C.
1
Hold the blood glucose monitor so that the display is facing you.
2
Insert a test strip into the slot on the blood glucose monitor with the contacts first. Make sure
that the front of the test strip is facing you (see “Test strips” on page 12).
3
The device automatically switches on and briefly shows the initial display. The device is ready
for measurement as soon as the hand and the symbol flash.
IMPORTANT: Control solutions and blood react to temperature influences in dierent 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.
Note
Press the rocker switch “+” or “–” [2] to change to the control mode. “ ” is shown on the
display. This means that the result value is not stored in the memory, therefore not influencing
your measured value statistics. Press “+” or “–” [2] again. “ ” disappears from the display
and the value is stored normally in the memory.
4
A clean surface is required to correctly perform a functional test.
Shake the control solution well before use.
Undo the cap and press two drops next to each other on the
clean surface without touching them. Use the second drop for
the measurement.
Note
Do not apply the drop directly to the test strip to avoid contaminating the remaining control
solution in the bottle by touching the test strip with the tip of the bottle.

Beurer GL42 mg/dL 19
5
Hold the input gap (at the tip of the test strip) to the drops of control solution until the gap is
completely filled and the measuring device in the display starts counting backwards.
When the gap is suciently filled with solution, the device performs a measurement. The de-
vice counts down for approx. five seconds. The measured result is then shown on the display.
6
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.
Expected results
At room temperature, the measurements of 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 rec-
ommended value for your blood glucose level.
If measured values are outside the specified range, check the following possible causes:
Cause Action
• The first drop of control solution was not dis-
posed 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 and/or test strips have passed
their expiry date or are contaminated.
Repeat the test using a new bottle of control
solution and/or new test strip.
The control solution, test strips or blood glucose
monitor are too warm or too cold.
Bring the control solution, test strips and blood
glucose monitor to room temperature (+20°C to
+26 °C) and repeat the test.
The test strips and control solution were kept at
a temperature and humidity outside the speci-
fied range.
Repeat the test using new/correctly stored test
strips and control solution.
Damaged test strips.
For example
• Test strips that 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.
Old test strips. Open a new box of test strips. Repeat the test.
There is a problem with the blood glucose moni-
tor.
Contact Customer Services.
Functional test was incorrectly performed. Repeat the test and follow the instructions.

20 Beurer GL42 mg/dL
Warning
Do not use the system to measure your blood glucose level if you are repeatedly provided with
measurements outside the specified range when using control solution. Contact Customer Services.
