With kind regards,
Your Beurer team.
Getting to know your instrument
The GL50 blood glucose monitor is intended for fast and simple blood glucose measurement of fresh
capillary blood samples, either for self-testing or in a clinical environment by trained personnel.
It enables you to measure your blood glucose quickly and easily, store the measured values and display the average of all measured values, thereby providing optimum assistance for monitoring your
diabetes. The test is performed exclusively externally (IVD).
The backlit display shows measured values clearly. The user-friendly design with handy test strips
and the simple controls with just a small number of buttons guarantee simple, yet reliable measurements.
The device can be connected directly to a PC using the integrated USB connection. You can evaluate
the measured values on your PC using special software (in English and German) and use the results
to monitor your blood glucose values.

Note on important information
Beurer GL50 mg/dL 7

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 meas-
urement 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.
•
The Beurer GL50 monitor provides a simple way of monitoring your own blood glucose levels, how-
ever, you may need to obtain information on how to use the system from your healthcare professional (for example, your GP, chemist or diabetes consultant). Only proper use will guarantee precise
measurements.
•
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 (HHNKC) may
lead to incorrect measured results.
8 Beurer GL50 mg/dL
•
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 55%), the displayed blood glucose value may be too low; in the event of a very low hematocrit value (below 30%), 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.
•
Lipemia eects: High blood triglyceride values of up to 1000 mg/dL have minimum influence on the
results. However, triglyceride values above this level may aect the blood glucose test.
•
High blood cholesterol values of up to 500 mg/dL have minimum influence on the results. However,
cholesterol values above this level may aect the blood glucose test.
•
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 7010 m.
•
Very high levels of humidity may influence the test results. Relative humidity of more than 90% may
lead to inexact results.
Note
T
he Beurer GL50 mg/dL measuring system is intended for measuring capillary whole blood.
Storage and maintenance
Warning
•
Store the blood glucose monitor and its accessories out of reach of small children and pets. Small
parts, such as lancet needles, batteries or test strips may be life-threatening when swallowed. If
swallowed, seek medical attention immediately.
•
The test strip box contains desiccant, which may irritate the skin or eyes when inhaled or swallowed.
Keep the box out of the reach of children.
The blood glucose monitor is made from precision and electronic components. The accuracy of the
measurements and service life of the device depend on its careful handling:
•
Protect the device and its accessories from impacts, humidity, dirt, marked temperature fluctuations
and direct sunlight. Do not store the device, test strips and control solution in your vehicle, in the
bathroom or in a cooling appliance.
•
Do not drop the device.

remove the batteries from the battery compartment.
Attention!
•
Leaking or damaged batteries may burn the skin therefore use suitable protective gloves if this is
the case.
Note
•
The stored blood glucose values are retained when the batteries are replaced. If applicable, the date
and time must be reset after replacing the batteries.
•
Use lithium-ion batteries only.
Repairs
Note
•
Do not open the device. Failure to comply will result in voiding of the warranty.
•
Do not repair the device. Proper operation can no longer be guaranteed in this case.
•
Please contact Customer Services for repairs.
Disposal
Warning
• It is essential to comply with the generally applicable safety precautions for handling blood when dis-
posing of materials from the blood glucose monitor. Dispose of all blood samples and materials with
which you or your patients come into contact correctly in order to prevent injury and infection of other
persons.
•
After use, dispose of test strips and lancets in a puncture-proof container.
Note
Batteries must not be disposed of with household waste. As a consumer, you are required by law to
recycle used batteries. You can recycle your old batteries at public collection points in your community
