Getting to know your device
The GL50 evo 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 easy operation via a single scroll wheel 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 language) and use
the results to monitor your blood glucose values.
Alternatively, you can transfer the measured values to your smartphone/tablet using the optional
Bluetooth®cap.

2 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
• Blood glucose values are displayed in mg/dL or mmol/L. 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. Therefore, please
ensure that this monitor displays a unit of measurement with which you are familiar. The unit
of measurement accompanies each blood glucose value. Please contact Customer Services
if the device displays the incorrect unit of measurement.
• When using the blood glucose monitor for various persons, observe the generally applicable
regulations 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. Never independently alter
the procedures prescribed by your GP.
• The Beurer GL50 evo monitor provides a simple way of monitoring your own blood glucose values,
however, 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
exact measurements.
• This device may be used by people with reduced mental capabilities provided that they are supervised
or have been instructed on how to use the device safely and are fully aware of the consequent risks
of use.
• A lack of water, high fluid loss, for example perspiration, frequent passing of water, severe hypotension
(low blood pressure), shock or hyperosmolar hyperglycaemic non-ketotic coma may lead to incorrect
measurements.

Beurer GL50 evo 9
• 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.
• Use capillary blood without squeezing the penetration area. Squeezing the area causes the blood to
be diluted with tissue fluid and this may lead to an incorrect measurement.
• Do not use the test strips above an altitude of 7010 metres.
• Very high levels of humidity may influence the test results. Relative humidity of more than 90% may
lead to inaccurate results.
Note
The Beurer GL50 evo measuring system is intended for measuring capillary and venous 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, cover caps 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 monitor is made from precision and electronic components. The accuracy of the measured values
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.
Repairs
Note
• Do not open the device. Failure to comply with this instruction will void the warranty.
• Do not repair the device yourself. 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
disposing 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.
