Beurer GL50 mg/dL 9
• 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 glu-
cose 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 effects: High blood triglyceride values of up to 1000 mg/dL have minimum influence on the
results. However, triglyceride values above this level may affect 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 affect 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
The 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.
