Beurer GL50
• A haematocrit value (proportion of red blood cells) between 30% and 55% 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 55%), the displayed blood
glucose value may be too low; in the event of a very low haematocrit value (below 30%), 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 of 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 capillary 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 at altitudes above 7,010 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 measuring system is intended for measuring capillary and venous whole blood.
