Page 15: Taking The Blood Glucose Measurement
• Do not squeeze your finger to obtain a larger drop of blood. If squeezed, the blood is diluted with tis- sue fluid and this may lead to an incorrect measurement. • Please note that insufficient blood circulation at the puncture area, e.g. caused by cold temperatures or illness, may lead to incorrect results. Beurer GL48/GL49... - Page 16 The blood is sucked into the gap. Note Error message “002” appears on the display if the gap was not correctly and sufficiently filled with blood.

Page 32: Comparison Of Measured Values With Laboratory Values
Precision Three lots of the GL48/GL49 blood glucose test strips have been tested to assess the precision of the GL48/GL49 blood glucose measuring system. This includes a repeat assessment using venous blood and a laboratory precision assessment using the control material. The blood glucose content of the ve-nous blood samples ranges from 45.0 to 365.0 mg/dL (2.5 to 20.3 mmol/... - Page 33 The GL48/GL49 blood glucose monitor compared to the Cobas hexokinase method. Three lots of GL48/GL49 blood glucose test strips have been tested to assess the system accuracy of the GL48/ GL49 blood glucose measuring system and to compare it with the reference method in which capillary whole blood concentrations of 36.3 mg/dL (2.0 mmol/L) to 597.0 mg/dL (33.1 mmol/L) have been used.
