amount of blood is required (0.6 microlitres) and measurement duration is approx. five seconds. The
test strip detects blood glucose values from 20 to 630 mg/dL.
Chemical components of the test strip sensor
• FAD glucose dehydrogenase 6 %
• Potassium ferricyanide 56 %
• Non-reactive components 38 %
Control solution functionality
The control solution contains a fixed amount of glucose that reacts with the test strip. A test with con-
trol solution is similar to a blood test. However, control solution is used instead of blood. The measured
result using control solution must be within the result range. This range is printed on each test strip box.
Chemical composition of the control solution
The control solution is a red solution with the following D-glucose level (in percentage shares):
Ingredients Control solution LEVEL 3 Control solution LEVEL 4
D-glucose 0.14 % 0.37 %
Non-reactive components 99.86 % 99.63 %
Standards
The Beurer GL44 monitor corresponds to European guidelines IVD (98/79/EC) and MDD (93/42/EC).
Comparison of measured values with laboratory values
Performance characteristics: accuracy and precision
Whole blood glucose test results were compared to the YSI 2300 laboratory device. At a concen-
tration of < 75 mg/dL, ≥ 98 % were at +/-15 mg/dL, while at a glucose concentration of ≥ 75 mg/dL,
≥ 98 % were within 20 % of the reference values. The CV (coecient of variation) is < 5 %. The blood
glucose monitor is therefore comparable to a laboratory system.

in generally relevant specialist medical literature.
