Storage for HemoCue® Glucose 201+ Analyzer: The analyzer can be stored at temperature 0-50 °C (32-122 °F).
Storage for microcuvettes
kept in a vial
Store unopened HemoCue® Glucose 201 Microcuvettes below 8 °C (46 °F) (incl. storage in a freezer). Note, microcuvettes stored in a freezer must be allowed to reach room temperature (approx. 30 minutes) before analysis. Microuvettes kept in an opened vial are stable for
30 days when stored in a refrigerator at
2–8 °C (35 – 46 °F).
After breaking the seal, the vial can be stored at room temperature for up to
3 days.
Close the lid immediately after cuvettes are removed from the vial.
Storage for individually packaged microcuvettes
Store unopened HemoCue® Glucose 201 Microcuvettes below 8 °C (46 °F) (incl. storage in a freezer). Note, microcuvettes stored in a freezer must be allowed to reach room temperature (approx. 30 minutes) before analysis. The individually packaged microcuvettes can be stored at room temperature for up to 3 days.
Method: (1) Banauch, et. al., Z Klin Chem u Klin Biochem, 1975, 13, 101-107.

Principle: Saponin hemolyzes the erythrocytes and their contents are released. α-D-glucose is transformed to ß-D-glucose using the mutarotase enzyme. The GDH enzyme (glucose dehydrogenase), specific for ß-D-Glucose, acts as a catalyst in the oxidation of ß-D-Glucose in the presence of NAD (nicotinamide adenine dinucleotide) to form NADH. The GDH/mutarotase enzyme system ensures a molar relationship between the available glucose and the NADH produced. In the presence of NADH, using diaphorase as a catalyst, the MTT chromogene (a tetrazolium salt) is formed to a colored formazan. The colored formazan is quantified photometrically with a two-wavelength method (660 and 840 nm).
Sample material: Capillary, venous or arterial whole blood.
Measurement range: Whole blood values: 0-27.8 mmol/L (0-500 mg/dL). Plasma equivalent values: 0-31 mmol/L (0-560 mg/dL).
Results: In about 40-240 seconds, depending on blood glucose concentration.
Sample volume: <4 µL.
Weight: 350 g (0.77 pounds) with batteries installed.
Power: AC Adapter or batteries.
Operating temperature: 15-27 °C (59-80 °F).
Interface: Printer and PC.
Quality control: Built-in "selftest". The system can be verified using liquid controls.
Calibration: Calibration is traceable to the ID GC-MS method.The analyzer is factory calibrated and needs no further calibration.
Storage for HemoCue® Glucose 201 RT Analyzer: The analyzer can be stored at temperature 0-50 °C (32-122 °F).
Storage for individual packaged HemoCue® Glucose 201 RT Microcuvettes: The microcuvettes are to be stored at 0–30 °C (32–86 °F).
Unused HemoCue® Glucose 201 RT Microcuvettes should be kept in the original package but once an individual package is opened, the microcuvette must be used immediately or discarded. Use the microcuvettes prior to the expiration date that is printed on the package.
Method: HemoCue® Glucose 201 RT system is a Modified glucose dehydrogenase methode, where the total amount of glucose is measured photometrically.
Principle: The chemical reaction in the cavity has two phases, hemolysis and the glucose reaction. The glucose reaction is a modified glucose dehydrogenase method in which a tetrazolium salt (MTT) is used to obtain a quantification of glucose in visible light. α-D-glucose is transformed to β-D-glucose using mutarotase. Glucose dehydrogenase acts as a catalyst for the oxidation of β-D-glucose, to form NADH, which in the presence of diaphorase produces a colored formazan with MTT.
