Blood Glucose Test Meter should be used together with a test strip for in vitro quantitative detection of glucose concentration in human whole blood, suitable for clinical routine medical testing as well as self-monitoring of blood glucose for diabetes patients. 
The testing range of the meter is from 1.1mmol/L 0r20mg/dL to 600mg/dL. The symbol of Hi or Lo represents the result beyond the testing range. The blood glucose test meter can store at least 250 test results with corresponding date and time.
