## Indications for use
The CareSens N Voice Blood Glucose Monitoring System is intended for the quantitative measurement of glucose in fresh capillary whole blood samples drawn from the fingertips and alternative sites such as the forearm, palm, thigh, and calf. Alternative site testing should be used only during steady-state blood glucose conditions. The CareSens N Voice Blood Glucose Monitoring System is intended for self testing outside the body (in vitro) by people with diabetes at home as an aid to monitor the effectiveness of diabetes control. The system is intended to be used by a single person and should not be shared. It is not intended for use on neonates and is not for the diagnosis or screening of diabetes. The CareSens N Single Blood Glucose Test Strips are for use with the CareSens N Voice Blood Glucose Meter to quantitatively measure glucose in fresh capillary whole blood samples drawn from the fingertips and alternative sites. The CareSens Control Solutions are for use with the CareSens N Voice Meter and CareSens N Single Test Strips to check that the meter and the test strips are working together properly and that the test is performing correctly.
