Indications for Use

The BaseSens I Blood Glucose Monitoring System is used for the quantitative measurement of glucose levels in capillary whole blood as an aid in monitoring the effectiveness of diabetes management at home or in clinical settings. The BaseSens I Blood Glucose Monitoring System should be used only for testing outside the body (in vitro diagnostic use only). The BaseSens I Blood Glucose Monitoring System is not intended for the diagnosis of or screening for diabetes mellitus, and is not intended for use on neonates. Testing sites include the fingertip along with alternate sites testing (AST) on the forearm, palm, thigh and calf. AST in this system can be used only during steady-state blood glucose conditions. BaseSens I Test Strip is used with the BaseSens I Blood Glucose Meter for quantitatively measuring glucose in capillary whole blood. The BaseSens I Test Strip is intended for self-testing outside the body (in vitro diagnostic use only). The BaseSens I Test Strips are not intended for the diagnosis of or screening for diabetes mellitus, and are not intended for use on neonates. Testing sites include the fingertip along with alternate sites testing (AST) on the forearm, palm, thigh and calf. AST in this system can be used only during steady-state blood glucose conditions. BaseSens I Control A&B Solutions are red liquid to check that both the meters and test strips are working together properly. It contains a known range of glucose as written on the bottle.

L. Test Principle:
The BaseSens I Blood Glucose Monitoring System uses electrochemical methodologies. The system quantitatively measures blood glucose levels using an amperometric method, which involves detecting the current produced from glucose oxidation. The electrons generated during this reaction are transferred from the blood to the electrodes. The magnitude of the resultant current is proportional to the concentration of glucose in the specimen and the signal is converted into a readout displayed on the meter.
