The TD-4268 Blood Glucose Monitoring System is intended for use in the quantitative measurement of glucose in fresh capillary whole blood samples from the finger. It is intended to be used by a single person and should not be shared.
The TD-4268 Blood Glucose Monitoring System is intended for self testing outside the body (in vitro diagnostic use) by people with diabetes at home as an aid to monitor the effectiveness of diabetes control. It is not intended for the diagnosis of or screening for diabetes mellitus or be used on neonates.
The TD-4268 Blood Glucose Test Strips are for use with the TD-4268 Blood Glucose Meter to quantitatively measure glucose (sugar) in fresh capillary whole blood samples.
The TD-4268 Multi Blood Glucose Monitoring System is intended for use in the quantitative measurement of glucose in fresh capillary, venous and neonatal whole blood samples. The TD-4268 Multi Blood Glucose Monitoring System is intended for testing outside the body (in vitro diagnostic use) and is intended for multiple patient use in professional healthcare settings as an aid in monitoring the effectiveness of diabetes control. It is not intended for the diagnosis of or screening for diabetes mellitus.
Professionals may test with capillary, venous and neonatal whole blood. Capillary samples may be drawn from the fingertip, and in the case of neonates, from the heel.
The system is only used with single-use, auto-disabling lancing devices.
The TD-4268 Multi Blood Glucose Test Strips are for use with the TD-4268 Multi Blood Glucose Meter to quantitatively measure glucose (sugar) in fresh capillary, venous and neonatal whole blood samples.
Indications for use as stated in the FDA summary.
