The TD-4140 Smart Dongle Blood Glucose plus β-ketone Monitoring System consists of the Smart Dongle meter, Smart Dongle blood glucose test strips, Smart Dongle β-ketone test strips, and the Procheck mobile application as the display component of the system. This system is intended to be used for the quantitative measurement of glucose (sugar) and β-ketone in fresh capillary whole blood from the finger.

This 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 intended to be used by a single person and should not be shared. This system should not be used for the diagnosis of or screening for diabetes, nor for use on neonates.
