The blood glucose watch is a portable device that is usually easy to use by simply wearing the watch on your wrist for blood glucose monitoring anytime, anywhere.
But blood glucose watches are not as accurate or precise as traditional blood glucose instruments, and can only provide approximate blood glucose values, so it is recommended to use a professional blood glucose instrument to take measurements when conducting blood glucose monitoring.
Also, blood glucose watches should only be used as an aid in diabetes management and should not be relied upon solely for treatment decisions.
