Dynamic blood glucose meters are generally able to accurately reflect the blood glucose concentration. Dynamic blood glucose meter is through the blood glucose sensing chip placed in the body, every period of time can automatically record the blood glucose value as well as accurately draw out the daily blood glucose change curve, to play a dynamic, continuous monitoring of blood glucose changes, so the dynamic blood glucose meter is generally able to accurately respond to the blood glucose concentration. However, not everyone is recommended to use dynamic glucose meter for blood glucose monitoring. It is generally recommended that patients with poor blood glucose control and suspected “dawn phenomenon” use dynamic glucose meter for testing. Patients who need to use ambulatory glucose meters for blood glucose monitoring should do so under the guidance of a doctor.
