As an indispensable instrument for diabetes monitoring, the rapid blood glucose meter has been popularized among diabetic patients in our city. Adjusting the treatment plan based on blood glucose monitoring is an effective measure to achieve treatment goals and prevent chronic complications such as cardiovascular, cerebral, renal, and nervous system diseases.
