What is a blood sugar meter?

A blood sugar meter, also called a blood glucose meter, measures the level of glucose in the blood. According to Mayo Clinic, blood glucose meters help diabetics manage their condition by tracking fluctuations in glucose.

Blood glucose meters are found in a variety of styles to cater to specific groups, according to Mayo Clinic. This includes talking meters for the hearing-impaired, large screens for the visually impaired and backlighting for reading at night. Meters also keep different types of information. For example, some simply display the reading, while other meters keep track of the time, date, reading and glucose level trends and allow users to download the information to a computer.
