Blood sugar monitoring in diabetes. Close-up of a 16-year-old female diabetic patient using a traditional meter to measure her blood glucose levels. A drop of the patient's blood is placed on a paper strip that is inserted into the meter. The meter then measures and displays the level of glucose in the blood sample. This allows the patient to accurately tailor their insulin dose.
