Blood sugar monitoring in diabetes. Close-up of a 16-year-old female diabetic patient using a traditional finger prick device (lancet) to draw a blood sample to measure her blood glucose levels. The sample is placed on a paper strip that is inserted into a meter (not shown). The meter then measures and displays the level of glucose in the blood sample. This allows the patient to accurately tailor their insulin dose.
