What instrument is used to measure blood-glucose levels?

The glucose meter is specifically designed for measuring blood glucose levels. This handheld device provides a small blood sample, usually obtained through a fingerstick, and gives an immediate reading of the glucose concentration in the blood. This is vital for individuals managing diabetes or other conditions where blood sugar regulation is essential. Monitoring blood glucose is important for maintaining health and preventing complications associated with high or low glucose levels.

In contrast, a blood pressure monitor tracks blood pressure, measuring the force of blood against the arteries, which is unrelated to blood glucose levels. A cholesterol analyzer focuses on determining cholesterol levels in the blood, another important health measurement, but is not used for blood glucose. Finally, a thermometer measures body temperature and is not applicable for assessing glucose levels at all. Thus, the glucose meter stands out as the appropriate tool for the specific task of measuring blood-glucose levels.
