glükoosimetrid

Glükoosimeeter, commonly referred to as a glucose meter, is a portable electronic device used to measure the concentration of glucose in the blood. This measurement, known as blood glucose level or blood sugar level, is crucial for individuals managing diabetes mellitus. By monitoring their glucose levels, people can make informed decisions about their diet, exercise, and medication to maintain blood glucose within a target range, thereby preventing or delaying long-term complications of diabetes.

The principle behind most glucose meters involves a small blood sample, typically obtained through a finger prick using a lancet. This blood droplet is then applied to a disposable test strip, which contains enzymes that react with glucose. This reaction produces an electrical signal or a color change, depending on the specific meter technology. The glucose meter then interprets this signal and displays the blood glucose concentration, usually in milligrams per deciliter (mg/dL) or millimoles per liter (mmol/L).

Modern glucose meters are designed for ease of use, accuracy, and speed, with results often available in a matter of seconds. Some devices offer additional features such as memory storage for past readings, averaging capabilities, and connectivity to smartphones or computers for data analysis and sharing with healthcare providers. Accurate calibration and proper usage of test strips are essential for reliable results. Regular calibration, using control solutions, and ensuring the test strips are stored correctly away from moisture and extreme temperatures are important maintenance practices.
