![]() This biosensor was based on a thin layer of glucose oxidase (GOx) on an oxygen electrode. In 1962, Clark and Ann Lyons from the Cincinnati Children's Hospital developed the first glucose enzyme electrode. Leland Clark presented his first paper about the oxygen electrode, later named the Clark electrode, on 15 April 1956, at a meeting of the American Society for Artificial Organs during the annual meetings of the Federated Societies for Experimental Biology. The benefits include a reduction in the occurrence rate and severity of long-term complications from hyperglycemia as well as a reduction in the short-term, potentially life-threatening complications of hypoglycemia. Since approximately 1980, a primary goal of the management of type 1 diabetes and type 2 diabetes mellitus has been achieving closer-to-normal levels of glucose in the blood for as much of the time as possible, guided by HBGM several times a day. The meter then displays the level in units of mg/dL or mmol/L. A small drop of blood, obtained from slightly piercing a fingertip with a lancet, is placed on a disposable test strip that the meter reads and uses to calculate the blood glucose level. It is a key element of glucose testing, including home blood glucose monitoring (HBGM) performed by people with diabetes mellitus or hypoglycemia. ![]() It can also be a strip of glucose paper dipped into a substance and measured to the glucose chart. Measure concentration of glucose in the bloodĪ glucose meter, also referred to as a " glucometer", is a medical device for determining the approximate concentration of glucose in the blood. Test times vary from 5 seconds to 2 minutes (modern meters typically provide results in 5 seconds). Four generations of blood glucose meter, c. ![]()
