A<unk>  (or<unk> ter) is a medical device for determining the approximate concentration of<unk>  in the blood.  It is a key element of home blood<unk>  monitoring (HBGM) by people with diabetes mellitus or with proneness to hypoglycemia. A small drop of blood obtained by pricking the skin with a lancet is placed on a disposable test strip, which the meter reads and uses to calculate the blood<unk>  level.  The meter then displays the level in mg/dl or mmol/l.
Since approximately 1980, a primary goal of the management of type 1 diabetes has been the achievement of closer-to-normal levels of<unk>  in the blood for as much of the time as possible, guided by HBGM several times a day.  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.
