Glycemia refers to the concentration of sugar or glucose in the blood. In the United States and in many other countries, it is expressed as milligrams per deciliter (mg/dl). In many European countries blood glucose or sugar is also measured as millimoles per decilitre (mmol/dl). These measurements are referred to as the SI units. Blood glucose is one of the most important blood parameters to measure, as abnormal levels can cause severe complications.
