Blood and its components cannot be manufactured or harvested. People who need blood or plasma transfusions must rely on others who have chosen to volunteer their time to donate their blood or plasma.

Glucose can be measured in whole blood, serum or plasma. So blood glucose and plasma glucose can be used interchangeably. Both refer to how much sugar is measured in the blood. There is a small difference, however.

Glucose is a simple carbohydrate that serves as the primary source of energy for living organisms. Glucose levels are measured by blood and urine tests, and like any other body chemistry, it has normal and abnormal ranges.
