When preparing blood specimens for Glucose testing, it is important to separate the serum and plasma from erythrocytes immediately after collection. Erythrocytes utilize glucose for energy. If left in contact with each other, the glucose readings will decrease enough to produce a false- normal result. The level of glucose present in the blood can drop by as much as 10% per hour left at room temperature.
