Glucose is the primary energy source for the body’s cells and the only energy source for the brain and nervous system. This test may be used to screen for both high blood glucose(hyperglycemia) and low blood glucose (hypoglycemia), help diagnose diabetes, and to monitor glucose levels in persons with diabetes

Serum glucose has been found to be 2-5% higher than plasma glucose.

Spectrophotometry (SP)

Glucose levels may be depressed if sample is left to clot and not spun for an excessive length of time.

Reference Range(s)
65-99 mg/dL

Clinical Significance
