Test Indications:
|
Glucose is derived from the breakdown of carbohydrates in the diet and in the body stores. The glucose level in the blood is maintained within a narrow range by regulatory hormones such as insulin, glucagons, or epinephrine. The most frequently encountered disorder of carbohydrate metabolism is high blood sugar due to diabetes mellitus. Hypoglycemia is a blood glucose concentration below the fasting level.
