Reference Range:

70 - 99 mg/dL

 

Interpretive Data:

If this specimen was collected from a fasting patient, values of 100-125 mg/dL are considered impaired fasting glucose/"prediabetes", according to current ADA guidelines.
 

Critical Decision: 

0 years to 21 years ≤ 35 or ≥ 200 mg/dL

21 years and up ≤ 50 or ≥ 500 mg/dL

Note:  Critical values are called to the provider and communicated as critical.  Documentation of the call is recorded in the patient record.

Clinical Significance

Blood glucose may be abnormally high (hyperglycemia) or abnormally low (hypoglycemia). Hyperglycemia is seen in diabetes mellitus, Cushing’s syndrome, acromegaly and hypoadrenalism. Hypoglycemia: Transient neonatal hypoglycemia, leucine-sensitive hypoglycemia, islet cell adenoma, hypoadrenalism and liver disease. Glucose is the major energy source for the human body. Glucose determinations are ordered for the diagnosis and follow-up of abnormalities of carbohydrate metabolism.
