Test Code =GLU Glucose Level For Blood Gas Syringe

Important Note

This test is for glucose level using a Heparinized Syringe.

Clinical System Name

Glucose Level

Synonyms

Sugar (Glucose) - Blood

= GLU

Glucose Level, Syringe

Description

Fasting plasma glucose concentrations and tolerance to a dose of glucose are used to establish the diagnosis of diabetes mellitus and disorders of carbohydrate metabolism. Glucose measurements are used to monitor therapy in diabetics and in patients with dehydration, coma, hypoglycemia, insulinoma, acidosis, and ketoacidosis.
