Glucose, Random, Serum
Use
The test is useful in diagnosing and managing diabetes mellitus and other carbohydrate metabolism disorders including gestational diabetes, neonatal hypoglycemia, idiopathic hypoglycemia, and pancreatic islet cell carcinoma. It helps to measure blood glucose levels to determine if they are within normal range, which is crucial for diabetes management and can also detect extreme conditions like hyperglycemia and hypoglycemia, potentially leading to serious health consequences.
Special Instructions
Not provided.
Limitations
Once blood is drawn, the cells in the blood begin to metabolize the glucose, causing concentrations to decrease at ambient temperature by 10% per hour. In serum separator tubes, glucose becomes stable after centrifugation. Inhibitors like fluoride can be used to slow glycolysis.
