Glucose Monitoring Profile (24-Hour Urine and Serum/Plasma Tests)
This test measures blood sugar (glucose) levels in both your blood and urine over a 24-hour period to help track how your body processes glucose, often used in diabetes management.
["This profile helps assess blood sugar control and identify patterns in glucose excretion."]

Why This Test Is Done
Your healthcare provider may order this test if you have diabetes or are at risk for it. It helps evaluate how well your body manages glucose over time, especially if you experience frequent high or low blood sugar levels, symptoms like excessive thirst or fatigue, or if you’re being monitored for diabetes-related complications.
What to Expect Before the Test
You’ll likely need to collect urine samples throughout the day (typically 24 hours) in a special container. Blood samples may also be taken from a vein in your arm. Follow any specific instructions your lab provides, such as avoiding certain foods or medications, to ensure accurate results.
What the Test Results Mean
Results may show patterns of glucose in urine (indicating excess sugar) and blood (reflecting current blood sugar levels). High urine glucose could signal poor control, while consistent blood glucose values help confirm stable diabetes management.
Common Causes of Abnormal Results
Elevated glucose in urine or blood may indicate uncontrolled diabetes, stress, infection, or certain medications. Low glucose (hypoglycemia) could stem from overmedication, skipping meals, or intense physical activity. Always discuss results with your doctor.
Reference range
Fasting: 70-100 mg/dLN/A
Fasting for 8-12 hours required. Water is permitted. Avoid chewing gum and smoking before the test.
