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

Specimen: serum

Fasting for 8-12 hours required. Water is permitted. Avoid chewing gum and smoking before the test.

Frequently asked questions

How often should I collect urine samples for this test?
Urine samples are usually collected every 2–4 hours over a full 24-hour period. Your lab may provide specific timing instructions based on your schedule. If you’re unsure, ask your provider or lab technician for guidance.
What should I do if I miss a urine sample?
If you miss a sample, try to collect it as soon as possible. If you’re unable to complete the full 24 hours, your lab may adjust the test protocol. Always inform your healthcare team if there are delays.
Can I eat or drink normally before this test?
Standard dietary restrictions may apply, but follow your lab’s instructions carefully. Some tests avoid high-sugar foods or liquids to prevent interference. If unsure, ask your provider or lab staff for clarification.
