Glucose (24-hour urinary collection)
This test measures the total amount of glucose found in your urine over a 24-hour period. It helps assess how well your body is handling glucose, which is important for managing blood sugar levels.

Why This Test Is Done
Your healthcare provider may order this test if you have symptoms of diabetes, such as frequent urination, excessive thirst, or unexplained weight loss. It may also be used to monitor blood sugar control in people with diabetes or other conditions affecting glucose metabolism.
What to Expect Before the Test
You will need to collect all urine produced in a 24-hour period, typically starting after midnight and ending the same day the next morning. Use a clean container to store the urine, and keep it refrigerated until you return it to the lab. Follow your provider’s instructions carefully to ensure accurate results.
How the Test Works
The test measures the total glucose excreted in urine, which reflects how much glucose your kidneys are filtering out. This can indicate whether your body is processing glucose efficiently or if there is excess glucose in your bloodstream.
What the Results Mean
Results are typically reported as the total amount of glucose excreted in grams or milligrams over 24 hours. High levels may suggest diabetes or other metabolic issues, while normal levels indicate effective glucose regulation.
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.
