Glucose (24-hour urinary collection)
This test measures the amount of glucose (sugar) excreted in your urine over a 24-hour period. It helps assess how well your body is handling glucose, which can be important for diagnosing or monitoring conditions like diabetes.

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 changes. It can also be used to monitor long-term glucose control in people with diabetes or kidney function in certain cases.
What to Expect Before the Test
You’ll need to collect all urine for a full 24-hour period, typically starting after midnight one day and ending the same time the next day. Use clean containers to store the urine samples. Follow your provider’s instructions carefully to ensure accurate results.
How the Test Works
The test measures the total glucose present in your urine over the 24-hour period. This is done through a specialized laboratory analysis that detects glucose levels in the urine sample collected.
What the Results Mean
Higher than expected glucose in urine may indicate poor glucose control, diabetes, or kidney issues. Lower than expected levels might suggest metabolic problems or medications affecting glucose metabolism. Always discuss results with your healthcare provider.
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.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Glucose in urine can reflect how well your body regulates blood sugar. Elevated levels may signal diabetes or other metabolic disorders, while consistently low levels may warrant further investigation into underlying conditions like hormonal imbalances or certain medications.
