Glucose, 24-Hour Urinary Excretion (Total)
This test measures the total amount of glucose (sugar) excreted in your urine over a 24-hour period. It helps assess how well your body is handling glucose metabolism.
["This test helps identify if your body is losing too much sugar through urine, which may indicate diabetes or other metabolic conditions."]

Why This Test Is Done
Your doctor may order this test if you have symptoms like frequent urination, excessive thirst, or unexplained weight changes. It can also be used to monitor long-term glucose control in people with diabetes.
What to Expect Before the Test
You’ll need to collect all urine for 24 hours, typically starting after midnight one day and ending the same time the next day. Store the urine in a refrigerator to keep it fresh until testing.
How the Test Is Performed
The test involves collecting urine samples throughout the day and combining them into a single container. The sample is then sent to a lab for analysis using a method like enzymatic or chemiluminescent immunoassay to measure total glucose content.
Possible Results and Interpretation
Results are reported as the total amount of glucose excreted in grams or milligrams over 24 hours. Higher than expected amounts may suggest diabetes or other conditions affecting glucose metabolism.
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.
Elevated urinary glucose excretion can indicate impaired glucose tolerance, diabetes, or conditions like renal glucose reabsorption defects. Low results may suggest normal glucose handling or conditions like insulin resistance that don’t cause urinary glucose loss. Always discuss results with your healthcare provider for personalized interpretation.
