Why This Test Is Done
Your healthcare provider may order this test if you have symptoms of high blood sugar (such as frequent urination, excessive thirst, or unexplained weight loss) or if you have a known condition like diabetes. It can also be used to monitor long-term blood sugar control in people with diabetes.
What to Expect Before the Test
You’ll need to collect all urine for a full 24-hour period, typically starting after you’ve emptied your bladder at midnight. Store the urine in a refrigerator and return it to your lab within 24 hours. Follow any specific instructions your provider gives you, such as avoiding certain foods or drinks.
What Happens During the Test
No special preparation is required beyond collecting urine samples. The lab will analyze the combined sample to determine the total glucose excreted over the day.
What the Results Mean
Results are usually reported as the total amount of glucose excreted in grams or milligrams per day. High results may suggest diabetes or poor glucose control, while normal results indicate typical 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 urine glucose levels can indicate diabetes mellitus or impaired glucose tolerance. This test helps diagnose diabetes, assess treatment effectiveness, or detect subtle metabolic disturbances. It’s particularly useful for monitoring long-term glucose control in chronic conditions.
