Why This Test Is Done
Your healthcare provider may order this test to monitor blood sugar control, especially if you have diabetes or symptoms like frequent urination, excessive thirst, or unexplained weight loss. It can also be part of routine screening or during pregnancy to check for gestational diabetes.
How the Test Works
A small urine sample is collected, typically via a midstream clean-catch method or a timed 24-hour urine collection. The sample is then analyzed to detect glucose using a chemical reaction that produces a measurable result.
What to Expect Before the Test
No special preparation is usually needed, but you may be advised to avoid certain foods or medications if your provider specifies. For a 24-hour urine collection, follow instructions precisely to ensure accurate results.
Possible Results and Interpretation
A positive result (glucose detected) means your kidneys are not filtering glucose properly, which can happen if your blood sugar levels are consistently high. A negative result indicates no glucose was found in the urine.
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.
High urine glucose levels are strongly associated with diabetes mellitus, particularly type 1 or type 2. It may also signal other conditions like kidney dysfunction or reactive hyperglycemia (e.g., from stress, illness, or certain medications). Regular monitoring helps manage blood sugar and prevent complications like nerve damage, eye problems, or cardiovascular disease.
