Why This Test Is Done

Your healthcare provider may order this test if you have symptoms of diabetes (like frequent urination, excessive thirst, or unexplained weight loss), if you have a family history of diabetes, or if you’re at risk due to other health conditions. It can also help monitor how well a diabetes treatment plan is working.

What to Expect Before the Test

You’ll need to collect all urine for a full 24-hour period, typically starting after you wake up in the morning. Store the urine in a refrigerator to keep it fresh. Bring all the collected urine to your lab appointment.

How the Test Works

The test measures the total glucose present in your urine, which is then analyzed to determine your daily excretion levels. This helps assess how much glucose your kidneys are filtering out.

What the Results Mean

Higher-than-normal results may suggest diabetes or impaired glucose tolerance, while very low results could indicate conditions like severe dehydration or certain medications affecting glucose metabolism.

Reference range

Fasting: 70-100 mg/dLN/A

Specimen: urine

Fasting for 8-12 hours required. Water is permitted. Avoid chewing gum and smoking before the test.

Clinical interpretation

Frequently asked questions

What does a high urine glucose level indicate?
High urine glucose levels often indicate diabetes or insulin resistance, where your body struggles to regulate blood sugar properly. This can lead to long-term complications like nerve damage, kidney issues, or cardiovascular problems if untreated.
What does a low urine glucose level indicate?
Low urine glucose levels may suggest dehydration, certain medications that reduce glucose excretion, or rare metabolic disorders. It’s less common but can also indicate how well your kidneys are filtering glucose normally.
How often should I get this test?
Your doctor will determine how often you need this test based on your medical history, symptoms, and treatment plan. Regular follow-ups may be recommended if you have diabetes or other metabolic conditions.
