Why This Test Is Done

Your healthcare provider may order this test if you have symptoms like frequent urination, excessive thirst, or unexplained weight changes. It can also be used to monitor glucose control in people with diabetes or kidney function in those with high glucose levels.

How the Test Works

You’ll collect all your urine over 24 hours in a special container. The sample is then tested in a lab to measure the total glucose present.

Sample Collection

To prepare, empty your bladder before starting. Collect every drop of urine for the full 24 hours, including overnight. Keep the container clean and refrigerate if needed. Avoid foods high in sugar or medications that may affect results.

What to Expect

No special preparation is usually needed, but follow your provider’s instructions carefully. You may need to use a timer or calendar to track urine collection times.

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

How abnormal results are interpreted and what conditions they suggest.

This test helps diagnose or monitor conditions like diabetes, kidney disease, or metabolic disorders. Elevated levels may indicate poor glucose regulation, while very low levels could suggest dehydration or other issues.
