Why Is This Test Done?

Your healthcare provider may order this test to check how well your kidneys are working, especially if you have symptoms like frequent urination, excessive thirst, or signs of diabetes. It can also help monitor conditions like diabetes or kidney disease.

What to Expect Before the Test

You’ll need to collect all your urine for 24 hours, starting and ending with a sample at the same time each day. Drink plenty of fluids but avoid sugary drinks or foods that might affect results. Follow your provider’s instructions carefully.

How the Test Works

The test measures the total glucose present in your urine over a full day. This helps determine if your kidneys are properly filtering glucose, which can indicate how well your body manages blood sugar levels.

What the Results Mean

Higher than expected amounts of glucose in urine may suggest diabetes, kidney issues, or other metabolic problems. Your results will be compared to your individual baseline and clinical context by your healthcare provider.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

This test is particularly useful for diagnosing or monitoring conditions like diabetes mellitus, nephrogenic diabetes insipidus, or other metabolic disorders that affect glucose metabolism and renal function. It can also help assess kidney function in patients with suspected urinary tract abnormalities.

How often should I get this test?
Your provider will determine how often you need this test based on your health condition, symptoms, and medical history. Regular monitoring may be recommended if you have diabetes, kidney disease, or other related conditions.
Can diet or medications affect this test?
