Why This Test Is Done

Your doctor may order this test if they suspect conditions like diabetes, kidney problems, or abnormal sugar metabolism. It can also help monitor long-term glucose control in people with diabetes or other metabolic disorders.

What to Expect Before the Test

You’ll need to collect all urine for 24 hours, starting and ending with a sample at the same time each day. Store samples in a refrigerator and bring the entire collection to your lab. Follow any specific instructions your healthcare provider gives you to ensure accurate results.

How the Test Works

The test measures the total glucose present in your urine, which is collected in a sealed container. The sample is analyzed in the lab using a method that detects glucose levels, often through a chemical reaction or specialized equipment.

What the Results Mean

Higher-than-normal results may indicate diabetes, kidney problems, or other metabolic conditions. Lower-than-normal results might suggest conditions like dehydration or certain hormonal imbalances. Your doctor will interpret the results in the context of your overall health and medical history.

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.

Abnormal results can signal underlying health issues, such as uncontrolled diabetes, kidney dysfunction, or conditions affecting glucose metabolism. Regular monitoring of urinary glucose can help manage chronic conditions and prevent complications.
