Why Is This Test Done?

Your healthcare provider may order this test to check for signs of diabetes, kidney function, or other metabolic issues. It can also help monitor blood sugar levels in people with known diabetes or prediabetes.

What to Expect Before the Test

No special preparation is needed. You may be asked to collect a urine sample in a clean container at home or during a visit to a lab. If done in a clinic, a healthcare professional will guide you through the process.

How the Test Works

The test uses a chemical reaction (likely enzymatic or turbidimetric) to detect glucose in your urine. A positive result indicates the presence of glucose, which may signal high blood sugar levels.

What the Results Mean

Results are typically reported as positive (glucose detected) or negative (no glucose detected). Elevated glucose in urine may suggest diabetes or other conditions affecting blood sugar regulation.

Reference range

Fasting: 70-100 mg/dLN/A
