Why Is This Test Done?

Your healthcare provider may order this test if you have symptoms like frequent urination, excessive thirst, or unexplained weight changes. It’s also used to monitor kidney function or diagnose conditions like diabetes that affect glucose processing.

What to Expect Before the Test

You’ll need to collect all urine for 24 hours, starting right after you wake up. Store the urine in a refrigerator and bring the entire sample to your lab visit. Follow any specific instructions your provider gives you, such as avoiding certain foods or medications.

How the Test Works

The test measures the total glucose present in your urine. This is done using a specialized method that detects glucose levels in the collected sample over the full day.

What the Results Mean

Higher-than-normal results may indicate diabetes or kidney problems, while very low results could suggest malabsorption issues or certain metabolic disorders. Your results will be interpreted by your healthcare provider in the context of your overall health.

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.

Elevated urinary glucose can signal diabetes, where the body struggles to regulate blood sugar properly. It may also reflect kidney issues, such as nephrotic syndrome, where the kidneys fail to reabsorb glucose back into the bloodstream. Low results might indicate conditions like malabsorption syndromes or rare metabolic disorders.

Short name

24-Hour Urine Glucose

Frequently asked questions

What causes elevated urinary glucose levels?
Elevated urinary glucose is most commonly linked to diabetes, where the body either doesn’t produce enough insulin or can’t use insulin effectively. Other possible causes include kidney problems, such as nephrotic syndrome, or certain medications.
How is this test different from a standard blood glucose test?
Unlike a standard blood glucose test, which measures glucose levels at a single point in time, this test measures the total glucose excreted in urine over a full day. It provides a broader picture of how your body handles glucose metabolism.
Can I eat or drink anything before this test?
Yes, you can eat and drink normally before this test. However, follow any specific instructions your healthcare provider gives you, such as avoiding certain foods or medications that might affect the results.
