Why Is This Test Done?

Your healthcare provider may order this test to check for signs of diabetes, monitor blood sugar control in people with diabetes, or detect conditions like kidney problems that can affect how your body processes glucose. It can also help assess dehydration or other metabolic disturbances.

How Is the Test Performed?

A small urine sample is collected, typically via a clean-catch midstream or a timed 24-hour collection (if specified). The sample is then analyzed in a lab using methods like enzymatic or turbidimetric techniques to measure glucose concentration.

What Does a Positive Result Mean?

Positive results (glucose detected) in urine may indicate high blood sugar levels, often due to diabetes, but can also occur in other conditions like stress, infection, or kidney issues. Persistent glucose in urine without diabetes should be discussed with your provider.

What Are Common Causes of Abnormal Results?

Glucose in urine can result from uncontrolled diabetes, pregnancy (gestational diabetes), certain medications, or conditions affecting kidney function. Stress, infections, or recent eating may also temporarily cause glucose to appear in urine.

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.

Clinical Significance: Glucose in Urine

Frequently asked questions

Is it normal to have glucose in my urine even if my blood sugar is normal?
No, glucose in urine (glycosuria) is generally not normal unless there is a specific medical reason like pregnancy or certain medications. If you have no known condition, persistent glucose in urine should be evaluated by your healthcare provider to rule out diabetes or other metabolic issues.
Can I prevent glucose from appearing in my urine?
While you can’t prevent glucose from appearing in urine if you have diabetes, managing blood sugar levels through diet, exercise, and medication (if prescribed) can help reduce or avoid frequent occurrences. Avoiding excessive stress and infections may also help.
What should I do if my urine glucose test is repeatedly positive?
If your urine glucose test is repeatedly positive, discuss it with your healthcare provider. They may recommend additional tests, like fasting blood glucose or hemoglobin A1c, to assess your overall blood sugar control and determine if diabetes or another condition is present.
