Why Is This Test Done?
Your healthcare provider may order this test to check for excessive sugar in your urine, which can occur if your body isn’t properly regulating blood sugar. It’s particularly useful for diagnosing or monitoring conditions like diabetes, kidney issues, or metabolic disorders.
What to Expect Before the Test
You’ll need to collect all urine for a full 24-hour period, typically starting after midnight and ending the next midnight. Drink plenty of fluids to help your body pass urine, but avoid sugary drinks or foods that could affect results. Follow your provider’s instructions carefully.
How the Test Works
The collected urine is analyzed to measure glucose levels. The test detects whether sugar is present in amounts beyond normal, which can indicate issues with how your body processes glucose.
What the Results Mean
Higher-than-normal glucose in urine may signal diabetes, kidney problems, or other metabolic conditions. Your provider will interpret results in the context of your overall health and symptoms. Normal results suggest your body is handling sugar appropriately.
Reference range
Fasting: 70-100 mg/dLN/A
Fasting for 8-12 hours required. Water is permitted. Avoid chewing gum and smoking before the test.
