Urine Glucose — What It Means in Your Urine Test
New to reading lab reports? Start with our guide to reading a blood test report
This checks whether sugar is spilling into your urine, which can happen when blood sugar runs high.
Urine Glucose simply asks whether any sugar has ended up where it usually should not. When it shows up, it often mirrors what your body is doing with sugar overall, and your doctor can help make sense of it.
Also known as: Glucosuria, Glycosuria, Urine sugar, Glucose (urine)
This isn't a case where higher or lower is better. Your body keeps it in a narrow band, and both directions can matter.

What is Urine Glucose?
A chemically treated test strip reacts with any glucose that reaches the urine, producing a colour that estimates the amount. Normally the kidneys reabsorb glucose so none escapes.
Why is Urine Glucose tested?
It is checked to look for sugar spilling into the sample. This tends to occur once blood sugar rises above what the kidneys can hold back.
What is a normal Urine Glucose range?
- India
- No India-specific national reference interval is published for this parameter; your lab's printed range is the most reliable comparison.
- Global
- Negative
Ranges vary by lab, method and equipment — the range printed on your own report is the one that applies to your result.

What does a high Urine Glucose result mean?
A positive result may mean your blood sugar rose high enough to spill into the urine. Sometimes the kidneys let sugar through at a lower level than usual.
What does a low Urine Glucose result mean?
A negative result is the usual normal finding. It means your kidneys are holding on to sugar as they should.
