Urine sugar test
Quick answer: This test checks urine for glucose (sugar), which normally does not appear in urine. It may be used to screen for diabetes or check sugar control, though blood glucose tests are more reliable.

What your results can mean
Reading your report
Sugar can appear in urine in normal pregnancy too, so a blood test is usually needed to confirm; discuss it with your doctor.
If the result is outside the usual range
Sugar in urine can be seen when blood sugar is high, as in diabetes or diabetes in pregnancy, and sometimes when the kidneys let sugar through at normal blood levels. Some diabetes medicines also pass sugar into the urine on purpose.
Who usually has this test
People with symptoms of diabetes, pregnant women at antenatal visits, and people having routine check-ups.
Risks and aftercare
There are no risks; a blood sugar test may follow if sugar is found.

Questions about this test
Can urine sugar diagnose diabetes?
No. Diabetes is diagnosed with blood tests, such as fasting glucose or HbA1c. Urine sugar is only a clue that suggests blood tests are needed.
Why is there sugar in my urine in pregnancy?
In pregnancy the kidneys can let some sugar through even when blood sugar is normal. Doctors confirm with a blood glucose test before diagnosing diabetes in pregnancy.
Can medicines cause sugar in urine?
Yes, a group of diabetes medicines called SGLT2 inhibitors works by passing sugar into the urine. Tell the staff about the medicines you take, and do not stop them on your own.
