Urine glucose
Urine glucose checks whether sugar is spilling into your urine. Normally the kidneys reclaim all of it.

Why it matters
The kidneys can only reclaim glucose up to a threshold, at a blood level of about 10 mmol/L. Above that, glucose overflows into urine, so finding it is a clue to high blood sugar.
What a result can mean
Lower than the range
No glucose is the normal result.
Higher than the range
Glucose in urine most often means blood sugar has been high, as in diabetes. It is expected with SGLT2-inhibitor diabetes medicines, which work by passing glucose into urine, and it can occur in pregnancy and with a naturally low kidney threshold.
What can help
A positive result is followed up with blood glucose and HbA1c. If those are normal, a low kidney threshold is usually harmless.
