A small amount of glucose in your urine is normal. If a random urine sample shows more than 0.25mg/ml, this is considered glycosuria and can be caused by too high blood glucose levels, a problem with your kidney filters, or both.

A glucose in urine test may be part of a urinalysis, a test that measures different cells, chemicals, and other substances in your urine. Urinalysis is used to check your general health.
