From San Mateo, California, USA:

My 23 month old daughter had an episode of "spilling" a small amount of glucose into her urine at the same time she had a urinary tract infection several months ago. This week, she was vomiting and had a low-grade fever. Fearing she was having another UTI, we collected a urine sample and took it with us to the urgent care center. The urine test came back stating that she had a lot of glucose in her urine (greater than 1000). Upon doing a blood sugar test, however, it came back normal (81). (It was also normal the first time she had glucose in her urine.) Everyone seems stumped. What are other causes of glucose in the urine in a child her age? Are there known items that can cause a false positive? What should we be looking for? She does not appear to have any other problems.


If your child has had several normal blood sugars at the time sugar was found in the urine, she may have what is called renal glycosuria. This is usually a benign condition where glucose "spills" into the urine at normal blood sugar levels. Usually there are no other kidney problems and this does not lead to diabetes mellitus. Lead intoxication can also cause renal glycosuria.
