Hi, my 2.5 year old daughter has tested positive for sugar in her urine but blood sugar is normal, all other blood tests at our local hospital have also come back normal. We are now being referred to a specialist to figure out why her kidney is leaking glucose into her urine. Any idea what would cause this? Thanks
Hi...the possibilities could be a test being taken after exercise too. Sugar in the urine is usually checked only as a back-up to checking blood sugar, or to screen other family members. A urine check showing no sugar means that when the urine was made the blood sugar level was below the renal (kidney) threshold (about 8.0 to 12.0 MML/L, or 145 to 220 mg/DL). A urine check showing sugar means that when the urine was made, the blood sugar was above the renal threshold. These urine checks are not a direct measure of blood sugar, because the urine collected for the test may have been produced over a number of hours. Regards -
