Glucose is usually not present in urine, because in the kidneys glucose is reabsorbed from the filtrate of glomerulus, across the tubular epithelium of proximal tubule into the bloodstream. Therefore, normal glucose range in urine is 0 mg/dL, or rarely up to 15 mg/dL. If higher than normal levels of glucose (0-15 mg/dL) is found in urine, then it can be suspected as diabetes, pregnancy, or renal glycosuria. Presence of glucose in urine was commonly tested to monitor diabetes in the past. Now, blood tests for glucose is easier than urine test. The glucose urine test may be done when there is suspect of renal glycosuria.
