If the RTG is so low that even normal blood glucose levels produce the condition, it is referred to as renal glycosuria. Glucose in urine can be identified by Benedict's qualitative test. If yeast is present in the bladder, the sugar in the urine may begin to ferment, producing a rare condition known as urinary auto-brewery syndrome.
Renal glycosuria is a rare condition in which the simple sugar glucose is excreted in the urine [1] despite normal or low blood glucose levels. With normal kidney (renal) function, glucose is excreted in the urine only when there are abnormally elevated levels of glucose in the blood.

Automatic analysis of urine test strips using automated urine test strip analysers is a well-established practice in modern-day urinalysis. They can measure calcium , blood, glucose, bilirubin, urobilinogen, ketones, leukocytes, creatinine , microalbumin , pH, ascorbic acid and protein.
Test strips for glucose contain the enzyme glucose oxidase, which breaks down glucose and forms hydrogen peroxide as a byproduct. In the presence of a peroxidase enzyme, hydrogen peroxide reacts with a chromogen to induce a color change. [51] The presence of glucose in the urine is known as glycosuria.
Abnormal kidney function may cause too much or too little urine to be produced. The ability of the kidneys to filter protein is often measured, as urine albumin or urine protein levels, [2] measured either at a single instance or, because of variation throughout the day, as 24-hour urine tests.

Protein loss in the urine due to damage of the glomeruli may become massive, and cause a low serum albumin with resulting generalized body swelling (edema) so called nephrotic syndrome. Likewise, the estimated glomerular filtration rate (eGFR) may progressively fall from a normal of over 90 ml/min/1.73m 2 to less than 15, at which point the ...
Renal glucose reabsorption is the part of kidney (renal) physiology that deals with the retrieval of filtered glucose, preventing it from disappearing from the body through the urine. If glucose is not reabsorbed by the kidney, it appears in the urine, in a condition known as glycosuria. This is associated with diabetes mellitus. [1]
