Urine Sugar Test
Urine Sugar, A urine sugar test measures the amount of urine sugar in urine. A urine glucose test is a quick and simple way to check for abnormally high levels of glucose in your urine.
- Glucose or any other sugar is not normally excreted In healthy individuals.
- Glucose is completely reabsorbed by renal tubular epithelial cells.
- Rate of glucose absorption (Tubulas maximum for glucose): 350 mg/min.
- The renal threshold for glucose is 180 mg/dl Glycosuria: Excretion of glucose in the urine.
How to perform the Glucose test in Urine:
Benedict Test Principle:
- Sodium Citrate
- Sodium Carbonate
- Copper Sulphate
- Blue (Nil)
- Green (+)
- Yellow (++)
- Red (+++)
- Dark Red (++++)
Benedict Test Interpretation:
Glycosuria: Presence of glucose in Urine:
|Hyperglycemia glycosuria||Renal glycosuria, Fanconi Syndrome|
|Diabetes Miletus, Commonest cause|
Diseases of pancreas
|Due to a decrease in the glucose reabsorption|
The capacity of renal tubular cells
Decrease overall threshold
