Benedicts – Urine:
Why Benedict’s Urine test?
CLINICAL INFORMATION :
Benedict’stest is used to test for simple carbohydrates. It detects reducing sugars (monosaccharides – glucose, galactose, and fructose and some disaccharides i.e combination of two monosaccharides sucrose) which have free aldehyde, alpha-hydroxy-ketones, hemiacetals, or ketones as their functional group. Other tests used are Fehling’s test, Tollen’s test, etc. Benedict’sreagent or solution(contains a complex mixture of sodium citrate (Na3C6H5O7), sodium carbonate (Na2CO3), and penta-hydrate of copper-II sulfate CuSO4.5H2O)is used as a quantitative test to detect the presence of glucose in urine. A positive test with Benedict’s reagent is shown by a color change from clear blue to brick red with precipitate. Once any reducing sugar gets detected in urine further tests have to be undergone. False-positive test results can also be obtained by the presence of ascorbic acid, homogentisic acid, and other reducing substances in the urine.
