We found that 13 of the 17 laboratories (76%) analyzed reducing substances as a reflex screening test for urine from pediatric patients. The age at which the reflex testing was performed varied from <6 months (2/17) to no age restrictions (2/17).

Their presence frequently reflects dietary consumption but can indicate specific pathology if either a particular saccharide or a particular excretory pattern is present. Most saccharides (except glucose) have low renal thresholds and are readily excreted in the urine.

Detection of reducing substances in urine has been a standard laboratory procedure for about 50 yr. It is used as a screening test for inborn errors of carbohydrate metabolism.

2005年10月21日 · Detection of reducing substances in urine has been a standard laboratory procedure for about 50 yr. It is used as a screening test for inborn errors of carbohydrate metabolism.

2023年3月13日 · Glycosuria is a term that defines the presence of reducing sugars in the urine, such as glucose, galactose, lactose, fructose, etc. Glucosuria connotes the presence of glucose in the urine and is the most frequent type of glycosuria, which is the focus of this review.

For more than 50 years the detection of reducing substances in urine has been a standard laboratory procedure. For the inborn errors of carbohydrate metabolism, it is used as a screening test. Specifically for screening galactosaemia (galactosuria), this test is performed.

Benedict’s test is a non-specific method used to screen urine for the presence of reducing substances. A similar test is incorporated into Clinitest tablets. Principle. Benedict’s test relies on the reduction of soluble blue cupric ions (CuSO4) in a heated, strongly alkaline solution.

2012年4月2日 · Detection of non-specific reducing substances in urine was begun more than 50 years ago as a screening test for inborn errors of carbohydrate metabolism in pediatric patients.

Results: Out of carefully selected 383 cases, 59% (226) were positive for reducing sugars in their urines. 14% were Glucosurics and 86% as Lactosurics. Lactose in the urine of infants was corresponding to.

2005年2月3日 · This is a screening test to detect various substances in the urine that chemically react with an indicator metallic dye called cupric sulfate. The most common reducing substances examined include glucose or galactose. How the test is performed. Collect a “clean-catch” (midstream) urine sample.
