57796-5Reducing substances [Presence] in Stool by Post hydrolysisActive

Term Description

This term represents the stool reducing substance assay after the addition of HCl, which hydrolysis sugars that are not typically reducing, such as sucrose, and converts them into a reducing form. Typical reducing substance assays [LOINC:11060-1] detect reducing substances in stool without (or before) the addition of HCl, and therefore do not detect non-reducing sugars such as sucrose.

Part Description

LP15040-6   Reducing substances
A reducing sugar is any sugar that, in basic solution, forms an aldehyde or aketone. This allows the sugar to act as a reducing agent as in the Maillard and Benedict's reactions. Reducing sugars include glucose, fructose, glyceraldehyde, lactose, arabinose and maltose. All monosaccharides which contain ketone groups are known as ketoses, and those which contain aldehyde groups are known as aldoses. Sucrose and trehalose are not reducing sugars.

Change Reason
The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016.
