Version 2.77

Term Description

This term represents typical reducing substance assays that detect reducing substances in stool without (or before) the addition of HCl. These assays do not detect sugars that are not reducing, such as sucrose. A different code [LOINC: 57796-5] represents the stool reducing substance assay with the addition of HCl, which hydrolyzes sugars that are not typically reducing and converts them into a reducing form.

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.
