After Hermann Christian von Fehling (1812-85), Professor of Chemistry at Stuttgart, Germany.]Solution of copper sulfate, potassium tartrate, and sodium hydroxide used to test for sugar (especially glucose) in the urine, which, when present, turns the solution reddish.A solution used for detecting the presence of sugar in urine. There are two components: Fehling's I (a copper sulfate solution) and Fehling's II (a solution of potassium sodium tartrate and sodium hydroxide), which are kept separate until required for use. Boiling Fehling's solution (equal amounts of Fehling's I and II) is added to an equal volume of boiling urine; a yellowish or brownish coloration indicates the presence of sugar.A solution that includes a copper salt that can be readily reduced and is employed to detect the presence of sugar in urine."}
