Fehling A - Reducing Sugar Applications

0.1M CuSO4 in Na/K tartrate buffer provides standardized oxidation potential across diabetic urine screening and food chemistry workflows.

Clinical laboratories detect glycosuria through brick-red precipitate confirming hyperglycemia. Quantitative cuprous oxide prevents false positive reducing substances.

Quality control verifies copper concentration, tartrate stability, and precipitate formation. Alkaline stabilization prevents copper reduction artifacts.
