It was first introduced as a method to detect reducing substances in urine by James B. Sumner and has since been widely used, for example, for quantifying carbohydrate levels in blood. It is mainly used in assay of alpha-amylase. However, enzymatic methods are usually preferred due to DNS lack of specificity.</span></p>
