| 摘要 |
Ascorbic acid in a sample such as blood serum is quantitatively assayed by converting the ascorbic acid to dehydroascorbic acid with ascorbic acid oxidase and reacting the dehydroascorbic with a coupling substance such as phenylenediamine to produce a detectable product. The ascorbic acid oxidase and coupling substance can be combined to form a reagent composition which can be incorporated into integral multilayer elements to form a test element.
