A quantitative assay for 1,5-anhydroglucitol in a specimen is described. This assay comprises treating a specimen with a phosphorylating enzyme in the presence of 5 to 500 mM adenosine-5'-triphosphate in a pH range of 7.2 to 8.5, to selectively eliminate sugars other than 1,5-anhydroglucitol, and reacting the product of this reaction, without removing the residual ATP, with pyranose oxidase in the above pH range. This assay is quite rapid and suitable for performance using an automated device. |
