A development of a technique for estimating sugar in blood, cerebrospinal fluid, etc., is described, using 3:5-dinitrosalicylic acid (D.N.S.A.) originally introduced by Sumner (1921). Results can be obtained less than 10 minutes if required. The method well suited to the estimation random blood sugars and handling diabetic clinic requirements hospital laboratories. reagents are cheap, stable, easily prepared. results very close true glucose values fluid. has justified its existence busy clinical laboratory on grounds simplicity rapidity, sufficiently precise all ordinary work.
