| Abstract: | An enzymatic assay of D -3-hydroxybutyrate in which the hydroxybutyrate dehydrogenase reaction is coupled to the bacterial oxidoreductase—uciferase system is described. The bioluminescent assay is based on either, end-point, or on initial velocity measurements. This simple and rapid assay requires a single serum sample of 10 μl. Its linear range covers two orders of magnitude from 10?6 mol/I upwards. This assay is suitable for the routine determination of D -3-hydroxybutyrate in human blood with good accuracy. |
