Abstract
THE investigation of the accuracy of determination of serum magnesium1, criticized by Alcock et al. in the preceding communication, was undertaken to establish the normal serum magnesium concentration on the basis of accepted procedures of analytical chemistry2. The considerations governing this investigation were given in detail. The accuracy of the standards was validated using certified National Bureau of Standards materials; serum magnesium concentration was then measured by two entirely different methods and the same values were obtained; finally, recovery of added standards by both methods approached 100 per cent.
