An automated method for determining serum albumin with bromcresol green according to Doumas et al. [C/in. Chim. Acta 31, 87 (1971)] was simplified and improved for use in routine analysis. The manifold is simpler, there is better sample separation and less sample interaction, both within-run and day-to-day run precision are excellent, and results agree well with those obtained by electrophoresi...
