Automated determination of serum ceruloplasmin activity with o-dianisidine dihydrochloride as substrate

An automated method for the enzymatic determination of ceruloplasmin with o-dianisidine dihydrochloride as substrate is described. The method enables the measurement of 30 samples per hour with a coefficient of variation (day-to-day) of 2.8%. Results correlate well (r equals 0.99 with those obtained by the corresponding manual method
