Atomic absorption spectrophotometry (AAS) was applied to the determination of serum calcium. A special diluent was developed to abolish the effect of absorption depressors. This made possible measurement of calcium in directly diluted serum samples without prior removal of any serum constituents. Values obtained by AAS on calcium oxalate precipitates from serum were identical with those found by the direct dilution technique.
