Determination of Serum Calcium by Means of Sodium Alizarinsulfonate

[摘要] A direct method is described for the determination of serum calcium, in which reaction with sodium alizarin sulfonate takes place under optimal conditions to produce a colored complex of calcium, the absorbance of which is read at 550 mµ. One variation in procedure, in which prior isolation of the calcium as the insoluble oxalate is made, is also described.
