The Rapid Determination of Calcium in Biologic Material

[摘要] A rapid procedure for the routine determination of calcium in serum and urine has been described. 0.1 ml. of serum is titrated directly with standard EDTA, using either a calcein-KCl mixture or a calcein-thymolphthalein-KCl mixture. The end point with either indicating mixture is sharp. Excellent agreement is shown with the oxalate isolation and permanganate titration procedure.
