A Membrane Ultrafiltration Procedure for Determining Diffusible Calcium in Serum

Abstract A rapid, simple procedure is described for separating diffusible from proteinbound serum calcium by centrifugation through high-flux ultrafiltration membranes. The mean normal value for ultrafilterable calcium was 57.1% (range 52 to 61%) of the total serum calcium concentration.
