ALB and Hypocalcemia: The aim of this study was to evaluate the utility of ionized calcium (iCa) measurements with a point-of-care ionometer compared to albumin-corrected total calcium and to assess the incidence of hypocalcemia in patients receiving etelcalcetide therapy using pre-dialysis iCa values.<h4>Materials and methods</h4>This was a phase IV, non-interventional, prospective, single-arm, observational study.
