Albumin‐corrected calcium and ionized calcium in stable haemodialysis patients

Albumin-corrected calcium and ionized calcium in stable haemodialysis patients.

BACKGROUND It is ionized calcium that is physiologically active and under homeostatic control; however, total calcium is more conveniently measured. Formulae for correction of calcium to account for albumin binding have not been validated in a dialysis setting. METHODS We measured ionized calcium simultaneously with total calcium (t[Ca]), albumin, total protein and pH before dialysis in 50 st...

Usefulness and feasibility of measuring ionized calcium in haemodialysis patients

BACKGROUND Measuring blood calcium level is recommended in haemodialysis (HD) patients. The Kidney Disease Improving Global Outcomes position states that the measurement of ionized calcium (ICa) level is preferred, but in the clinical setting, due to technical difficulties, total calcium (tCa) level is preferred to ICa. AIM The aim of this study was to test the possibility of delayed ICa anal...

Ionized calcium

Actual ionized calcium (at actual pH) vs adjusted ionized calcium (at pH 7.4) in hemodialyzed patients.

typed double-spaced (including references) with conventional margins. The overall length is limited to five manuscript pages, including not more than one figure or one table. To the Editor: Ionized calcium is now the measurement of choice for evaluating calcium metabolic diseases (1, 2). Ionized calcium may be reported either as the actual ionized calcium, referred to the actual pH of the patie...
