Ionized Calcium or Corrected Total Calcium?

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...

comparative evaluation of corrected qt and ionized calcium in children

convulsion is one of the most common problems in children and hypocalcemia is one the most frequent etiological items in children’s convulsion. corrected qt (qtc) in ekg is prolonged in hypocalcemia, so it can be a useful tool for evaluation of serum ionized calcium. in three groups (first seizure, multiple seizures, without seizure or control ) every 25 cases, qtc, serum ionized ca, total ca, ...
