Neonatal Hypocalcemia
Diagnosis of Neonatal Hypocalcemia
Total or ionized serum calcium level Diagnosis of neonatal hypocalcemia is by measurement of total or ionized serum calcium; ionized calcium is the more physiologic measurement, because it does not require correction for protein concentration and pH. Prolongation of the corrected QT interval (QTc) on ECG also suggests hypocalcemia.
