Technical Abstract: Neonatal hypocalcemia is defined as a total serum calcium concentration of <7 mg/dL or an ionized calcium concentration of <4 mg/dL (1mmol/L). In very low birth weight (VLBW) infants, ionized calcium values of 0.8 to 1 mmol/L are common and not usually associated with clinical symptoms. In larger infants and in infants of >32 weeks' gestation, symptoms may more readily occur with an ionized calcium concentration of <1 mmol/L.
