Hypercalcemia in neonates is a condition characterized by an abnormally high level of calcium in the blood. It is defined as a serum calcium concentration greater than 10.8 mg/dL (2.7 mmol/L) in term infants and greater than 12 mg/dL in preterm infants. Given the critical role of calcium in various physiological processes, hypercalcemia can have significant implications for newborns.
