What is the threshold for hypercalcemia in neonates?

In neonates, hypercalcemia is typically defined as total serum calcium exceeding 10.8 mg/dL. This threshold is significant because while calcium is essential for various physiological functions in neonates, elevated levels can lead to various health complications. These can include issues related to the cardiovascular system, kidneys, and nervous system, as excess calcium can result in calcification of soft tissues and potential damage to organs.

Monitoring and managing calcium levels is crucial in neonates, especially those who are premature or have underlying health conditions, as they might be at higher risk for dysregulation of calcium metabolism. Thus, understanding the specific threshold for hypercalcemia helps healthcare providers assess and intervene appropriately for the safety and well-being of their patients.
