What is the normal range for serum phosphorus levels in neonates?

The normal range for serum phosphorus levels in neonates is indeed 4-7 mg/dL. Phosphorus is a critical mineral in the body that plays essential roles in energy production, cellular repair, and the formation of bones and teeth. In neonates, maintaining an appropriate level of phosphorus is crucial because they are in a rapid growth phase and have high metabolic demands.

The specified range encompasses the typical values observed in healthy neonates, ensuring adequate support for their physiological needs. Values below this range might indicate hypophosphatemia, which can affect various bodily functions, including bone health and energy metabolism. Conversely, levels significantly above this range could lead to hyperphosphatemia, potentially resulting in complications such as calcification of soft tissues.

Understanding the normal range for serum phosphorus levels empowers healthcare providers to assess and manage electrolyte balance in neonates effectively, thereby ensuring optimal health outcomes in this vulnerable population.
