Phosphorus
Phosphorus is a mineral needed for bone and tooth structure, ATP energy production, and cell membrane phospholipids. High levels are typical in advanced kidney disease and hypoparathyroidism, while low levels can result from malnutrition, alcohol use, refeeding syndrome, or vitamin D deficiency and cause muscle weakness and bone pain. It is interpreted alongside calcium and PTH.
