Renal hypophosphatemia

What it means

Renal hypophosphatemia is defined as reduced serum phosphate (e.g., below 0.70 mmol/l) and an inappropriately high renal phosphate excretion.

Three primary mechanisms of hypophosphatemia exist: increased renal excretion, decreased intestinal absorption, and movement of phosphate from the extracellular to intracellular compartments. The initial step in diagnosis involves determining whether hypophosphatemia is renal or nonrenal.
