Phosphate excretion
WebApr 27, 2024 · True hypophosphatemia can be induced by decreased net intestinal absorption, increased urinary phosphate excretion, or acute movement of extracellular phosphate into the cells. Spurious hypophosphatemia can be caused by interference of paraproteins or medications with the phosphate assay [ 1,2 ]. WebPhosphate excretion declines with failing renal function. Increased plasma phosphate levels are, however, usually not observed before severe renal insufficiency has developed because the kidney has a phosphate secretory reserve stimulated by FGF-23 and PTH.
