Figure 4 Indices to ascertain renal phosphorus wasting in hypophosphatemia.
1Falsely low values in severe hypophosphatemia. 2May be used across all ranges of TRP and falsely low values in severe hypophosphatemia. 3Limitations: (1) Ideally requires oral phosphorus Loading; (2) Nomogram established for adults - children have physiologically higher serum phosphorus levels; (3) Overestimates tubular maximum reabsorption of phosphate/glomerular filtration rate if TRP > 0.8; and (4) Falsely low values in severe hypophosphatemia. UPhosphate: Urinary phosphate; UCreatinine: Urinary creatinine; PPhosphate: Plasma phosphate, PCreatinine: Plasma creatinine; TP: Tubular phosphate; GFR: Glomerular filtration rate; TRP: Tubular reabsorption of phosphate; PO4: Phosphorus; TmP: Tubular maximum reabsorption of phosphate.
