WebTo prevent detrimental increases in phosphate, parathyroid hormone also has a potent effect on the kidney to eliminate phosphate (phosphaturic effect). Maximizes tubular reabsorption of calcium within the kidney. This activity results in minimal losses of calcium in urine. Vitamin D acts also to increase blood concentrations of calcium. Webphosphate concentration and the fractional reabsorption of phosphate (TRP). The 0´ 0± 2´ 0 scale is suitable for estimating values of TmP/GFR close to the normal range expressed in SI units (mmol/L), and the 0´ 0± 5´ 0 scale for values close to the normal range in mass units (mg/100mL).
