title: The effect of oral calcium-loading test on the distribution of urinary phosphates in healthy and hypercalciuremic children.
abstract: The distribution of inorganic phosphate ions in urine is calculated with known stability constants, measured pH and electrolyte concentrations. The distribution of phosphate ions in the urine of healthy children is considerably different from that of hypercalciuremic children. Before and after oral calcium-loading test, the most significant difference is in the molar fraction of CaHPO4.
