Abstract: | Summary In 27 subjects with several disorders of calcium metabolism, the fractional intestinal absorption of47CaCl2 was rather poorly correlated with the urinary output of calcium or with the maximal increase of serum calcium after an oral
calcium load. Conversely, a good correlation was observed with the product of these parameters. We propose that this product
be used as an estimate of intestinal calcium absorption when a radioisotopic method is not available. |
