title: [Quantitative determination of enteral calcium resorption with enriched stable 46Ca (author's transl)].
abstract: The application of a Ca-resportion test without the use of radioisotopes, which can therefore be used for babies, children and pregnant women, was investigated on 14 adult patients. In place of a radioisotope, an enriched form of the stable isotope 46Ca was administered orally, and the proportion of the applied dose of 46Ca appearing in the serum and urine was measured. 46Ca was measured by neutron activation over 47Sc. The clinical picture showed a close correlation with the determined resorption capacities. On the basis of the results, patients were classified into three groups: those with normal, increased, and decreased Ca-resorption.
