Abstract
A method of determining calcium metabolism in a patient comprises the steps of administering radioactive calcium isotope 41Ca to the patient, allowing a period of time to elapse sufficient for dissemination and reaction of the radioactive calcium isotope 41Ca by the patient, obtaining a sample of the radioactive calcium isotope 41Ca from the patient, isolating the calcium content of the sample in a form suitable for precise measurement of isotopic calcium concentrations, and measuring the calcium content to determine parameters of calcium metabolism in the patient.
