INTRAVENOUS VITAMIN D IN THE DETECTION OF VITAMIN-D DEFICIENCY

The Lancet, 1969
Abstract Forty-three patients, mostly with gastro-intestinal disorders, were each given 1 mg. vitamin D 3 intravenously. The mean change in the fasting serum-phosphate on the fourth and fifth days after vitamin D was expressed as a percentage of the basal level. In thirty-two patients the change in serum-phosphate did not exceed the control range of ±
