SERUM CALCIUM IN A GERIATRIC INPATIENT POPULATION
Norihwick Park Hospital and Clinical Research Centre Harrow, Middlesex
Serum calcium was studied in an inpatient series of 594 elderly subjects. A normal range was obtained which was similar to published adult ranges after adjustment for protein differences. No sex difference or correlation with age was found. The commonest cause of hypocalcaemia appeared to be cation-losing renal failure whilst osteomalacia accounted for only a quarter of cases and many osteomalacias had calcium values within the normal range. Hypercalcaemia seemed to be mainly due to dehydration; a substantial group was due to malignant disease, and hyperparathyroidism was an infrequent cause.
