We report results for adjusted ionized calcium (at pH 7.4) and actual ionized calcium (at actual pH) in capillary blood from 183 patients with disorders of calcium metabolism (primary hyperparathyroidism, secondary hyperparathyroidism of malabsorption, primary hypoparathyroidism, Paget's disease, acromegaly, hypercalcemia of malignancy, osteoporosis, sarcoidosis, idiopathic hypercalciuria, and familial hypocalciuric hypercalcemia). The correlation and the equation for the linear regression between adjusted ionized calcium (y) and actual ionized calcium (x) were y = 1.011x + 0.005 mmol/L, r = 0.992, Sy,x = 0.021 mmol/L. Results were similar within each diagnostic group. Consistent agreement between adjusted and ionized calcium was observed in 96.7% of patients representing a variety of the most frequently encountered disorders of calcium metabolism. Thus we find adjusted ionized calcium to be as useful as actual ionized calcium for evaluation of patients with such disorders. Adjusted ionized calcium may therefore also be a logical choice for establishing agreement between laboratories for reference intervals in healthy adults.

Of eight patients with Paget's disease one had diarrhoea, steatorrhoea, impaired xylose absorption, and macrocytic anaemia due to folic acid deficiency, while another had diarrhoea and very low xylose absorption. In both patients jejunal biopsy was normal, and they responded to folic acid therapy with considerable increase in xylose absorption. Low xylose excretion was seen in three more patients, one of whom also had steatorrhoea. Thus malabsorption may be a systemic complication of Paget's disease of bone, possibly due either to secondary folate deficiency or to relative ischaemia of the bowel.
