The pattern of calcium excretion was studied in 27 patients with successful renal allografts functioning for periods ranging from half a month to 39 months. Diminished 24‐hour calcium excretions and urinary calcium/creatinine ratios were found consistent with the reduced state of renal function. However, in half the patients, calcium output expressed as excretion per 100 ml GF was found to be low. High doses of steroids, hypercalcæmia and diuretics did not appear to affect this hypocaiciuria. Also, over 39 months no change in the pattern of calcium excretion was noted. A generalized hypophosphatæmia relative to a diminished GFR was also found. This was associated with hypercalcæmia in seven out of 21 patients. The possible mechanisms of these abnormalities are discussed.
