Ultradian variation in serum phosphate concentration in patients on haemodialysis
To study how much the serum phosphate concentration could vary on the day before scheduled dialysis we obtained 24–37 timed measurements during 24 h in nine patients on maintenance haemodialysis. During the observation there was an increase in serum phosphate concentration of 0.239 ± 0.022, P/

Five of the nadirs occurred at 11.40−14.50, mean 12.59, and three at 19.00−21.30, mean 20.00. We found no coinciding changes in the serum calcium concentration.
