Spurious hyperphosphatemia due to hyperlipidemia.
A patient had hyperlipidemia associated with apparent hyperphosphatemia. Further tests on his serum and on the lipemic sera from 15 additional patients revealed a method-dependent overestimation of inorganic phosphorus values. The degree of overestimation was found to correlate positively with the serum triglyceride concentration. Unexplained elevation of the serum phosphorus level should alert the physician to the possibility of spurious hyperphosphatemia due to hyperlipidemia.
