ABSTRACT
We report two patients whose serum samples presented severe hyperphosphatemia due to their high blood lipid levels. The patients had no clinical complaints owing to hyperphosphatemia, and there was no other reason to explain these patients' hyperphosph atemic laboratory results. As a result of further sophisticated investigation, we revealed that their hyperphosphatemia was due to hyperlipoproteinemia and the method which was used to measure lipid profile. Therefore if a clinician encounters such a condition, he/she should consider hyperlipoproteinemia is a factor which may cause a misleading blood phosphorus level.
