Pseudohyperphosphatemia due to contamination with heparin: A case for caution

According to the manufacturer's package insert, heparinized saline is buffered with phosphate solution, which contains approximately 105 mg/dl of phosphate. The concept of pseudohyperphosphatemia secondary to heparin flush contributing to preanalytical error does not receive due attention. [......

Zusammenfassung:According to the manufacturer's package insert, heparinized saline is buffered with phosphate solution, which contains approximately 105 mg/dl of phosphate. The concept of pseudohyperphosphatemia secondary to heparin flush contributing to preanalytical error does not receive due attention. [...]it is worth considering spurious hyperphosphatemia in the differential diagnosis of unexplained elevated phosphorus level with normal serum calcium.
