Editing Hyperphosphatemia (section)

===Units===
Phosphates in blood exist in a [[chemical equilibrium]] of hydrogen phosphate (HPO<sub>4</sub><sup>2–</sup>) and dihydrogen phosphate (H<sub>2</sub>PO<sub>4</sub><sup>–</sup>), which have different [[mass]]es. Phosphate (PO<sub>4</sub><sup>3–</sup>) and [[phosphoric acid]] (H<sub>3</sub>PO<sub>4</sub>) are not present in significant amounts. Thus [[millimoles]] per liter (mmol/L) are often used to denote the phosphate concententration. If milligrams per decililiter (mg/dL) is used, it often denotes the ''mass of phosphorus'' bound to phosphates, but not the mass of some individual phosphate.<ref>{{Cite book|title=Nephrology secrets|vauthors=Lerma EV|year=2019|isbn=9780323478717|edition=4th|pages=532–533|publisher=Elsevier |display-authors=etal}}</ref>
