Understanding Inorganic Phosphorus

Inorganic phosphorus measurements help diagnose and treat various disorders related to the parathyroid gland, kidneys, and vitamin D imbalance. The method for determining phosphorus levels in protein-free blood filtrates was first described by Fiske and Subbarow in 1925. They used ammonium molybdate and aminoaphtholsulfonic acid as a reducing agent. Later, ferrous sulfate, introduced by Summer, improved the process, allowing for better specificity in dealing with different types of phosphates.

In 1953, Taussky and Shorr enhanced the method further by using ferrous ammonium sulfate, which is more stable. Then, in 1957, Dryer, Tammes, and Routh increased the sensitivity of the reaction by measuring absorbance at 340 nm instead of the previously recommended 650 to 750 nm.

Methodology

The test is a modification of the method developed by Daly and Ertingshausen. In this method, inorganic phosphate reacts with molybdate to form a heteropolyacid complex. The use of a surfactant eliminates the need for a protein-free filtrate. The absorbance at 340/380 nm directly correlates with the Inorganic Phosphorus level in the sample.
