China Bio&Media Inorganic Phosphorus Test Kit Ivd Reagent

The inorganic phosphorus (PHOS) assay kit is intended for the accurate and direct quantitative measurement of inorganic phosphorus in human plasma. This test is mainly used in the diagnosis of renal dysfunction, bone disease and parathyroid disease.
Test principle
In an acidic environment, inorganic phosphorus reacts with ammonium molybdate, generating ammonium phosphomolybdate complex which shows absorption at the wavelength of 340 nm. The absorbance is proportional to the concentration of inorganic phosphorus.
