PRINCIPLE
Phosphate ion reacts with molybdate to produce phospho-molybdate, which is finally reduced to molybdenum blue, which is photometrically measured.
DIAGNOSTIC USE
Serum phosphate concentration, together with serum calcium concentration, is determined by the equilibrium that occurs between the absorption and excretion by the kidneys and the intestine and formation of bone tissue and cellular metabolism. Approximately 85% of the phosphorus in the body is in bone and teeth. High levels of phosphorus are found in cases of renal failure, hypoparathyroidism and vitamin D intoxication. Lower than usual values can be found in patients with alcoholism, or subject to
parenteral nutrition. Single test result could not be used to make a clinical diagnosis. It should integrate clinical and laboratory data.
