| Clinical Information: |
Urinary excretion of phosphate varies greatly with intake.
88% of the phosphorous contained in the body is localized in bone in the mineral form hydroxyapatite. The remainder is involved in carbohydrate metabolism or as a constituent of phospholipids, nucleic acids and ATP. Phosphate determination is useful in the diagnosis and management of a variety of disorders including bone, parathyroid and renal disease. |
