Intended Use

For the quantitative in vitro determination of Inorganic Phosphorous in serum and urine. This product is suitable for use on the Hitachi 704, 717, 902, and 911/912.

Clinical Significance

The human body contains approximately one kilogram of phosphorous. The calcium phosphate salts which comprise the inorganic substance of bone account for approximately 80% of the total phosphorous content. The remainder is distributed throughout other cells of the body primarily as organic phosphorous in phospholipids and phosphoproteins. In serum most inorganic phosphorus exists in a free form with approximately 15% bound to protein. Abnormal serum phosphates are most commonly seen in kidney, bone and parathyroid diseases. Phosphate is usually measured in conjunction with serum calcium since each measurement is useful in the interpretation of the other.

Principle

Inorganic phosphorous reacts with ammonium molybdate in the presence of sulphuric acid to form a phosphomolybdate complex which is measured at 340 nm.
