Also Known As: P, PO4, Phosphate

Phosphorus is a mineral that combines with other substances to form organic and inorganic phosphate compounds. The terms phosphorus and phosphate are often used interchangeably when talking about testing. Still, the amount of inorganic phosphate in the blood is measured with a serum phosphorus/phosphate test.

Phosphorous tests are used to evaluate the mineral level in your blood and aid in diagnosing conditions known to cause abnormally high or low levels of phosphorus.
