Phosphorus - Serum

Phosphorus - Serum


A phosphate test measures the amount of phosphate in a blood sample. Phosphate is a charged particle (ion) that contains the mineral phosphorus. The body needs phosphorus to build and repair bones and teeth, help nerves function, and make muscles contract. Most (about 85%) of the phosphorus contained in phosphate is found in bones. The rest of it is stored in tissues throughout the body. The kidneys help control the amount of phosphate in the blood. Extra phosphate is filtered by the kidneys and passes out of the body in the urine. A high level of phosphate in the blood is usually caused by a kidney problem.

Why it is Done

A phosphorus test ascertains the amount of phosphorous present in the blood and helps diagnose conditions known to cause abnormally high or low levels.

What is this test

A phosphorus blood test is ordered to analyze phosphorus levels in the blood. Phosphorus is the most abundant mineral found in the body and obtained mostly from food like milk, grains, and protein-rich foods. Phosphorus in the body is available in bones and teeth, and also exists in cells and tissues throughout the body.

Phosphorus is an important element and helps:

  • Formation healthy bones and teeth
  • Processes energy in the body
  • Supports muscle and nerve functioning
  • Reduces muscle pain after a hard workout
  • Growth, maintenance, and repair of all tissues and cells, and for the the production of the genetic building blocks, DNA and RNA
  • Helps to filter out waste in the kidneys
    Conditions such as diabetes, starvation, and alcoholism can cause levels of phosphorus in the body to fall. The body maintains phosphorus/phosphate levels in the blood by regulating how much it absorbs from the intestines and how much it excretes via the kidneys.
