Overview of Phosphorus, Serum

What is Phosphorus, Serum?

Phosphorus is an electrolyte that is present in blood as organic and inorganic phosphates (PO43-). It plays essential roles in the metabolism, pH & electrolyte balance, functioning of muscles and nerves, and maintenance of healthy bones. The Serum Phosphate Test measures the levels of inorganic phosphates in blood.

Sample Type

The sample type collected for Phosphorus, Serum is: Blood

Preparation for Phosphorus, Serum

  • Do not eat or drink anything other than water for 8-12 hours before the test.

Why Get Tested for Phosphorus, Serum?

The Phosphorus Test is performed:

    To evaluate phosphate levels in case of bone and kidney diseases
    To determine conditions associated with certain glands like parathyroid glands
    To determine the cause of abnormal levels of Vitamin D
   To monitor levels when taking phosphorus or calcium supplements



Understand more about Phosphorus, Serum

Phosphorus is both a mineral and an electrolyte, which is present in blood as organic and inorganic phosphates. Phosphates perform a number of essential roles in the body. It is critical in energy production and storage as it forms a part of the energy currency of cells (Adenosine tri, di, and monophosphates). It is also a structural component of DNA. It is essential in the functioning of nerves and muscles, and in the growth and maintenance of healthy bones. In blood, phosphates act as buffers to maintain the pH and electrolyte balance of the body.

Diet forms the main source of phosphorus. Once consumed, it is quickly absorbed by the digestive system. In the body, most of the phosphates are bound to the bones and teeth with calcium. Some of it is found in muscles and nerves, and a small amount in all cells where it forms a structural component of DNA and energy storage. Very small amounts of phosphates are normally found in circulation and these levels are measured with the serum phosphate test.

Phosphate levels in the blood are maintained within its very narrow normal concentration range by excretion of excess phosphorus through kidneys. Phosphate levels are also dependent on the levels of calcium, Vitamin D and Parathyroid Hormone in blood.


What Results of Phosphorus, Serum mean?

Interpretations

Normal range: 2.40 to 4.40 mg/dL

Phosphate concentration in the blood is maintained within a narrow normal range between 2.40 mg/dL and 4.40 mg/dL.

Hypophosphatemia or low blood phosphorus is indicated if phosphorus concentration lies below the normal range.

Hyperphosphatemia or high blood phosphorus is indicated if phosphorus concentration lies above the normal range.

Phosphate levels in children are usually higher than in adults due to the active growth of bones in children.


Patient Concerns about Phosphorus, Serum

Frequently Asked Questions about Phosphorus, Serum

Q. How is this test performed?
This test is performed on a blood sample. A syringe with a fine needle attached is used to withdraw blood sample from a blood vessel in your arm generally from the inner side of the elbow area. The doctor, nurse or the phlebotomist will tie an elastic band around your arm which will help the blood vessels to swell with blood and hence makes it easier to withdraw blood. You may be asked to tightly clench your fist. Once the veins are clearly visible, the area is cleaned with an antiseptic solution and then the needle is inserted into the blood vessel to collect the sample. You may feel a tiny pinprick during the procedure. Blood sample once collected is then sent to the laboratory.
Q. Is there any risk associated with this test?
There is no risk associated with the test. However, as this test involves a needle prick to withdraw the blood sample, rarely, a patient may experience increased bleeding, hematoma (blood collection under the skin) formation, bruising or infection at the site of needle prick.
