What are the normal phosphorus levels in blood?

November 22, 2011

Before we talk about normal phosphorus levels in blood, let us explain the importance of phosphorus in our bodies. Phosphorus is a mineral that is found in our bodies and it helps to build strong healthy bones as well as keep other parts of the body healthy. Phosphorous helps to maintain the normal functioning of the nerves as well as the contractions of the muscles. Excess phosphorous in the body is removed by the kidneys. However, if the kidneys are damaged, they are unable to remove this excess phosphorous which could lead to further health problems and complications. Therefore the definition of normal phosphorous levels in blood is determined by whether you have chronic kidney disease (CKD) in the early stages or if you are on dialysis. Normal phosphorous levels in blood for people who do not suffer from kidney disease and for those who have CKD non dialysis is 2.7 to 4.6 mg/dL (milligrams per deciliter). Normal phosphorus levels for patients who are on dialysis are 3.5 to 5.5 mg/dL. A phosphate test is usually recommended to check for the proper functioning of the parathyroid glands, bones and functioning of the kidneys. The normal phosphorous levels in the blood for children are 4.5 to 6.5 mg/dL.

As can be seen from the information given above, abnormal phosphorus levels in blood are a cause for concern for people who suffer from kidney disease and are on dialysis. Higher levels than the ones given above could result in death for dialysis patients. Research has shown that abnormal phosphorus levels in blood lead to a 20% to 40 % risk of death in dialysis patients.

Elevated or higher than normal levels could indicate Hypoparathyroidism, bone metastasis, liver disease, diabetic ketoacidosis, Hypocalcaemia, renal failure, too much Vitamin D, Sarcoidosis and so on. High phosphorus levels also lead to calcium deposits in the lungs, eye, heart and blood vessels which is dangerous. Abnormally high levels of phosphorus in the blood can lead to organ damage due to calcification.

Low phosphorus levels in blood are indicative of Hypercalcemia, especially due to hyperparathyroidism, hypothyroidism, chronic antacid use, malnutrition, severe burns, the overuse of diuretics, alcoholism, diabetic ketoacidosis (after treatment) , rickets and osteomalacia (which are due to Vitamin D deficiencies).

Phosphorus tests may be ordered along with other tests as well if symptoms point to gastrointestinal or kidney disorders. If your phosphorus levels are high your doctor will recommend a low phosphorus diet and maybe phosphorus binding medication as well.
