Understanding Phosphorus, Serum


What is Phosphorus, Serum?

A phosphorus serum test can determine whether you have high or low phosphorus levels in the blood. Phosphorus is a mineral needed to build strong bones and teeth as well as nerve signaling and muscle contraction.

The serum phosphorus test is done to evaluate phosphate levels in case of bone and kidney disease, to determine the cause of the abnormal level of Vitamin D, and to monitor levels while taking phosphorus and calcium supplements.

Excess phosphorus can indicate impaired kidney function, while low phosphorus levels may be due to malnutrition and lack of Vitamin D.

   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
