Phosphorus is a mineral element that is needed to make inorganic phosphates in the body. Inorganic phosphates are needed for energy production, nerve function, bone growth and maintenance of muscle. It also acts as a buffer to maintain the body’s acid-base balance. A phosphorus blood test is used to determine the amount of inorganic phosphates in the body, and is ordered along with calcium, parathyroid hormone and vitamin D. This test can help in the diagnosis of calcium, phosphorus and acid-base imbalances.
