Phosphate Test

Phosphate is a charged ion in the blood that contains phosphorus, which is critical for building and repairing bones and teeth, helping nerves function, and making muscles contract.  It works closely with calcium in the body and most phosphorus (85%) is stored in the bones.  The kidneys filter extra phosphate out of the body and it is then eliminated in urine.  The parathyroid gland controls the level of phosphate and calcium in the body, but several diseases or infections could disrupt the relationship between phosphorus and calcium.

Test Details
