Phosphorus is an essential mineral that works closely with calcium to keep your bones and teeth strong and to support energy use in cells. The kidneys and certain hormones help keep its level steady. The phosphorus blood test measures the level of this mineral. It helps doctors check bone health, kidney function, and the balance of minerals in the body.
