About This Test
Phosphorus works closely with calcium to build and maintain healthy bones and teeth, and it also plays a role in nerve signaling and muscle contraction. Because your kidneys help regulate phosphorus levels, this test can help evaluate kidney function, since levels can rise when the kidneys aren't filtering effectively. It's also commonly ordered alongside calcium testing, either to follow up on an abnormal calcium result or to help investigate symptoms like fatigue, muscle weakness, or bone problems.
