Phosphate In Blood
Content provided by Healthwise
Test Overview
A phosphate test measures the amount of the mineral phosphate in a blood sample. The body needs phosphate to build and repair bones and teeth, help nerves function, and make muscles contract. Most of the body's phosphate (about 85%) is found in bones. The rest of it is stored in tissues throughout the body.
The kidneys 
help control the amount of phosphate in the blood. Extra phosphate is filtered by the kidneys and passes out of the body in the urine. A high level of phosphate in the blood is usually caused by a kidney problem.
The amount of phosphate in the blood affects the level of calcium in the blood. Calcium and phosphate usually are present in opposite amounts: As blood calcium levels rise, phosphate levels fall. For this reason, phosphate and calcium levels are usually measured at the same time.
