Calcium is the most common mineral in the body - and one of the most important. It is essential for building and fixing bones and teeth, helping nerves to function, muscle contraction, blood clotting, and helping your heart to work.

The vast majority of calcium in your body is stored in bone. The rest is in your blood.

Our Calcium Blood Test checks the calcium level in your body that is not stored in the bones to see whether you have the expected level of calcium in your blood.
