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 the heart to work. The vast majority of calcium in the body is stored in bone while the rest can be found in the blood. This calcium blood test checks the calcium level in the body that is not stored in the bones.
A high level of calcium (hypercalcaemia) could mean a benign (not cancerous) tumour on the parathyroid gland, a cancer that has spread to the bones, tuberculosis, a kidney transplant or hyperthyroidism - an overactive thyroid.
Low levels of calcium (hypocalcaemia), are usually due to low protein levels, not enough vitamin D, high phosphate levels, kidney disease or hypoparathyroidism - an underactive parathyroid gland.
The test is useful for anybody needing to establish levels of calcium in their blood.

Calcium is the most common mineral in the body and one of the most important. The body needs it to build and repair bones and teeth, help nerves and muscles to function, blood to clot and also help the heart to work. Vitamin D is essential to absorb calcium.
The majority of calcium in the body is stored in bone, the rest is found in the blood. If the calcium result is abnormal, a corrected calcium calculation is carried out to aid further investigation.
Around half of the total calcium in your blood is bound by albumin. Corrected calcium estimates your calcium level assuming albumin is a specified normal value.
Albumin is made mainly in the liver and helps to keep the blood from leaking out of blood vessels. It also helps carry some medicines and other substances through the blood and is important for tissue growth and healing.
Low albumin levels can indicate liver disease and can also be a marker for chronic ill-health, malnutrition and inflammation. It can also occur in kidney conditions such as nephrotic syndrome and diabetes.
Raised levels are usually caused by dehydration.
