Calcium Test - part of the Comprehensive Metabolic Panel

The calcium blood test measures the level of calcium in the blood.

The calcium found in the blood is of two types. About half of the calcium in the blood is attached to proteins in your blood, mainly albumin. The other half is not attached to proteins. Such calcium is called free or ionized calcium.

Calcium can also be measured in the urine.
