In brief: Free calcium

There is a total calcium blood test that measures both ionized calcium and calcium attached to proteins.
You may need to have a separate ionized calcium test if you have factors that increase or decrease total calcium levels, such as abnormal blood levels of Albumin or immunoglobulins.
