Calcium exists in various forms in the body. These forms are as follows:
Free ionized calcium: Calcium as anions bind with other minerals in the body and help in various functionings in the body. Calcium that binds to the protein called albumin is another type of Calcium.
Free Calcium: The most active form of Calcium is Ionized Calcium. It is also known as Free Calcium. 99% of the calcium is present in the bones whereas the rest 1% circulates freely in the blood. Half of this 1% of Calcium circulates free in the blood and the rest is bound to the albumin protein. The free calcium is metabolically active whereas the ones bound with the albumin protein aren’t metabolically active.
What is the calcium test?

– The low levels of calcium can also be because of the resistance inherited to the effects of the parathyroid hormone.
– Deficiency of Calcium in the regular diet.
– Lack of Vitamin D
– Magnesium deficiency
