Ionized calcium
Most calcium in the blood is bound to a molecule called albumin, and this calcium fluctuates depending on the level of albumin. The rest is "ionized" calcium and this is freely available for biologic processes. Labs used to only be able to measure total calcium - calcium bound to Albumin + ionized. Now we can measure ionized calcium and not be mislead that calcium is low because Albumin is low.
