Calcium (corrected), Plasma

Diagnostic Use

Calcium is a plasma electrolyte which plays an important role in many physiological processes throughout the body.

Approximately 50% of the plasma calcium pool is bound to albumin, with 10% bound to other anions, and 40% unbound and biologically available. As such, the total calcium is greatly influenced by the plasma albumin concentration. The corrected calcium (more correctly referred to as albumin-adjusted calcium) is a calculated parameter that gives information as to what the total calcium is likely to be assuming that the albumin level was restored to the middle of the reference interval.

Corrected calcium will be higher than the total calcium in hypoalbuminaemia, and will be lower than total calcium in hyperalbuminaemia.
