Test Details
Blood calcium is partially bound to albumin. Changes in albumin levels can make total calcium appear misleading. Corrected calcium adjusts for albumin, providing a more accurate measure of free calcium available for the body. This is essential for assessing bone, muscle, heart, and nerve function. Low corrected calcium indicates true calcium deficiency, while high levels reflect real hypercalcemia.
Calcium is corrected according to albumin because part of blood calcium binds to albumin, and changes in albumin levels make total calcium readings misleading. Correction provides a more accurate measure of free calcium available for the body.
Low corrected calcium indicates true free calcium deficiency, which may cause weak bones, muscle cramps, and potential heart and nerve dysfunction.
High corrected calcium reflects true hypercalcemia, which can lead to kidney stones, muscle weakness, and heart rhythm disturbances.
Yes, corrected calcium reflects the calcium available for bone health, helping maintain strength and density.
Total calcium includes both albumin-bound and free calcium, while corrected calcium adjusts for albumin levels to reflect the actual free calcium used in body functions.
