Tag: Corrected calcium

Approximately 40% of the total calcium in your blood is bound to plasma proteins, primarily albumin. Therefore, a drop in albumin levels, a condition known as hypoalbuminemia, directly impacts the measurement of total serum calcium, creating a lab result that suggests hypocalcemia.

Approximately 50% of the total calcium in the blood is protein-bound, meaning a patient's protein levels can impact the measurement. Therefore, a low corrected calcium result signifies a true calcium deficiency in the blood, known as hypocalcemia, rather than a false low reading caused by an underlying protein imbalance.
