What is Corrected Calcium?

Corrected calcium is a calculated measure of blood calcium that adjusts for variations in albumin levels.‍The corrected calcium calculation adjusts for this discrepancy, providing a more accurate assessment of the body’s "free" or ionized calcium, which is essential for muscle function, nerve signalling, and bone health.‍Corrected calcium is particularly useful for people with conditions that alter albumin levels, such as liver disease, kidney disease, or malnutrition, as it reflects a more accurate calcium status in the bloodstream despite fluctuating protein levels.

What does it assess?

Corrected calcium levels assess the calcium status in the blood, adjusted for low albumin levels. Since calcium binds to albumin, low albumin can make total calcium levels appear falsely low.‍Corrected calcium calculations account for this, providing a more accurate reflection of biologically active, or "free," calcium, which is essential for bone health, muscle contractions, nerve function, and hormonal balance.

How do I optimize my Corrected Calcium levels?

Ensure adequate vitamin D levels to improve calcium absorption. Aim for 10 to 30 minutes of sunlight several times per week based on skin tone and location.‍Include vitamin D-rich foods like fatty fish, egg yolks, and fortified foods.‍ Since corrected calcium is calculated based on albumin, supporting albumin levels indirectly supports corrected calcium levels.‍Ensure a protein-rich diet with sources like lean meats, fish, eggs, legumes, and nuts. Address underlying health conditions, such as liver or kidney issues, that may impact albumin production and calcium balance. Caffeine and sodium can lead to increased calcium excretion in the urine, potentially impacting calcium levels.‍Limit caffeine intake from coffee, tea, and energy drinks, and reduce high-sodium foods to maintain a balanced calcium level.

What do high and low Corrected Calcium levels mean?

Elevated corrected calcium (hypercalcemia) can result from hyperparathyroidism, certain cancers, excess vitamin D intake, or dehydration. Symptoms may include fatigue, nausea, kidney stones, muscle weakness, and confusion.‍Low corrected calcium (hypocalcemia) may be due to low vitamin D, hypoparathyroidism, kidney issues, or low dietary calcium. Symptoms can include muscle cramps, tingling, fatigue, and in severe cases, seizures. Chronic hypocalcemia can weaken bones, increasing fracture risk, and may need dietary or supplement adjustments.
