This corrected calcium calculator helps you quickly perform calcium correction with albumin for patients with abnormal albumin levels. Whether you need to calculate albumin corrected calcium, use the correction calcium albumin formula, or check the equation for corrected calcium, this tool provides accurate results for both mg/dL and mmol/L. Trusted by clinicians for albumin and calcium correction and serum calcium correction.
The corrected calcium formula helps estimate the true calcium level in patients with abnormal albumin levels.
*Normal albumin is typically assumed to be 4.0 g/dL.
The corrected calcium will be 3.6 mg/dL. You can calculate it using this formula: corrected calcium = (0.8 × (4 − albumin)) + serum calcium
You can calculate the corrected calcium in three steps: 1. Determine the albumin level in g/dL. 2. Calculate the calcium level in serum in mg/dL. 3. Apply the corrected calcium formula: corrected calcium = (0.8 × (4 − albumin)) + serum calcium
Corrected calcium gives a more accurate representation of the body's actual calcium levels, especially in situations where albumin levels may be abnormal, such as with malnutrition or liver disease.
Corrected calcium levels can be influenced by various factors including kidney function, vitamin D levels, medications like diuretics, and certain diseases like hyperparathyroidism.
Calcium is an element with an atomic number of 20. In nature, it is present mainly in the form of calcium carbonate CaCO₃ in limestone and other rocks. We use calcium to maintain proper bone growth as well as allowing blood, muscles, and nerves to function correctly. The calcium symbol is Ca.
Calcium molar mass is 40.078 g/mol.
Normal calcium levels in a healthy adult should fall between 8.8-10.5 in mg/dL and 2.25-2.625 in mmol/L.
Most of the body's calcium is stored in the bones; the rest is contained in the blood. There is a problem with the regular serum test though: the calcium measured in your serum is not exclusively "pure" calcium. About 15% of it is bound to organic and inorganic anions, 45% is the biologically active ionized calcium. The rest – about 40% – is bound to albumin. This relation means that we can underestimate the serum calcium levels for a patient with low albumin (hypoalbuminemia). To avoid such situations, you should estimate the corrected calcium level.
