What is corrected calcium?
Corrected calcium is a measurement that adjusts the serum calcium level based on albumin concentration to provide a more accurate reflection of free calcium in the blood.
How do I calculate corrected calcium?
To calculate corrected calcium, add 0.8 times the albumin level (in g/dL) to the serum calcium level (in mg/dL), then divide by 1.
Why is albumin important in calcium measurement?
Albumin binds to calcium in blood plasma, so its concentration affects the total calcium reading. Adjusting for albumin provides a more accurate measure of free calcium.
What are normal corrected calcium levels?
Normal corrected calcium levels typically range from 9.0 to 10.5 mg/dL, though this can vary slightly depending on the laboratory and patient factors.
Can I use this calculator for any type of blood test?
This calculator is specifically designed for adjusting serum calcium levels based on albumin concentration in blood plasma tests.
What units should I use for the inputs?
For the calculation, use mg/dL for serum calcium and g/dL for albumin.
How does corrected calcium differ from total calcium?
Total calcium includes both free calcium and that bound to proteins like albumin. Corrected calcium focuses on the free calcium by adjusting for protein binding.
