About The Test
How is it used
What foods are rich in calcium?
Dairy products, eggs, green leafy vegetables, broccoli, legumes, nuts, and whole grains.
What is albumin-corrected calcium?
In blood, half of the calcium is bound to albumin. An abnormally low level of albumin will increase the free calcium level in the blood and vice versa. So an albumin-corrected calcium or adjusted calcium with a formula that uses the results of total calcium and albumin tests is used.
