What is calcium correction?

Calcium with an atomic number of 20 and a molar mass of 40.07 grams. Calcium is one important element of our bones along with vitamin-D.

Calcium is mostly stored in the bones of a human body and the rest of calcium is in the blood. When the calcium level in body drops then the calcium in bones releases and the opposite is the case when the calcium level in blood is high, bones are the storage place for calcium or the extra calcium is released by the body in form of urine.

Albumin in blood has a significant part of calcium in it. Any kind of alteration in the level of albumin will directly affect the calcium levels. Low albumin levels can cause problems like hypoalbuminemia (discussed further below).

Albumin level regularity is vital. As calcium is one vital part of albumin, regular checkup for calcium is important.


How to calculate Calcium correction?

The serum test is one way to calculate body calcium level but there is a problem, calcium in the blood is not exclusively pure; 15% of it is bound with organic or inorganic anions, 45% is the estimate ionized calcium and 40% is the calcium that is attached with albumin. 

Here is the co-relation of corrected calcium formula based on albumin level:

Corrected calcium equation in mg/dl:

Corrected Calcium = (0.8 × (Normal Albumin - Albumin)) + Calcium  

Equation in  mmol/l:

Corrected Calcium = (0.02 × (Normal Albumin - Albumin)) + Calcium

Normal albumin level in the human body is about 4 g/dl.

The equation suggested is not applicable to persons suffering from end-stage renal diseases and chronic kidney diseases.

The serum test is not suitable enough to calculate calcium and albumin levels. However, there are other tests that require adjustment according to certain conditions.

On the other hand, our corrected calcium calculator can be used to precisely find out calcium albumin correction.


Calcium correction calculator:

Our calcium calculator is one precise and easy to use calculator available online. Our calculator is mostly used by persons with hypoalbuminemia.

All you need is to follow some simple and quick steps to calculate the corrected calcium.

  • Grab your laboratory test results
  • Insert the calcium level in your serum from the test
  • Insert the albumin level
  • Add the normal albumin level in the field

Afterward, click on the “calculate” button and you will get the results in seconds. You can freely switch between mg/dl to mmol/L according to the lab results.


Normal Calcium level

The normal calcium level in body changes with age and conditions. The normal level in adults ranges between 8.8 – 10.5 in mg/dL and 2.25 - 2.625 in mmol/L. lower calcium level is called hypocalcemia and a higher level than normal is said to be hypercalcemia.

Furthermore, children have lower or higher physiology calcium then adults as their bodies are more active and consume more calcium for the growth of their bones. Estimated ranges in children are 7.6 mg/dl and 10.8 mg/dl (1.9 mmol/l and 2.7 mmol/l).

Maintaining calcium level every day is important. You have to maintain the diet and regulate your calcium need. Here is a list of regular calcium (in mg) needs according to age.

  • Birth to 6 months: 200 mg
  • Infants 7–12 months: 260 mg
  • Children 1–3 years: 700 mg
  • Children 4-8 years: 1,000 mg
  • Children 9–13 years: 1,300 mg
  • Teens 14–18 years: 1,300 mg
  • Adults 19–50 years: 1,000 mg
  • Adult men 51–70 years: 1,000 mg
  • Adult women 51–70 years: 1,200 mg
  • Adults 71 years and older: 1,200 mg
  • Pregnant and breastfeeding teens: 1,300 mg
  • Pregnant and breastfeeding adults: 1,000 mg

Regulating calcium level is vital, as calcium is a significant part in albumin and both are directly proportional to each other. If the level of one drops the other drops as well.

Low albumin levels can cause problems like hypoalbuminemia.


Hypoalbuminemia

This is caused when the albumin level is low in the blood. This can be due to impaired synthesis in the liver, increased excretion or loss, abnormal utilization by body tissues or uneven distribution between body components. As calcium is directly proportional to the albumin level, so if the calcium level drops the albumin level decreases too.
