Total calcium on a blood test is influenced by albumin levels. Corrected calcium adjusts the measured value to give a more accurate picture of calcium status. Both calcium and albumin values appear on standard blood panels.
Open the Corrected Calcium Calculator CalculatorOpen your blood test report and look for the "Biochemistry", "Chemistry", or "Liver Function / Metabolic Panel" section.
Find "Calcium" or "Total Calcium" — note the value and units (mmol/L or mg/dL).
Find "Albumin" in the same report — it is often listed in the liver function or protein section.
Note the albumin unit — g/L (UK/Australia) or g/dL (US).
Enter both values into the Corrected Calcium calculator, selecting the correct units.

Healio360 saves corrected calcium values to your Health History. When combined with other biomarker trends in the Health Intelligence dashboard, recurring abnormalities may be flagged for your attention.
View Health IntelligenceWhy do we need to correct calcium?
Albumin binds to calcium in the blood. If albumin is low (e.g. in malnutrition or liver disease), total calcium appears falsely low. The correction formula adjusts for this.
Where is albumin on a blood test?
Albumin is typically found in the liver function test (LFT) or protein section of your blood test report.
What does high corrected calcium mean?
Hypercalcaemia (high corrected calcium) can have many causes including vitamin D excess, certain cancers, or parathyroid conditions. Always discuss results with your doctor.
